Fig. 5. Sensing performance and practical application of the CLiPS device.

Fig. 5

a Pressure response of the original and self-healed films under a static pressure condition (1 V applied bias @ 100 Hz). b Pressure sensitivity comparison between CLiPS and CLPU@E0-IL (insert, black) (used as a reference), applied bias of 100 mV at 20 Hz. c Relative change in capacitance plots as a function of the applied pressures (0.08 kPa, 0.2 kPa, 0.5 kPa, and 2.1 kPa) with respect to time (applied bias voltage of 100 V at 100 Hz). d Mechanical durability test results of the CLiPS-based sensor (250 cycles), applied bias at 100 mV at 100 Hz). e Transient response time of the CLiPS piezocapacitive sensor at a loading pressure of 90 Pa. The insert represents a response time of 260 ms and a reset time of 270 ms. f Comparison between CLiPS-based sensor and previously reported autonomous self-healing iontronic pressure sensors in terms of autonomous capability, sensitivity, modulus, self-healing efficiency, and stretchability. Red, black, blue, green, dark-blue, violet, and turquoise colors correspond to this work, ref. 40, ref. 32, ref. 38, ref. 52, ref. 53, and ref. 33, respectively (see detail on Supplementary Table 5). g, h Photographs showing LED brightness before and after applied pressure of the CLiPS-based device (left) and the CLPU@E0-IL-based device (right).
