Wearable devices play an important role in our daily life. We can use it in the sports area and the medical area. This review uses many articles to introduce how to use different sensors to analyze human kinetic characteristics. This review is divided into three parts. In the first sections, we will introduce the working principle and its calculation method of the different sensors such as IMUs sensors, pressure transducers, etc. The second part will show you some research about using wearable sensors to calculate the joint data and link the data with human movement. These researches can help us stay far away from joint diseases. In conclusion, we give some suggestions about the improvement of wearable devices.
