Human skin continuously acquires information from its surroundings prior to physical contact. Replicating such pre-touch perception in mechanically compliant electronic systems remains a significant challenge. In this talk, I will present an ultrathin multispectral photonic skin that integrates near-infrared organic photodetectors and mid-wave infrared black-phosphorus photodetectors on a common flexible platform. By combining optical proximity sensing and thermal-radiation detection, the system enables simultaneous acquisition of spatial and thermal information before contact. I will discuss the device architecture, multimodal sensing demonstrations on a humanoid hand, and the broader potential of multispectral photonic skins for future embodied, wearable, and robotic systems.
