方案详情

Electrochemical actuators directly converting electrical energy to mechanical energy are
critically important for artificial intelligence. However, their energy transduction efficiency is
always lower than 1.0% because electrode materials lack active units in microstructure, and
their assembly systems can hardly express the intrinsic properties. Here, we report a
molecular-scale active graphdiyne-based electrochemical actuator with a high electromechanical transduction efficiency of up to 6.03%, exceeding that of the best-known piezoelectric ceramic, shape memory alloy and electroactive polymer reported before, and its
energy density (11.5 kJm−3) is comparable to that of mammalian skeletal muscle (~8 kJm−3).
Meanwhile, the actuator remains responsive at frequencies from 0.1 to 30 Hz with excellent
cycling stability over 100,000 cycles. Furthermore, we verify the alkene–alkyne complex
transition effect responsible for the high performance through in situ sum frequency generation spectroscopy. This discovery sheds light on our understanding of actuation
mechanisms and will accelerate development of smart actuators.
