Using tiny gold particles and a kind of resin, a team of scientists at the Technion-Israel Institute of Technology has discovered how to make a new kind of flexible sensor that one day could be integrated into electronic skin, or e-skin. If scientists learn how to attach e-skin to prosthetic limbs, people with amputations might once again be able to feel changes in their environments. The findings appear in ACS Applied Materials & Interfaces.
The secret lies in the sensor’s ability to detect three kinds of data simultaneously. While current kinds of e-skin detect only touch, the Technion team’s invention “can simultaneously sense touch, humidity and temperature, as real skin can do,” says research team leader Prof. Hossam Haick. Additionally, the new system “is at least 10 times more sensitive in touch than the currently existing touch-based e-skin systems.”
