Conductive ionogels with different ionic liquid contents were prepared by blending with polyurethane as the polymer network and ionic liquid (1-ethyl-3-methylimidazolium dicyandiamide, EMIM:DCA) as the conductive medium and drying into a film after blending. The ionogels were characterized using a universal testing machine, electrochemical workstation, and differential scanning calorimeter, and the results showed that the mechanical properties of the ionogels decreased and the ionic conductivity increased with the addition of EMIM:DCA content. The ionogel with 30 wt% EMIM:DCA content (WPU/IL-30) had the best overall performance with a tensile strength of 0.85 MPa, elongation at break of 264 %, ionic conductivity of 0.5 mS/cm, and excellent freezing resistance (Tg = -27.6 °C). The strain sensing performance of the ionogel was investigated using a portable sensing tester, and the results showed that the WPU/IL-30 sensor was able to regularly and stably convert the human motion state into electrical signals for transmission to the cell phone terminal, and the performances were not affected by storage time and ambient temperature. In addition, the sensing performance of the sensor remained stable after 200 cycles of 50 % stretching and had good fatigue resistance.
