First, 145 cycles of the cyclic test were performed at an electric field strength of 10 V μm−1 at a frequency of 0.5 Hz for a PUA, b PUA–PEGDA-5, c PUA–PEGDA-10, and d PUA–PEGDA-15. The approximate drift distance after 145 cycles is stated in red. Profile of a single cycle of e the strain response of PUA and PUA–PEGDA-15 under a 10 V μm−1 electric field at 0.1 Hz is shown to demonstrate the difference in response time, t0.9. This response time t0.9 represents the time for the actuator to reach 90% of its maximum displacement at 0.1 Hz. f Response time t0.9 at various PEGDA concentrations (0, 5, 10, and 15 wt%)
