Stretchable ionics for transparent sensors and actuators

2019

Patent

rm

A class of devices enabled by ionic conductors is highly stretchable , fully transparent to light of all colors , biocompatible or biodegradable , and capable of operation at frequencies beyond 10 kilohertz and voltages above 10 kilo volts . These devices enabled by ionic conductors can be used as large strain actuators , full - range loudspeakers , as strain or pressure sensors and as stretchable interconnects . The electromechanical transduction is achieved without electrochemical reaction . When large stretchability and high optical transmittance are required , the ionic conductors have lower sheet resistance than all existing electronic conductors .
