Bio-Mimetic Flexible Wearable Interface with Spider-Net Coding Based On Self-Powered Triboelectric Mechanism

Abstract

A bio-mimetic flexible wearable interface is proposed with connected spider-net coding electrodes, in order to achieve single-electrode interface for various human machine interactions. Two coding approaches are investigated based on the self-generated signals of the triboelectrification between finger and friction surface of the interface. The spider-net-coding interface shows good reliability in detecting different sliding directions according to the output patterns, which is only dependent on relative amplitudes and positions of the output peaks, irrelevant of various environmental and operational parameters. In addition, it also has high capability for scale-up applications with more directions, showing great potentials in the areas of human-machine interactions, security, robotics, Internet of Things, etc.
