Abstract
Flexible pressure sensors have been widely concerned because of their great application potential in the fields of electronic skin, human–computer interaction, health detection, and so on. In this paper, a flexible pressure sensor is designed, with polydimethylsiloxane (PDMS) films with protruding structure as elastic substrate and poly(3,4-ethylenedioxythiophene)/poly(styrenesulfonate) (PEDOT:PSS)/cellulose nanocrystals (CNC) as conductive-sensitive material. The flexible pressure sensor has a wide linear detection range (0–100 kPa), outstanding sensitivity (2.32 kPa–1), and stability of more than 2000 cycles. The sensor has been proven to be able to detect a wide range of human movements (finger bending,…
