Near infrared-interactive synaptic display enabling neuromorphic photothermal applications

Human-interactive displays (HIDs) have advanced the ability to visualize a spectrum of phenomena, ranging from tangible to imperceptible. Within the realm of HIDs, the role of infrared technologies stands out, with applications spanning from imaging to biomedicine. Here, we introduce a novel near infrared (NIR)-interactive synaptic display based on alternating current electroluminescence (ACEL), with a unique near infrared-responsive layer comprising from a blend of MXene and a polymer electrolyte. Our synaptic display transcends mere responsiveness to NIR exposure, by leveraging synaptic properties to visualize NIR exposure, thereby successfully realizing a neuromorphic display. Utilizing this system, we present an intelligent wound healing device through neuromorphic photothermal therapy, demonstrating its potential as a personalized treatment device. Moreover, we demonstrate the potential of this display in visualizing infrared radiation, highlighting its promising role in the ever-evolving field of HIDs.
