Chemical Vapor Deposited Graphene/PDMS based Flexible Strain Sensor for Human Motion Detection Application

This study presents the development and characterization of a flexible Graphene/PDMS-based strain sensor for human motion detection applications. The sensor is fabricated using chemical vapor deposited (CVD) graphene onto a Polydimethylsiloxane (PDMS) substrate. The proposed sensor offers a promising solution for capturing and quantifying the complex deformations associated with human movements. The strain-induced changes in the graphene’s electrical conductivity are monitored and correlated with the applied mechanical strain. The sensor exhibits excellent sensitivity, repeatability, and linearity, making it suitable for accurate and reliable human motion detection. The proposed strain sensor holds great promise for various human-centric applications. Its integration into wearable devices or clothing could provide real-time monitoring of body movements and posture, enabling applications in sports performance analysis, health monitoring, and rehabilitation.
