Bioinspired Passive Tactile Sensors Enabled by Reversible Polarization of Conjugated Polymers

Abstract

Highlights Fully organic and passive tactile sensors are developed via mimicking the sensing behavior of natural sensory cells. Controllable polarizability of conjugated polymers is adopted for the first time to construct passive tactile sensors. Machine learning-assisted surface texture detection, material property recognition, as well as shape/profile perception are realized with the tactile sensors.
