Self‐Powered High‐Resolution and Pressure‐Sensitive Triboelectric Sensor Matrix for Real‐Time Tactile Mapping

A triboelectric sensor matrix (TESM) can accurately track and map 2D tactile sensing. A self‐powered, high‐resolution, pressure‐sensitive, flexible and durable TESM with 16 × 16 pixels is fabricated for the fast detection of single‐point and multi‐point touching. Using cross‐locating technology, a cross‐type TESM with 32 × 20 pixels is developed for more rapid tactile mapping, which significantly reduces the addressing lines from m × n to m + n .
