    3D printed Organs

     

    “Our approach is consistent with other forms of 3D printing because it’s an additive process,” says Renard, “but what is unique is our application of the process in the field of cell biology and tissue engineering.” There is a device revolutionizing creations and medical advancements! The act of 3D printing organs has become a new research topic for many scientists. The idea is to very carefully design and shape certain organs; after the organ is designed it is printed using a 3D printer. The Princeton researchers wanted to build on their knowledge, and so, the team joined up with researchers at Johns Hopkins to build the electronic ear. Their 3D printer combined calf cells with a hydrogen matrix material to form the ear cartilage, and silver to form the antenna coil. During testing, they were able to pick up radio waves in stereo using complimentary left and right side ears. Later on they hope to be able to detect acoustic energy directly using other built-in sensors. Other researchers have used 3D printing of a material called carbomorph to create that change resistance when bent or stressed. These researchers have also been able to print capacitive button sensors to measure changes in capacitance, and even connectors for hooking things together. An alternative to painful rib grafts, which result in ears that neither function well nor look natural, a normal ear is scanned and a mould made by a 3D printer. Collagen is injected into the mould, which acts as a scaffold in the formation of cartilage. The hope is that human trials could take place within three years. 3D printing has been used for pioneering work within foetal medicine, too. In 2009, Brazilian designer and Royal College of Art PhD student Jorge Lopes introduced the use of 3D printing to create models of unborn children within the womb. Lopes used MRI scans “to see inside the belly of a pregnant woman,” he says. 3D printing also has huge potential to help disability. Magic Arms is shortlisted for the Design Museum’s Design of the Year 2013, and enables Emma Lavelle, a child born with arthrogryposis, to use her arms, a function that was previously impossible. Magic Arms is Emma’s nickname for the Wilmington Robotic Exoskeleton (WREX), an assistive device made up of a bespoke butterfly-patterned jacket and arms that are 3D-printed in durable ABS plastic. The design was originally made with CNC technology for patients older than two-year-old Emma, but 3D printing enabled it to be translated into a smaller version that is light enough for Emma to wear and take everywhere. If a piece breaks, her mother can simply photograph the broken element and a new one is printed out and sent through the post. Clearly 3D printed organs have revolutionized both the medical and the engineering advancements, and will, hopefully, continue to do so.

  • Innovative Work- Earphone Alarm

    Earphone Alarm

    The Earphone Alarm, also known as a Anshinkun-2 is a new Japanese gadget that works as a small timer, worn just like an earphone. It’s very light, so it does not cause discomfort, and small so it’s not unattractive, nor does it get in the way. Its’ portable, and runs on batteries so it does not need to be plugged in or charged. This gadget is very useful for multiple things, such as if you’re on a train for example and fall asleep, the timer will go off to wake you up so you don’t miss your stop. Another bonus about the Anshinkun-2 is because it’s in your ear, it won’t disrupt other people, and only you can hear it. Other situations it would be useful in would be if you need to work for a certain amount of time, just set it to go off when you need to stop. It’s handy when cooking because you can time your food and walk around the house or go out and not miss the alarm on the cooker, for example. Another big selling point about it is its waterproof, so you can use in when showering or skiing. It’s manufactured by the Japanese company Honda Tsushin Kogyo, and sells on the market for 11 dollars.

    Though it is a great product, there are also environmental factors to take into consideration. An example of this would be the manufacturing that takes place, the use of the product and the disposal of the packaging and batteries that it needs to function, which are bad for the environment while being made, and if they are not recycled properly. Also, the actual making of the gadget is not environmentally friendly, because like many, if not all factories, the smoke and chemicals released while the product is being made are bad for the atmosphere. When the earphone alarm is actually made, it then has to be shipped to other various countries which will be selling the product. The shipping not only costs money, but the shipment also has to be disposed of once the product is in its designated area, or should be recycled properly which is no guarantee. Then once it has actually reached the destination in which it will be sold, its packaging has to be taken care of properly, or it’ll just be thrown away and regarded as waste. We also should take into consideration what will happen with the actual product or earphone alarm when the buyer has finished with it. It could be recycled for parts, but will most likely just be thrown away.

