Resistance measurements of polydimethylsiloxane (PDMS) stretch-sensors embedded with a conductive gel

Abstract

A novel conductive gel and soft silicone (PDMS) composite material was investigated as a potential stretch-sensor material for measuring deformation of elastic surfaces. Initial trials involved resistance measurements on un-stretched sample strips and when strips were stretched to 200% of initial length, resulting in good consistency in resistive feedback between all samples tested. Temperature effect on resistance was also explored. However, due to the small sample size used more extensive testing is suggested in order to confirm these results.
