The sensing performances of MPP piezoresistive sensor. a) Current response ΔI/I o versus time. b) The relative change of the current (ΔI/I o) as the pressure load changes for the MXene/PEI sensors with different MXene concentrations. c) The response time (163 ms) and recovery time (123 ms) of MPP sensor at compression speed of 200 mm s−1. d) The durability test of the sensor under 10 000 continuous loading‐unloading cycles. e) Dynamic rheological behavior of MXene/PEI fibrous network from −120 to 200 °C. f) The stress–strain curves of MXene/PEI fibrous network and g) the sensitivities of MPP sensor under different temperature conditions from RT to 150 °C. h) The cyclic piezoresistive sensing performance of the MPP sensor at 100 °C over 2000 cycles. i) Comparison of sensitivity and sensing range for different piezoresistive sensors.
