简介
Artificial tactile sensors aim to mimic human touch with high sensitivity, fine spatial resolution, low detection thresholds, and fast response. However, developing a human‐like haptic system that integrates crosstalk‐free large‐scale arrays, ultra‐low power consumption, and efficient signal transmission and interpretation remains a formidable challenge. Inspired by human skin's layered structure and neural pathways, we developed a skin‐like optical fiber tactile sensor. A finger‐like multilayer composite is integrated onto the endsurface of a dense optical fiber array. Using self‐powered mechanoluminescent (ML) materials, this tactile photonic skin visualizes mechanical stimuli in real time, bridging tactile sensing and visual perception. Each optical fiber independently transmits localized luminescent signals, ensuring crosstalk‐free, high‐fidelity spatial encoding. Coupled with an area‐array CMOS imager and vision …
