Emerging Nanogenerators for Rehabilitation Monitoring and Information Interaction

Soft wearable devices with flexibility and stretchability attract thousands of researchers around the world. These devices can be used in health monitoring, intelligent robotic and rehabilitation training system. Emerging nanogenerators (NGs) have been studied extensively for soft wearable devices due to the advantages of easy fabrication, cost-effective, self-powered and high sensitivity in response to mechanics stimulus. Recently, the scientists have developed a flexible and stretchable nanogenerator for rehabilitation monitoring and information interaction, which is called FSDM-NG and emphasized in this commentary. The piezoelectric and triboelectric effects of the FSDM-NG have been utilized for different functions, showing some interesting and useful results to be acted as a self-powered limb motion sensor and an interface of information interaction. The purpose of the commentary is to discuss the characteristics and perspectives of NGs as self-powered wearable sensors and information interaction devices in biomedical field.
