Forearm Movement Detection using Carbon based Composite Film
Abstract - In this research, a bracelet type wearable sensor was developed using PET polymer film with carbon based conductive layer. The mechanism of surface resistance variation of the composite film employed in this study was the relationship between the variations of surface resistance and the width variations of crack gaps in the conductive layer occur when the film was bent, resulted in the width of crack gaps significantly affect the resistance variation of conductive layer. The fabricated bracelet-type wearable sensor using the polymer film successfully detected the intention of forearm movement, wrist flexion and finger flexion, without using complex pattern recognition algorithm.
