Sensor device for detecting pressure

A pressure sensor device comprising:

• a sensing portion which comprises an elastic dielectric, a first wiring, and a second wiring, and
• a flexible printed circuit board, spaced away from the sensing portion, and the flexible printed circuit board comprises a first connection terminal and a second connection terminal, the flexible printed circuit board having a first circuit board surface and a second circuit board surface, the first circuit board surface facing in a first direction, and the second circuit board surface facing in a second direction opposite to the first direction, and the flexible printed circuit board includes a through hole that passes through the first circuit board surface and the second circuit board surface,
• wherein the first wiring is provided on a first surface of the elastic dielectric, and is connected to the first connection terminal, the first wiring to output a sensing signal, and
• wherein the second wiring is provided on a second surface of the elastic dielectric, the second surface facing in a direction away from the first surface, and the second wiring is connected to the second connection terminal, the second wiring is to output a sensing signal,
• wherein the first connection terminal is on the first circuit board surface of the flexible printed circuit board, and
• wherein the second connection terminal is on the second circuit board surface of the flexible printed circuit board,
• the first wiring is connected to the first connection terminal on the first circuit board surface, and the second wiring is connected to the second connection terminal on the second circuit board surface,
• and wherein the first wiring or the second wiring is connected to the first
• connection terminal or the second connection terminal through the through hole formed at the flexible printed circuit board between the first circuit board surface and the second circuit board surface.
