Fabric-based piezoresistive Ti3AlC2/PEDOT:PSS force sensor for wearable E-textile applications

Flexible, lightweight, and highly sensitive force sensors have broad applicability in wearable electronics, robotics, and human-machine interfaces. In this study, we present a novel fabric-based piezoresistive force sensor array based on Ti3AlC2/PEDOT:PSS nanocomposite. Fabric-based force sensors were constructed using a four layer sandwich structure with three fabrication techniques: screen-printing for electrode arrays, immersion for the sensing layer, and pressing for assembling the force sensor arrays. The fabricated force sensor exhibits an ultrahigh sensitivity up to 1.51 N-1. The fabric-based piezoresistive Ti3AlC2/PEDOT:PSS force sensor shows a wide force detection range of 0-200 N and fast response and recovery times of 0.4 s and 0.08 s, respectively. This study opens up new possibilities for the development of smart textiles and advanced wearable technologies that could revolutionize various industries.
