Actuation performance of the graphdiyne actuator. a Schematic for actuation mechanism of the graphdiyne actuator. Optical images show the bent actuator under 2.5 V at 0.1 Hz. b Attenuation strain of the graphdiyne actuator with increasing frequency. c Peak-to-peak displacement as a function of frequency of the three actuators. Inset is the comparison of their power densities. d Comparison of transduction efficiency of different types of actuation materials. e Cyclic stability of the graphdiyne actuator. Inset shows the actuation cycles
