Abstract

However, its robustness and endurance are seriously challenged by frequent and inevitable mechanical impacts during operation. Herein, we demonstrate, for the first time, a fully self-healing TENG possessing the ability to recover its performance after damage by introducing healable polymer materials and electrodes consisting of small magnets into the device. Our works imply that high-performance self-healing TENG can be readily realized attributed to not only the excellent mechanical-healing capability of the employed healable polymer but also the quick electric-healing capability of the novel magnetic-assisted electrodes designed for the TENG. The measurements indicate that both the output voltage and current of the healed device can reach up to above 95% of their original values even after the 5th breakage-healing cycle. Additionally, the presented TENG also shows shape-tailorability and object-adaptability. This maximizes the effective contact area of device and further increases the electric output performance to benefit energy harvesting and self-powered sensing of versatile mechanical motions. This research will offer feasible strategies for developing novel mechanical energy harvesting devices and self-powered sensors with recoverability, robustness and adaption.
