Signal and power transfer to actuators distributed on conductive fabric sheet for wearable tactile display

Abstract

We propose a scheme to implement a wearable tactile display with distributed actuators using a “two-dimensional signal transmission sheet (2DST sheet)”. This device provides tactile feedback by driving actuators placed on 2DST sheet. We can drive these actuators without individual wiring from a driver circuit to each actuator. Physical mounting and electrical connection of actuators are integrated into a single action, i.e., sticking a “pin badge connecter” into the 2DST sheet. In this paper, we present a 2DST-based power transfer system capable of supplying electricity selectively to each actuator placed on the 2DST sheet and of controlling each power.
