cochlear implant
February 10, 2014 | Innovations

Cochlear implants are medical breakthroughs that have provided the sense of sound to those who would otherwise be deaf or severely hard of hearing. These devices, which electrically stimulate the auditory nerve, rely on external components including a transmitter, microphone and power source, that are wired from around the ear to the wearer's skull. Researchers at MIT have developed a low-power signal-processing chip that could be used to create a cochlear implant that no longer requires external components. The new cochlear implant would utilize a sensor that detects vibrations from bones in the middle ear and transmits them to a microchip implanted in the ear. These vibrations would then be converted into an electrical signal and sent to an electrode in the cochlea. To lower the power requirements of the converter chip, the researchers optimized the arrangement of low-power filters and amplifiers, and developed a more power-efficient signal-generating circuit. This new cochlear implant could even be charged wirelessly in only two minutes using a device that plugs into a smart phone, for a charge that would last up to eight hours.

Engineers at Florida International University are designing the next generation of antennas using origami. The principles of origami enable the antennas to be folded to only a few centimeters, and in a variety of shapes, but still possess ultra-broadband capabilities. The antennas are typically made from paper, but the researchers are also exploring using plastics and other materials. Advanced inkjet printing techniques are used to apply the conductive elements of the antennas that enable signal reception. These folding antennas possess a wide range of applications ranging from space, to medicine, to the military.

Computing and engineering students from the University of Southampton won the Thales Project Arduino Competion, which challenged students to design something using the Thales Arduino open-source electronic microprocessor platform. Projects needed to be in the areas of transport, aerospace, defense or security, and students were invited to film the progress of their efforts. The Southampton students designed a soldier-monitoring smart helmet which was fabricated using a 3D printer. The helmet was programmed using the Arduino platform to record the wearer's heart rate, body position and body temperature. Check out a video of the students' project below:

SPARK

The Science Play and Research Kit (SPARK) competition challenges participants to reimagine the chemistry set for the 21st century and generate a new set of experiences and activities that encourage imagination and interest in science and engineering. The competition is not limited to chemistry, but is looking for ideas that can engage kids as young as 8 and inspire people who are 88; that encourage kids to explore, create, build and question; and honor kids’ curiosity about how things work.

Apply by 7 January 2014 at reimaginechemset.org to win prizes up to US$5,000!

IBM researchers have found a novel application for polymers that are used in semiconductor manufacturing to etch silicon wafers on a very small scale. By manipulating the materials at the nanoscale, the researchers created what they have dubbed "ninja polymers" that can be used to kill bacteria such as MRSA. Essentially, the ninjas target bacteria based on electrostatic charge, attach to and destroy their cell membranes and the harmful content within, and then stealthily disappear into the body by biodegrading. This is all accomplished without any harmful effects on healthy tissue and with little chance of developing resistance to the polymers.  Additional future applications of the ninja polymers might be the targeted delivery of drugs within the body, or as bacteria-fighting agents in household cleaners.

Engineers at the University of Washington have designed a system that enables wireless devices to be operated without the use of batteries. The system works by making use of what is known as "ambient backscatter"; or the TV and cellular transmissions that surround us every day. The engineers equipped pairs of small devices about the size of  credit cards with antennas, enabling them to detect TV signals, convert them to electrical power, and then reflect them to one another to communicate in a manner somewhat akin to Morse code. The engineers were able to get the devices to successfully communicate even when 6.5 miles away from a TV tower; and with a transmission rate large enough to send and receive data such as a sensor reading, text, or contact information when 2.5 feet apart outdoors. Examples of applications of this technology might include monitoring bridge integrity, wearable devices, smart homes, or autonomous sensor networks.
