Abstract

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, 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.

Highlights

Patients with limb motor dysfunction caused by trauma and stroke have poor mobility to take care of themselves, which seriously affects the quality of life of them [1]
Self-powered devices based on the nanogenerators (NGs) have developed rapidly, which can help wearable sensors to get rid of the dependence on external power supplies
The NGs based on piezoelectric or triboelectric effect can convert mechanical energy into electricity directly, which have been used for self-powered sensors [10], electric skin [11], and biomedical applications [12,13,14,15]

Summary

Introduction

Patients with limb motor dysfunction caused by trauma and stroke have poor mobility to take care of themselves, which seriously affects the quality of life of them [1]. The construction of portable integrated detecting system for real-time limb motion monitoring and information interaction has considerable clinical The NGs based on piezoelectric or triboelectric effect can convert mechanical energy into electricity directly, which have been used for self-powered sensors [10], electric skin [11], and biomedical applications [12,13,14,15].
