Wearable Strain Sensor Using Conductive Yarn Sewed on Clothing for Human Respiratory Monitoring

Autor: Seongcheol Ahn, Junyung Park, Yujang Cho, Jong-Jin Park, Sangki Park, Hangsik Shin

Publikováno v: IEEE Sensors Journal. 20:12628-12636

In this study, we fabricated a wearable strain sensor to monitor human respiration by lock-stitching stretchable conductive yarn onto a textile substrate. We developed the strain sensor by using conductive yarn consisting of silver-plated and unplate
