Double layer wiring on fabric using soft polyurethane film substrate and its application to motion capture devices

E-textiles technology, which incorporates sensors on fabric, is expected to have a variety of applications. We propose a two-layer structure using a soft polyurethane film substrate to realize a soft substrate that does not restrict movement and a two-layer wiring for wiring integration. As evaluation tests of the two-layer wiring, the interlayer insulation resistance, the resistance of the interlayer connections is measured, and conducted static and dynamic bending tests to investigate whether the proposed structure meets the required specifications of the inertial sensor to be used. We also reproduced the posture of the device on Unity using the created sensor device.
