Seniors, and other people at risk of falls, may one day feel a bit steadier with the further evolution of vibrating insoles able to reduce falls by subtly stimulating the soles of the feet. Falls are a leading cause of injury among seniors, and are often the result of lack of balance and unsteady gaits caused by reduced sensations in the feet. Previous research has shown that stochastic resonance can mitigate some of the deficits in the sensory system by creating a sort of 'white...

Nanonsheet material able to cling to irregular skin could provide a more effective treatment for burn victims. The nanosheets will be made by first spinning the biodegradable polymer poly (L-lactic acid) (PLLA) in a test tube of water, breaking the material down into smaller pieces. This mixture will then be poured onto a flat surface, where the pieces overlap and merge to dry into a single sheet. The unique makeup of the nanosheet will allow it to tightly cover even tiny bumps and...

The vest will combine the technology of driverless cars with the natural skills of bats and pit vipers to help the visually impaired navigate. The system will feature a vest equipped with sensors and emitters that will be arranged to provide 360 degrees of detection. The system will include a LiDAR laser, which is used in driverless cars; ultrasound, used by bats for echo-location; and infrared, used by pit vipers for thermal location, which combine to deliver extremely effective...

The idea is to take smartphone technology on the road with a new smart bike concept, which will even feature a rear view camera. The technology will be centered around a smartphone that will attach to the handlebars with a magnetic mount. The phone will control the bike's components, which will include a WiFi/Bluetooth module and four laser projectors that will delineate a bike lane, and also display the real-time video stream from the camera mounted on the rear of bike.

The portable wind turbine puts the power of the wind in the palm of your hand, packing a 15W generator into its small, lightweight frame. The turbine folds into an impressively portable 12-inch cylinder for transport or storage, and can be easily set up once on location. Its three, 11-inch aluminum legs can be extended and arranged to create a tripod base or laid flat to form a pedestal, allowing the turbine to harness the wind and charge its 15,000 mAh battery. Smartphones and...

The new bike lock will help discourage bike theft by disengaging the bike's steering system, making it a bit harder for thieves to 'snip, grab and ride.' The system will be integrated into the bike's stem, where it will be locked or locked by a key. The system will be securely fastened for riding, but a simple turn of a key will disconnect the handlebar stem from the fork--making it impossible for anyone to steer the bike. In addition to deterring thieves, the handlebar...

By isolating the chitin in shrimps' exoskeleton it is possible to create an alternative to plastic that can break down in two weeks to provide nutrients for plants. The approach will include mimicking the molecular structure of the chitin as closely as possible and then adding silk derivatives and wood flour. These additions will help to ensure the material will not crack or shrink while it is being used for injection molding. The new material can be altered for use in water or dyed...

The new handheld radiation camera will offer a cheaper, faster method of checking for radiation in real time. Modern radiation-detecting equipment is bulky, slow, and extremely expensive, and needs to be cryogenically cooled. In contrast, this device will be equipped with a cadmium-zinc-tellurium, room-temperature gamma ray detector. The lightweight detector will be remarkably accurate, and will be able to lay a gamma-ray map over the image of an area, allowing the user to 'see'...

The idea is to develop a way to use piezoelectric materials to harness the energy in loud sounds, potentially leading to quieter engines and new way to harness wind power. First approach is to use a piezoelectric material to build a very thin, sensitive membrane of aluminum able to transform sound vibrations into enough electricity to power a small sensor. They it will be possible to attach the membrane to a liner that will quiet the sound of the engine by canceling out certain...

The dragonfly-inspired turbine will be small enough to be erected in a backyard and will harness energy from winds as low as four miles per hour. Based on the dragonfly's ability to float on light breezes and still navigate through gale-force winds, the turbine will be made of lightweight carbon and polycarbonate, which will allow it to harness low winds and at low altitudes. It will also withstand the force of larger winds, due to its slim-line design, and, standing only 20 meters...
