Self-Powered Tactile Sensor for Gesture Recognition Using Deep Learning Algorithms.

A multifunctional wearable tactile sensor assisted by deep learning algorithms is developed, which can realize the functions of gesture recognition and interaction. This tactile sensor is the fusion of a triboelectric nanogenerator and piezoelectric nanogenerator to construct a hybrid self-powered sensor with a higher power density and sensibility. The power generation performance is characterized with an open-circuit voltage of 200 V, a short-circuit current of 8 μA, and a power density of 0.
