a Schematic of the device structure. b Thermoelectric (TE) sensing mechanism of ReCLEAR devices. c Triboelectric (TENG) sensing mechanism of ReCLEAR devices. d Real-time TE voltage outputs of pristine, self-healed, and recycled ReCLEAR hydrogels during temperature cycling (10 to 60 °C) using Peltier heating, creating –8 °C to +5 °C temperature difference across electrodes. e Extracted thermal voltages from the curves in (d). f TENG responses of pristine, self-healed, and recycled ReCLEAR hydrogels under 10 N applied force. g TE-dominated long-press sensing mechanism (H: hold; R: release). h TENG-dominated short-press sensing mechanism (T: tap; R: release). Input intensity: long press: 3–5 N at 27–28 °C; short press: 1–2 N at 24–25 °C.
