Simultaneous Detection of Body Movements Using Nanocomposite Multifunctional Mechanical Wearable Sensor

Year: 2025

Type: article

Abstract: ABSTRACT The field of wearable sensors, particularly motion sensors, has experienced noteworthy advancements in recent years. Motion sensors have significantly assisted doctors by gathering real‐time data and transmitting information remotely, proving highly beneficial in their practices. The sensor produced in this research is designed to withstand different kinds of mechanical forces such as tension, pressure, bending, twisting and contact. This sensor consists of a combination of silicone rubber, carbon nanotubes and carbon black, an extremely flexible composite material, and its electrodes are arranged in a spiral to provide sufficient strength under varying and strong forces. In order to capture more forces through the sensor while reducing the size of the sensor and lowering production costs, a buffer layer was created on the sensor. After data collection, the forces were separated using machine learning. The sensor was subjected to various tests and showed good characteristics (21‐225 sensitivity, 1000 cycles repeatability, 8% FSO non‐linearity, 13% FSO hysteresis, etc.). Finally, we attached the manufactured sensor to various parts of the body and were thus able to detect body movements.
