An Artificial Tactile Perception System with Spatio-Temporal Recognition Capability (Adv. Mater. Technol. 20/2024)

Abstract

Artificial Tactile Perception Systems

In article number 2400338, Tingting Zhao, Jianhua Zhang, an co-workers present an artificial tactile perception system capable of sensing, encoding, and learning spatio-temporal information of pressure stimuli. It combines piezoelectric nanogenerators and a multiple-gate synaptic transistor for sensing and processing. Exploiting the modulation capability of the gate electrode positioned variably relative to the channel on the proton migration, the spatial position and time sequence of the applied pressure can be distinguished.
