Summary: In this study, a self-powered bionic antenna (SBA) was developed to mimic the structure and function of insect antenna for robotic tactile sensing. The SBA uses a triboelectric nanogenerator technology to convert mechanical stimuli into voltage signal without the need for external power source, and can identify different contact materials. To imitate the active sensing performance of insect antenna, a two-stage actuator was integrated into the SBA, enabling active sensing in both horizontal and vertical planes. The lightweight and drivable design of SBA makes it highly compatible with micro soft robots and a promising solution for future robotic tactile systems.

Summary: In the era of IoTs, triboelectric nano-generators (TENGs) are widely researched for self-powered sensing due to their high efficiency, versatile configuration, and low cost. However, the inherent variation of TENG outputs limits their direct use as primary sensing signals. To solve this issue, a new method is proposed to extract the sensing signal that is independent of TENG output variations. This method accurately determines applied strain using the ratio of currents in two parallel branches, eliminating the effect of output variations and providing a self-powered sensing solution.