  • The Telephone

    The Telephone

    Invented in the mid 1870s by Alexander Graham Bell, the telephone revolutionized communication and has brought the world closer together.  Modern telephones have a microphone to speak into, an earphone or speaker that reproduces the voice of the other person, a ringer which makes a sound to alert you when a call is incoming, and a keypad to enter the telephone number of the telephone you are calling. The microphone and earphone are usually built into a handset which is held up to your face to talk. The keypad may be part of the handset or of a base unit to which the handset would be connected. Although originally designed for simple voice communications, most modern telephones have many additional capabilities. They may be able to send and receive text messages, take and display photographs, play music, and surf the Internet. These days’ Smartphone’s also integrate all computing needs.

    Environmental impact of cell phones

    There are 6.7 billion people on this planet and 61 percent have a cell phone subscription, that’s 4.1 billion. The average consumer will use their cell phone for less than a year, during that year it will use 4,221 mega joules of energy, the equivalent of 32 gallons of gas, and emit 112 kilograms of C02. Transferring 1 GB of data over a 3G network will use 939 mega joules of energy, the equivalent of 7.3 gallons of gas, and emit 17kg of C02. An unused but plugged in charger still draws about half a watt. If everyone left their charger plugged in ALLDAY, it would waste enough electricity to power 28,000 homes. 140,000,000 cell phones (4 per second) will end up in landfills this year. Leeching 80,000 lbs of lead into the earth, in that landfill is 4.7 tons of gold worth $56 million and 49 tons of silver worth $8.4 million. For every 515 cell phones recycled, it saves enough energy to power one home for a year. If all these thrown away cell phones were recycled, it would save enough energy to power 272,000 homes. To charge every cell phone in use on earth would require the equivalent of 584,000 gallons of gas and produce 35,000,000 pounds of carbon dioxide, imagine that every day, if we all charged our phones half as often it would be the equivalent of taking a million cars off the road. Although mobile phones only make up a small percentage of the e-waste mountain, manufacturers are aware of the need to address the issue. Leading makers, including Motorola, LG, Sony Ericsson and Philips, have all implemented eco-design aspects into their production lines, including reducing the amount of hazardous substances used in their products. Nokia, the world’s largest mobile phone manufacturer, produces a handset every nine seconds. It has decided to implement requirements set out in the EU Restriction of Hazardous Substances Directive in all 10 of its factories around the globe. The RoHS Directive bans six substances (lead, cadmium, mercury, hexavalent chromium, PBB and PDBE) from products that are either made or sold in the EU.

     

  • Food Industry

    The food industry is a complex, global collective of diverse businesses that together supply much of the food consumed by the world population. Only subsistence farmers, those who survive on what they grow, can be considered outside of the scope of the modern food industry.

    Processed food sales worldwide are approximately US$3.2 trillion. In the U.S., consumers spend approximately US$1 trillion annually on food, or nearly 10 percent of the Gross Domestic Product. Over 16.5 million people are employed in the food industry.

    In the United Kingdom, the food industry is extensive. It employs over half a million people and has a turnover of £70bn. It is the largest manufacturing sector in the UK and represents around 15% of the total manufacturing sector in the UK. Around 13% of the people working in manufacturing in the UK work in the food and drink industry.

    A vast global transportation network is required by the food industry in order to connect its numerous parts. These include suppliers, manufacturers, warehousing, retailers and the end consumers. There are also companies that add vitamins, minerals, and other necessary requirements during processing to make up for those lost during preparation. Wholesale markets for fresh food products have tended to decline in importance in OECD countries as well as in Latin America and some Asian countries as a result of the growth of supermarkets, which procure directly from farmers or through preferred suppliers, rather than going through markets.

