Published: June 5, 2023

Abstract Recently, polymer materials have been at the forefront of other in building high‐performance flexible electronic skin (e‐skin) devices due to conspicuous advantages including excellent mechanical flexibility, good compatibility, and high plasticity. However, most research works just paid considerable attention effort design, construction, possible application e‐skins that reproduce tactile perception human sensory system. Compared with sensing devices, aim imitate non‐contact features system tend avoid undesired issues such as bacteria spreading wear. To further promote development where complement each other, significant progress advances achieved field enabled for both applications. In this review, latest material‐based regard tactile, capabilities their practical applications are introduced. The fabrication strategies role highlighted. Furthermore, we also review integrated polymer‐based into robots prostheses, smart gloves, VR/AR addressed some representative problems demonstrate suitability human–machine interactions. Finally, current challenges construction highlighted promising properties direction, by taking advantage materials, outlined. image
