Research Progress in Flexible Wearable Strain Sensors Based on Polydimethylsiloxane

Abstract

Traditional electronic strain sensors based on metal and semiconductor materials have poor flexibility and wear-ability, which are not applicable for stretchable sensors. With the development of flexible electronic materials, wearable electronic devices show great market prospects. Flexible strain sensors have many unique advantages, such as good biocompatibility, wearable, stretchability and elasticity, which become a hotspot of research. The research progress is the preparation technology, performance and application of PDMS based piezoresistive and capacitive flexible strain sensors were summarized in this paper. Finally, challenges, important directions and perspectives related to PDMS flexible strain sensors were prospected.
