Fig. 4: Mechanical response of the fibrous mat-based pressure sensor.

a Illustration of the structural fabrication of the sensor. b Current–voltage curves. c Variation in the resistance and sensitivity of the PEDOT/MWCNT@PU- and MWCNT@PU-based pressure sensors. d The response and recovery time of the PEDOT/MWCNT@PU and MWCNT@PU-based pressure sensors. e Continuous low-pressure loading detection. f Long-term loading/unloading cycles for stability. g Comparison of the performance of fibrous pressure sensors
