Abstract: The merging of humans and machines depends on the contact sensor medium used. However, this contact interaction inevitably leads to mechanical loss. Photodetectors are cutting-edge tools in optical communication that use controlled lighting to achieve efficient signal conversion to drive mechano-optical communication systems and provide an innovative interface for the Internet of Things services. Here, a self-powered, non-contact mechano-optical communication system based on a wearable Te@TeSe photodetector textile is presented, which encodes near-infrared light to modulate robotic manipulator actions. The wearable Te@TeSe photodetector textile enhanced the photocurrent and responsivity by 400 times compared to a pristine Te nanowire (NW) array. The type II heterojunction of Te@TeSe NWs is proved by first-principles calculations and simulated, providing insights on photogenic carrier transmission in Te@TeSe NWs. This system shows the possibility of duplicate real-time execution of mechanical gestures in virtual environments and paves the way for advanced optical devices applied to information transmission and mechano-optical communication.
