Abstract With the increasing demand for advanced biomedical technologies, there is a pressing need flexible, integrated systems capable of simultaneously detecting and stimulating biological processes with high precision reliability. In this study, an on‐chip flexible electronic system successfully fabricated that combines both photoelectric detection stimulation functionalities. This integrates single‐crystal silicon nanomembrane (Si‐NM) photodiode array micro‐all‐inorganic light‐emitting diodes (µ‐ILEDs), achieving comprehensive flexibility complete encapsulation. The Si‐NM exhibits broad responsivity across visible light spectrum. Observed spatial response variations enable detector to accurately capture information, precisely determining position direction sources. Notably, incorporates ultrathin thermally grown dioxide (t‐SiO 2 ) biofluid barrier. barrier ensures stable leakage current in device following 120 h immersion 90 °C PBS solution, guaranteeing long‐term stability Furthermore, effectively prevents infiltration toxic elements into surrounding tissues, ensuring safety biocompatibility implant. By leveraging materials manufacturing not only enhances performance optoelectronic devices but also expands their application scope field, opening new avenues future research clinical innovations.
