Abstract

Dielectric elastomer (DE) sensors have great potential for applications in soft robotics, wearable devices and medical diagnostic. A novel pressure sensor with remarkably improved force sensing characteristics was obtained through combined usage of polydimethylsiloxane (PDMS) and ionic liquid (IL). The regenerated keratin from wool was added and dispersed homogeneously in the PDMS matrix acting as reinforcing fillers. The influence of the amount of IL on the electro-mechanical properties of the composites was investigated. One obvious result was that the permittivity of the ILcontaining elastomers increased dramatically with the increased amount of IL loaded. Furthermore, the sensitivity of the composite elastomers as pressure sensors was investigated by recording the response of the voltage when a small force is applied to the top surface of the pressure sensor. The elastomers with IL loaded exhibit excellent response of the voltage and the maximum sensitivity of the composite elastomer is 2.64 mV/N.
