a Schematic of the overall AJP strategy for LM patterning and sensor fabrication. PVP and DEG denote polyvinylpyrrolidone and diethylene glycol, respectively. b AJP printing of LM patterns on various substrates, including glass slides, silicon wafers, polyimide (PI) films, paper, plant leaves, nitrile gloves, polydimethylsiloxane (PDMS) films, and 3 M tapes (scale bar: 2 mm). The experiment was repeated independently three times with similar results. c Comparison of patterning resolution and the ratio of sensing range-to-detection limit (εemax/εemin) among various stretchable strain sensors. Source data are provided as a Source data file.
