摘　　要：To accurately probe the tactile information on soft skin,it is critical for the pressure sensing array to be free of noise and inter-taxel crosstalk,irrespective of the measurement condition.However,on dynamically moving and soft surfaces,which are common conditions for on-skin and robotic applications,obtaining precise measurement without compromising the sensing performance is a significant challenge due to mechanical coupling between the sensors and with the moving surface.In this work,multi-level architectural design of micro-pyramids and trapezoid-shaped mechanical barrier array was implemented to enable accurate spatiotemporal tactile sensing on soft surfaces under dynamic deformations.Trade-off relationship between limit of detection and bending insensitivity was discovered,which was overcome by employing micropores in barrier structures.Finally,in-situ pressure mapping on dynamically moving soft surfaces without signal distortion is demonstrated while human skin and/or soft robots are performing complicated tasks such as reading Braille and handling the artificial organs.
