a Relative current change based on the optimized sensing layer under different pressures (0.032 kPa–1000 kPa). b Comparison of the sensitivity of our pressure sensor with other reported literatures. c Response and recovery times of the HPPS under the pressure of 17 kPa. d Current-voltage curves of the HPPS under different pressures. e Dynamic response of the HPPS under loading/unloading cycles from low pressure to high pressure. f Dynamic response of the HPPS under 100 kPa at different frequencies. g Detection of tiny pressure under pre-compression of 643 kPa. h Repeatability performance of HPPS over 35,000 loading/unloading cycles under the pressure of 28 kPa, 50 kPa, and 200 kPa respectively.
