Development of a Highly Sensitive Wearable Tactile Sensor on Fabric by Using Conductive Inks Based on Electrical Contact Resistance (ECR) Change Mechanism

A wearable tactile device, based on the electrical contact resistance (ECR) between the two fabric substrates, is developed in this work for continuous health monitoring. Microscale pillar structures are formed over top and bottom fabric substrates by screen‐printing technique with conductive inks followed by the face‐to‐face assembly of top and bottom parts. The contact areas between the substrates increase after the application of an external...
