Design a Touch Sensor Using Conductive Spandex Fabric

Recent advancements in sensor technology have propelled the e-textile industry to the forefront of innovation. E-textiles, also known as smart fabrics, possess physical and dimensional flexibility, making them suitable for wearable sensor technology. These technologies are developed to cater to the needs of advanced daily life, which aligns with the IoT development trend. This paper introduces an applied resistive sensor that uses an electronic fabric made from elastic fabric and carbon nanotubes (CNTs) fabric as the electrical layer. The sensor achieves high sensitivity (2.6241 N−1 with force less than 1 N), thickness (~3 mm), and versatility make it ideal for load performance and fast resistance switching without waiting for capacitor charging and discharging as capacitive sensors, facilitating faster interaction with e-touch. The study provides an overview of the sensor's characteristics and future directions, emphasizing the creation of soft sensors based on pyralux for medical devices and health monitoring applications in the future.
