Artificial Tactile Sensing System Based on Triboelectric Nanogenerator and Synaptic Transistor

Artificial tactile sensing system could realize the perception of different types of tactile information. Nowadays, most tactile sensors mainly convert the external stimulation signals into different material conductivity value, and processed by complex external circuits to detect the human physiological signals. In this work, the artificial synaptic device was connected with triboelectric nanogenerator(TENG) to fabricate a tactile sensing system in a simple way. This system could detect the external pressure stimulations and accurately recognize small frequency touch signals of <inline-formula> <tex-math notation="LaTeX">$1-2.5$ </tex-math></inline-formula> Hz. In addition, the complex biological behavior was also simulated, which enlightened significance for the future bionic tactile systems and the field of human-computer interaction.
