Abstract
A sensor device has an insulative non-woven fabric and a conductive fabric forming an electrode. The conductive fabric is joined to one surface of the non-woven fabric by at least one of fusion and seaming.
Claims19
A sensor device comprising:
- an insulative non-woven fabric;
- a first conductive fabric forming an electrode, the first conductive fabric being provided on a first surface of the insulative non-woven fabric, the first conductive fabric being joined to the first surface of the insulative non-woven fabric at a first joining portion by at least one of fusion and seaming;
- and
- a second conductive fabric facing the first conductive fabric with the insulative non-woven fabric interposed therebetween, the second conductive fabric being joined to a second surface of the insulative non-woven fabric at a second joining portion by at least one of fusion and seaming,
- wherein the first joining portion is disposed along substantially an entire outer periphery of the first conductive fabric, and the second joining portion is disposed along substantially an entire outer periphery of the second conductive fabric, such that the first joining portion and the second joining portion being displaced from each other in a plan view of the sensor device, and that the second joining portion substantially surrounds outer edges of the first conductive fabric in the plan view,
- wherein the insulative non-woven fabric includes a first extension and a second extension extending from a side thereof in the plan view,
- and wherein the first conductive fabric includes a first extending portion joined to the first extension, and the second conductive fabric includes a second extending portion joined to the second extension.

A sensor device comprising:
- a first insulative non-woven fabric;
- a first conductive fabric forming an electrode, the first conductive fabric being provided on and joined to a first surface of the first insulative non-woven fabric at a first joining portion by at least one of fusion and seaming;
- a second insulative non-woven fabric overlaid on a second surface of the first insulative non-woven fabric;
- and
- a second conductive fabric facing the first conductive fabric with the first insulative non-woven fabric and the second insulative non-woven fabric interposed therebetween, the second conductive fabric being joined to a first surface of the second insulative non-woven fabric adjacent to the second conductive fabric at a second joining portion by at least one of fusion and seaming, the second joining portion substantially surrounding the outer edges of the first conductive fabric in a plan view of the sensor device,
- wherein the first insulative non-woven fabric and the second insulative non-woven fabric are joined together at a third joining portion by at least one of fusion and seaming, the third joining portion being positioned outside of an area in which the first conductive fabric and the second conductive fabric are disposed, such that the third joining portion substantially surrounds outer edges of the first and second conductive fabrics in the plan view,
- wherein the first insulative non-woven fabric includes a first extension, and the second insulative non-woven fabric includes a second extension which does not overlap the first extension in the plan view,
- and wherein the first conductive fabric includes a first extending portion joined to the first extension, and the second conductive fabric includes a second extending portion joined to the second extension.
