| Sensor could give prosthetic limbs new sensing capabilities
HAIFA, Israel, July 9 () -- Scientists in Israel say they've developed a flexible sensor that could be integrated into electronic skin to give wearers of prosthetic limbs new senses.While current versions of e-skin detect only touch, the new sensor using tiny gold particles and a type of resin "can simultaneously sense touch, humidity, and temperature, as real skin can do," research team leader Hossam Haick of the Technion-Israel Institute of Technology said.In addition the new sensor "is at least 10 times more sensitive in touch than the currently existing touch-based e-skin systems,[url=http://www.raybanoutletu.com/]ray ban outlet[/url]," he said in a Technion release Monday.A flexible sensor useful in the real world would have to run on low voltage to be compatible with the batteries in today's portable devices, measure a wide range of pressures, and make more than one measurement at a time, including humidity, temperature, pressure and the presence of chemicals, the researchers said.In addition, such sensors would have to be able to be made quickly, easily,[url=http://www.outletonliner.com]hemers outlet online[/url], and cheaply, they said.In the Technion sensor, gold nanoparticles are laid on top of a substrate made of PET (flexible polyethylene terephthalate), the same plastic found in soda bottles, and conduct electricity differently in response to how the substrate is bent. |
