Title
Conductive textile element embedded in a wearable device for joint motion monitoring
Abstract
Wearable strain sensors potentially hold great significance in several areas, such as rehabilitation, research, sports. Conductive textile elements are excellent candidates for the development of wearable devices as human motion capture systems because of their intrinsic properties of lightweight, compliance, flexibility, and stretchability. Herein, the metrological characterization of sensing elements based on a conductive textile intended for joint motion monitoring is presented.The aim of this study is twofold: (i) analyzing the influence of the shape on the metrological properties of conductive textiles, (ii) providing a preliminary assessment of the performance of a custom-made wearable device (i.e., a glove) embedding a conductive textile element to monitor wrist joint movements. The static characterization and the hysteresis analysis were performed on two samples of conductive textile elements, i.e., the zig-zag pattern and the rectangular one. The feasibility assessment of a glove embedding one sensing element for wrist flexion-extension monitoring was performed on a single volunteer.Results showed that the zig-zag patterned conductive element had a resistance change range comparable to the rectangular one (i.e., 100 kΩ – 170 kΩ vs. 40 kΩ – 80 kΩ), higher averaged sensitivity (i.e., -3.96 kΩ•%-1 vs. -2.42 kΩ•%-1), and a lower hysteresis error, 6.83%). the % (i.e., averaged 5.22% vs. Regarding feasibility assessment of %the wearable device, results showed good performance in tracking wrist flexion-extension in real-time. The proposed wearable device embedding a conductive textile element seems to be suitable for wrist motions monitoring with promising applications in contexts as rehabilitation, sports, and clinical research.
