a Schematic design, enabling biodegradable electronics for fully recyclable devices. b Chemical reaction responsible for triggering transience. c PVA-based, electrical degradation performance in various solvents. d PCL-based, electrical degradation in various solvents and e stability in different pH solutions. Degradation vs. time images in PBS (pH 7.4) of the f PVA and (scale bar, 3 mm) g PCL-based resistor (scale bar, 3 mm). SEM of metal-PCL interface: h before degradation and i after 6 weeks soaked in PBS (7.4 pH) at 37 °C (scale bar 10 µm).