    The constant and uninterrupted flow of food products from distribution centers to store locations is a important link in food industry operations. Distribution centers run more efficiently, output can be increased, costs can be lowered, and manpower better utilized if the proper steps are taken when setting up a material handling system in a warehouse.

    With populations around the world concentrating in urban areas, food buying is increasingly removed from all aspects of food production. This is a relatively recent development, having taken place mainly over the last 50 years. The supermarket is the defining retail element of the food industry, where tens of thousands of products are gathered in one location, in continuous, year-round supply. Restaurants, Cafes, Bakeries and Mobile trucks are also ways consumers can purchase food.

    Food preparation is another area where change in recent decades has been evident. Today, two food industry sectors are in apparent competition to top the food industry. The grocery industry sells fresh and largely raw products for consumers to use as ingredients in home cooking. The food service industry by contrast offers prepared food, either as finished products, or as partially prepared components for final . “assembly”.

    Sophisticated technologies define modern food production. They include many areas. Agricultural machinery, originally led by the tractor, has practically eliminated human labor in many areas of production. Biotechnology is driving much change, in areas as diverse as agrochemicals, plant breeding and food processing. Many other areas of technology are also involved, to the point where it is hard to find an area that does not have a direct impact on the food industry. Computer technology is also a central force, with computer networks and specialized software providing the support infrastructure to allow global movement of the myriad components involved.

  • Water Bobble

    Australian designer, Karim Rashid, has created a revolutionary product that is not only environmentally friendly but extremely convenient.

    “We all love bottled water.In fact, we are obsessed by the convenience of it, but unfortunately, this doesn’t lead to a sustainable future.”

    He has successfully reinvented the water bottle developing the bobble, which takes tap water and filters it into clean water as you drink.

    Research shows, Australians alone spend $544 Million every year on disposable and portable water bottles. Each year, nearly 300,000 barrels of oil are used to make plastic water bottles, most of which are thrown away. Littering our pavements and ending up in landfills.

    Rashid set out to satisfy his desire for fresh, clean, portable water while minimising the considerable costs bottled water imposes on our environment and ourselves. He then invented a recyclable and resilient water bottle which holds low cost and is aesthetically pleasing. The bottle is not only sustainable but also made from recycled plastic, ensuring every aspect of its creation and existence is environmentally friendly.

    Disadvanage: Filter has to be replaced every 2 months or 150 litres.

  • Steve Jobs

    Steve Jobs, born in San Fransisco on 1955, is well know for his original and innovative products. After attending the Cupertino Junior High School, Jobs joined Reed College, but dropped out after only one semester. He continued auditing certain classes, of which one is calligraphy. This calligraphy class soon changed his life dramatically.

    After meeting Steve Wozniak while working for HP in a summer job, Jobs  joined Atari, a manufacturer of popular video games. After acquiring some experience there, Steve Jobs, together with Steve Wozniak and Ronald Wayne founded Apple in 1976. Having been friends with Steve Wozniak for several years now, Steve Jobs was able to convince Steve Wozniak to assemble and sell computers.

    Steve Jobs release the Macintosh in 1984, it was the first commercially successful computer with a graphic user interface (GUI). Not long after, however, an internal power struggle caused the recently hired CEO John Sculley to relieve Steve Jobs of his duties as the head of the Macintosh division.

    Around the same time, Steve Jobs founded another company, NeXT Computer. The company’s focus was to develop high-end computers, and those who could afford it developed a  strong following due to its technical strengths. Just two years later, Steve Jobs bough The Graphics Group, which is a company that is now known as Pixar.

    Several years later, in 1998, Apple bought then NeXT Computer company, bringing Steve Jobs back to the company. He soon became CEO after the board of directors lost confidence in the CEO of that time. Steve Jobs straight away terminated several projects

    such as the Newton project. He also assigned new project leaders and fired several employees. During this time employees developed a fear of encountering Steve

    Jobs while riding in the elevator “afraid that they might not have a job when the doors opened”.

