Conducting Yarn based Capacitive Humidity Sensor

Increasing demand for wearable sensors for multipurpose applications have made it an essential part of our everyday life. In such a scenario; reusability, flexibility, cost effectiveness, and integrability of such sensors are among the top desirable features. Using our casual clothing as sensors can be one of the most effective ways for various therapeutic, diagnostic, and continuous monitoring functionalities. Conducting yarns, possibly, have the capability to deeply influence the 4th industrial revolution and rule the e-textile based smart wearables for wide range applications. Herein, we present a comparative experimental study of three different capacitive sensor structures for humidity sensing applications. These structures have been explored using conducting yarns having tungsten metal as core conducting materials.
