Abstract
Strain sensor is a type of sensor that is used to measure the strain or deformation applied to an object. These sensors are widely used in engineering, scientific and industrial applications to monitor and record the deformation of an object to provide information about the forces applied. Motion Capture is a technology used to capture and record human movements, postures and actions and convert them into digital data. This technology plays a key role in industries such as gaming, movies and robotics. In recent years with the growth of these industries, there has been an increasing demand for lightweight and accurate motion capture devices, which have made wearable strain sensors for motion, capture a popular research area. This review explores wearable strain sensors for motion capture by delving into their classification and the underlying working principles. Furthermore, it will offer comprehensive insights into the primary sensing materials employed in motion capture strain sensors, coupled with a thorough analysis of the structural design aspects. Finally, a reasonable conclusion is achieved: While this type of sensors has gained significant momentum in recent years, several critical shortcomings prevent their practical application and commercialization, which are expected to be overcome soon.
