The use of touch-based technology to interact with electronic devices pre-dates modern day multi-touch technology and even the personal computer. It has recently been growing in popularity in wearable computing devices especially in the form of textile based tactile sensor. These sensors often target the detection of not only touch but also force applied. A significant problem arises here in differentiating...
This study presents our latest efforts towards developing a force sensor array by weaving 3D printed functionalized polymer fibers. Silicone was used as the base polymer and carbon fillers were used to impart electrical conductivity. Two “H”-shaped fiber cross-sections oriented orthogonally acted as a parallel plate capacitor and were used for detecting normal forces. In this article, we present the...
This paper presents our initial efforts towards the development of screen printed sensors on folded paper substrates for multi-modal sensing of biopotentials, wetness, and pressure. These sensors contain three layers of sensing stripes forming a 16-pixel array where various layers are utilized for different sensing modalities. The performance of the paper-based sensors was assessed. The sensors were...
