STRETCHABLE PIEZORESISTIVE SENSORS WITH GRAPHENE AND POLYANILINE COATED WOVEN POLYESTER FABRICS

Abstract

Strain is the concept that expresses how much a material changes its shape under mechanical action. Strain sensors are smart materials that can be used in mechanical characterization, structural quality control and, more recently, wearable electronics. In the literature, there are studies that can detect strain by using a piezoresistive mechanism. Piezoresistive effect defines the electrical conductivity (or resistivity) changes of a material under mechanical stress. The developed fabric strain sensor can be used in smart textiles and future applications for wearable electronics.
