Figure 5

Thermosensitive performance and application of poly(ionic liquid) hydrogel. (a) Relative current changes at different temperatures. (b) The relative current changes in a temperature gradient of 5-70°C. (c) Instantaneous electrical response of the sensor to hot (45°C) and cold (35°C) source. (d) Performance of multiple stimulations of pressure and temperature. (e, f) The current changes during body fever and antipyretic process, and the inset pictures correspond to a simulated body fever.
