Recently, electronic skin has been advanced to imitate the function and performance of human skin for the applications such as prosthetics, secondary skin, health monitoring and so on. In order to emulate the tactile sensing mechanism for human’s cutaneous cell, it is required to understand the visco-poroelastic behavior of human tissue and human sensory receptor, but not explored. In this talk, we report the cell-inspired tactile mechanism in order to implement highly sensitive artificial sensor skin. In particular, we describe an accurate mechanism of deformable polymer ion pump that exhibits visco-poroelastic behavior derived from deformation of polymer chain (viscoelastic) and ion migration (poroelastic) under pressure. As a result, we could demonstrate highly sensitive human cell-inspired tactile sensor based on polymer ion pump that is activated by ion migration. |
