Button - Ironed Embossed Fabric

What does the sensor do?

It can be used as a on-off buttons. Resting state: circuit open ; push down: circuit close.

How it works?

The coated fabric surface is conductive - so when two electrods are placed beneath it, it can be used to sense whether it is connected by coated fabrics (whether the fabric is pushed down). And the ironed embossed fabric can always return to its original shape (unconnected) when the pushing force is removed.

You will need:

• carbon black ink and polyurethane
• ironed embossed fabric
• conductive silver fabric

Sensor structure & Fabrication steps

• Laser cut ironed embossed fabrics.
• Dip-coat fabrics with carbon black ink and then polyurethane.
• Connect with silver fabric segments.
