Abstract
In robotics and AI-based systems, there is a demand for sensors with efficient and targeted multifunctionalities. The emergence of triboelectric sensors presents avenues to meet these demands. This study introduces an approach by integrating smart thermosensitive triboelectric nanosensors into a robotic platform, which facilitates material recognition through the contact electrification process. Equipped with self-powered tactile awareness, the robotic fingers provide accurate material identification through the “touch and sense” mechanism. The sensor features micropyramidal structures in Ecoflex-based encapsulation layers, with NaCl solution as the electrolyte conductor. This configuration enhances stretchability and sustains sensitivity. Moreover, due to the multifunctional sensing capability of the self-powered thermosensitive sensors, this can be utilized in bionic prosthesis systems as receptors. The integration of robotics with self-powered thermosensitive sensors can be employed as cost-effective automated sensing, aiding material identification.
