Abstract

This work presents how the lifetime of silicone-based dielectric elastomer actuators (DEAs) is affected by the choice of silicone elastomer material, humidity and temperature at constant DC electric fields and membrane prestretch. High (>50%RH) humidity levels are found to significantly decrease the lifetime of silicone-based DEAs under DC actuation, whereas temperature and the type of silicone elastomer have a more limited impact. Under a constant DC electric field of 83V/μm and a membrane prestretch of 1.3, all DEAs operating at 80°C – 90%RH fail within 24 hours whereas DEAs actuated at 20°C – 10%RH all survive over 14 days without any failure.
