Pressure-labelled tactile perception in robotics enabled by a skin-inspired dual-mode triboelectric sensor and neural networks

Kequan Xia, Song Yang, Dong Qiang, Oli Prendergast et autres

—Artificial intelligence (AI) enabled biomedical robots rely on tactile perception, but tactile sensing is limited by force induced variability that mixes material signals with contact pressure. Here, we introduce a pressure-labelled tactile intelligence framework built on a bioinspired tactile sensor (BT sensor) …