    Since the return of Steve Jobs, Apple has entered several new markets, under which the portable music player market with the iPod in 2001, the phone market with the iPhone in

    2007, and recently the tablet market, with the iPad. Ever since, Steve Jobs has been considered one of the greatest innovators in modern history.

    Fun Fact: Steve Jobs officially earns one dollar a year.

  • Environmentally Friendly Toilets

    A Swedish company is selling dry toilets to help countries where water or sewerage systems are a concern. These toilets work by keeping the urine and the solid waste separate and using the second to create manure for farms. So far, the company has sold about 2,000 dry toilets, but the demand is growing worldwide.

    These toilets work by keeping the urine and the solid waste separate and using the second to create manure for farms. So far, the company has sold about 2,000 dry toilets, but the demand is growing worldwide. Read more…

    Here are some short excerpts from the India News article.

    ‘Don’t mix, don’t flush, don’t waste’ is the slogan of a Swedish entrepreneur selling dry toilets – a revolutionary concept that not only saves water but also converts human waste into manure.

    Sven Ingvar-Nilsson, 77, has been successfully using the dry toilet design for the last 11 years at his massive farm on the outskirts of this small Swedish town. He says that the concept not only uses human waste but also saves a lot of water that is wasted every time you flush.

    The urine section is rinsed using approximately 0.1 litres of water each use. The urine is led to a tank where it is collected for further transport, preferable for spreading as fertilizer in garden or agriculture. Solids fall into a bin housed in an insulated container in which negative pressure is created by a fan and vent.

    The solid waste dries and thus bacteria and viruses are eliminated by a simple and reliable method. After a drying period of six months the solids can be composed, burned or dug down in the soil where it is quickly broken down. A standard bin (holding 80 litres) will need to be emptied every three months for normal family use.

  • Wake-up Light

    Wake up light

    Philips brought out the wake up light around 2008. This light is a new form of alarm clock.

    The light will simulate a sunrise and give the person a pleasant way of waking up, this is because of a natural reaction the user will have towards the sun rise. Nature’s alarm clock is the sun rise and in the past (before technology) people would rely solely on the sun, they go to bed once the sun sets and wake up when it rises. This lamp uses this natural reaction to wake you up very pleasantly.

    The theory behind it is that when the sun rises your body slowly prepares you to wake up by creating fewer hormones which make you sleep (adenosine and melatonin) and will be breaking down the melatonin and adenosine to wake you up again.

    The product was tested in different parts of the world especially where it is dark such as Norway during the winter. After about 6 weeks 98% of the citizens who tested the product wanted to continue. Links 4 and 5 show the results of 60 days as well as after two, four and six weeks.

    The price can range from 109€ to 129€ this is a lot of money but I believe it will make a large difference when used. There are also models where there is an iPod/ iPhone charger dock attached to the light to play your music while using the light.

  • Touchscreen

    A touchscreen is an electronic visual display that can detect the presence and location of a touch within the display area. The term generally refers to touching the display of the device with a finger or hand. Touchscreens can also sense other passive objects, such as a stylus. Touchscreen is common in devices such as all-in-one computers, tablet computers, and smartphones.

    The touchscreen has two main attributes. First, it enables one to interact directly with what is displayed, rather than indirectly with a cursor controlled by a mouse or touchpad. Secondly, it lets one do so without requiring any intermediate device that would need to be held in the hand. Such displays can be attached to computers, or to networks as terminals. They also play a prominent role in the design of digital appliances such as the personal digital assistant (PDA), satellite navigation devices, mobile phones, and video games.

    The first touch screen was a capacitive touch screen developed by E.A. Johnson at the Royal Radar Establishment, Malvern, UK. The inventor briefly described his work in a short article published in 1965 and then more fully – along with photographs and diagrams – in an article published in 1967. A description of the applicability of the touch technology for air traffic control was described in an article published in 1968.

