Improved shock tube method for dynamic calibration of the sensitivity characteristic of piezoresistive pressure sensors

•An improved shock tube method for dynamic calibration of the sensitivity of piezoresistive pressure sensors is proposed.•The over-estimated shock wave pressure is compensated with the establishment of ISW velocity attenuation model.•A hybrid adaptive mode decomposition method is presented to correct the dynamic response signal.•The propagation and evaluation of the sensitivity calibration uncertainty of is investigated.
