A flexible, conductive and simple pressure sensor prepared by electroless silver plated polyester fabric

A flexible and lightweight pressure sensor based on polyester (PET) fabric was prepared, and the conductive polymer polyaniline (PANI) was polymerized in situ on the surface of PET fabric to form a film. The reduction performance of PANI was used to reduce Ag+ to form an Ag-0 catalytic center, causing subsequent electroless silver plating. The silver-plated PET fabrics can be used as a novel, flexible and simple pressure sensor to produce various of signals based on body movements. This flexible pressure sensor has good linearity, high sensitivity, wide response range and fast response time to distinguish different motions due to the magnitude and frequency of the pressure. We can believe that this flexible sensor is made of electroless silver-plated PET fabric when applied to human body, like palm, plantar and other parts can effectively detect motion in health monitoring.
