Abstract

Wearable and stretchable strain sensors have received much attention because of their easy interaction with the human body. They are widely used in many fields, such as healthcare monitoring and human motion detection. Recent advances in the design and implementation of wearable and stretchable strain sensors and their application prospects are summarized herein. The research on sensitive strain sensors will be introduced herein first, which mainly involves the application of nanomaterials in the strain sensor. The remarkable properties of nanomaterials enable the carbon nanotube sensor to be embedded in socks, gloves, bandages, and other items that can be attached to the human body to accurately monitor various movements of the human body, including training, breathing, typing, and speaking. And then, we will focus on the application prospects of wearable strain sensors. With the development of the Times and the progress of science and technology, wearable strain sensors are gradually applied to various fields, especially in intelligent medical treatment, sports and fitness, and entertainment. Although the research on wearable strain sensor has produced considerable progress so far, it is still in the prototype stage, and wearable strain sensor still faces significant challenges in manufacturing a multi-functional integrated strain sensor. The research of this paper will be of great value to the study and application of wearable strain sensors.
