Research Progress of Flexible Piezoresistive Sensors Based on PDMS
The flexible piezoresistive sensors based on polydimethylsiloxane(PDMS)as substrate have a rapid development in recent years,and has a broad application in fields such as human motion and health detection,electronic skin,and smart ro-bots.The sensing mechanism and main performance indices of the flexible piezoresistive sensors were firstly introduced,and then the research progress of the PDMS-based flexible piezoresistive sensors was summarized in details,especially the combination of PDMS and various conductive fillers and the construction of microstructure.Finally,the problems were pointed out,and the de-velopment direction of PDMS was discussed.
