a Principle of the ACEL mPDT device. This sandwiched ACEL mPDT device includes the hydrogel electrode layer (top), emissive layer (middle), and PS hydrogel electrode layer (bottom), and it connects to the power through electronic conductor. Under the AC electric field, the emissive layer emits green electroluminescence, and then activates PS to generate 1O2. b Photographs of the ACEL mPDT device (left: side view; right: top view). c SEM micromorphology and EDS element surface distribution of the emissive layer. d Schematic diagram of the origami-inspired TENG. e Cross-sectional view of the FEP/Cu/PI/Cu/FEP layered structure. Green, yellow, and purple respectively represents FEP, Cu, and PI. f Preparation process of the TENG. g Photographs of the TENG at initial, compressed, and stretched state. h Demonstration model of the TENG-driven ACEL mPDT device. The TENG embedded in the shoes through energy harvesting can drive this ACEL mPDT device to emit green electroluminescence.
