Transparent stretchable wearable hybrid nano-generators present great opportunities in motion sensing, motion monitoring, and human-computer interaction. Herein, we report a piezoelectric-triboelectric sport sensor (PTSS) which is composed of TENG, PENG, and a flexible transparent stretchable self-healing hydrogel electrode. The piezoelectric effect and the triboelectric effect are coupled by a contact separation mode. According to this effect, the PTSS shows a wide monitoring range. It can be used to monitor human multi-dimensional motions such as bend, twist, and rotate motions, including the screw pull motion of table tennis and the 301C skill of diving. In addition, the flexible transparent stretchable self-healing hydrogel is used as the electrode, which can meet most of the motion and sensing requirements and presents the characteristics of high flexibility, high transparency, high stretchability, and self-healing behavior. The whole sensing system can transmit signals through Bluetooth devices. The flexible, transparent, and stretchable wearable hybrid nanogenerator can be used as a wearable motion monitoring sensor, which provides a new strategy for the sports field, motion monitoring, and human-computer interaction.
透明可拉伸可穿戴混合纳米发电机在运动传感、运动监测和人机交互方面展现出巨大机遇。在此，我们报道了一种压电摩擦电运动传感器（PTSS），它由摩擦纳米发电机（TENG）、压电纳米发电机（PENG）和柔性透明可拉伸自愈合水凝胶电极组成。压电效应和摩擦电效应通过接触分离模式耦合。基于这种效应，PTSS具有广泛的监测范围。它可用于监测人体的多维运动，如弯曲、扭转和旋转运动，包括乒乓球的拧拉动作和跳水的301C技术动作。此外，柔性透明可拉伸自愈合水凝胶用作电极，能满足大部分运动和传感需求，并呈现出高柔韧性、高透明度、高拉伸性和自愈合性能。整个传感系统可通过蓝牙设备传输信号。这种柔性、透明且可拉伸的可穿戴混合纳米发电机可作为可穿戴运动监测传感器，为体育领域、运动监测和人机交互提供了一种新策略。