    Technologies

    Resistive

    A resistive touchscreen panel is composed of several layers, the most important of which are two thin, electrically conductive layers separated by a narrow gap. When an object, such as a finger, presses down on a point on the panel’s outer surface the two metallic layers become connected at that point: the panel then behaves as a pair of voltage dividers with connected outputs. This causes a change in the electrical current, which is registered as a touch event and sent to the controller for processing.

    Surface acoustic wave

    Surface acoustic wave (SAW) technology uses ultrasonic waves that pass over the touchscreen panel. When the panel is touched, a portion of the wave is absorbed. This change in the ultrasonic waves registers the position of the touch event and sends this information to the controller for processing. Surface wave touchscreen panels can be damaged by outside elements. Contaminants on the surface can also interfere with the functionality of the touchscreen.

    Infrared

    An infrared touchscreen uses an array of X-Y infrared LED and photodetector pairs around the edges of the screen to detect a disruption in the pattern of LED beams. These LED beams cross each other in vertical and horizontal patterns. This helps the sensors pick up the exact location of the touch. A major benefit of such a system is that it can detect essentially any input including a finger, gloved finger, stylus or pen. It is generally used in outdoor applications and point of sale systems which can’t rely on a conductor (such as a bare finger) to activate the touchscreen. Unlike capacitive touchscreens, infrared touchscreens do not require any patterning on the glass which increases durability and optical clarity of the overall system.

    Acoustic pulse recognition

    This system, introduced by Tyco International’s Elo division in 2006, uses piezoelectric transducers located at various positions around the screen to turn the mechanical energy of a touch (vibration) into an electronic signal. The screen hardware then uses an algorithm to determine the location of the touch based on the transducer signals. The touchscreen itself is made of ordinary glass, giving it good durability and optical clarity. It is usually able to function with scratches and dust on the screen with good accuracy. The technology is also well suited to displays that are physically larger. As with the Dispersive Signal Technology system, after the initial touch, a motionless finger cannot be detected. However, for the same reason, the touch recognition is not disrupted by any resting objects.

    Construction

    There are several principal ways to build a touchscreen. The key goals are to recognize one or more fingers touching a display, to interpret the command that this represents, and to communicate the command to the appropriate application.

    In the most popular techniques, the capacitive or resistive approach, there are typically four layers;

    1. Top polyester coated with a transparent metallic conductive coating on the bottom
    2. Adhesive spacer
    3. Glass layer coated with a transparent metallic conductive coating on the top
    4. Adhesive layer on the backside of the glass for mounting.

    When a user touches the surface, the system records the change in the electrical current that flows through the display.

  • Kevlar

    Kevlar is a material developed by DuPont in 1965 but it was only used in 1970 for commercial use. Kevlar is used in body armor and armored vehicles, it is also applied in clothing to protect the user from cuts. Sports equipment such as bicycle tires to stop punctures, it is applied to table tennis paddles, motor cycle clothing, and racing sails. Kevlar has even been used in audio equipment since it has acoustic properties, drumheads, woodwind reeds, rope, cable, brakes, electricity generation, construction of buildings, and expansion hoses and joints.

    Kevlar is strong because of the weave which is very similar to small spider webs. It was invented by Stephanie Kwolek and Herbert Blades. The weave consists of a liquid and a solid also known as an aramid weave. These weaves corrode in exposed to chlorine but is resistant to heat.

    There are different types of Kevlar, they are all numbered and have their own use. Kevlar K-29 for example is used industrially for cables and brakes and armor while Kevlar K-49 is used in tires to replace rubber and bicycle frames but also in the hull of a boat because it is incredibly strong.

    The chemical composition of Kevlar is poly para-phenyleneterephthalamide (composite.about.com). Aramids belong in the nylon family.

    Kevlar is also very light and extremely strong of course and the tensile strength is high. However it does absorb moisture which makes it more sensitive to environments it is also harder to cut because you will need special scissors.

    The material is rather expensive to get and can get to about 33 dollars per yard but you have to buy in great amounts.

    This is a table of the three main Kevlar types 29, 49, and 149. (composite.about.com)
