A bioinspired self-powered optical tactile sensing system with ultrahigh sensitivity and ultralow detection limit.

ABSTRACT: High-sensitivity tactile perception is vital for precise robotic operations in human-machine interactions (HMI). Currently, state-of-the-art tactile perception relies on electrical sensors which demand complex circuits and decoding components, leading to increased energy consumption and susceptibility to electromagnetic interference. Hence, the utilization of human-perceptible signals, such as visible light, as the transmission medium is necessary. Inspired by the mechano-electro-optical transduction mechanism in dinoflagellate bioluminescence, here we propose a self-powered optical tactile sensing system (SOTS) for converting the electrical signal of pressure sensing into visible luminescent intensity, thereby enabling the wireless transmission and visualization of tactile information.
