Self-healing sensor improves “electronic skin”

Facebooktwitterredditlinkedinmail

Hossam Haick and Technion colleagues are developing materials to be integrated into flexible electronics that mimic the healing properties of human skin.  The goal is to quickly repair incidental scratches or damaging cuts that might compromise device functionality. The synthetic polymer can “heal” electronic skin in one day, which can improve the materials used to achieve  a sense of touch in prosthetics.

The new sensor is comprised of a self-healing substrate, high conductivity electrodes, and molecularly modified gold nanoparticles.  The researchers noted that “the healing efficiency of this chemiresistor is so high that the sensor survived several cuttings at random positions.”
