PRESSURE SENSOR, PRESSURE SENSOR SYSTEM, MICROPHONE, BLOOD PRESSURE SENSOR, AND TOUCH PANEL

Japanese Patent JP2017146237

A

PROBLEM TO BE SOLVED: To provide a pressure sensor with higher sensitivity.SOLUTION: The pressure sensor according to an embodiment includes a film part, a first sensor part, and a first structure. The film part has a surface and can be deformed. The first sensor part is fixed to a part of a surface separate from a first part of an outer edge of the surface. The first sensor part includes a plurality of first sensing elements. The plurality of first sensing elements includes a first magnetic layer, a first opposite magnetic layer, and a first non-magnetic intermediate layer. The first structure is disposed beside the first sensor part along the direction where the plurality of first sensing elements is arranged. The first structure includes a first structure layer, a first opposite structure layer, and a first intermediate structure layer. The first structure layer has at least one of the potential that is the same as the potential of the first opposite structure layer and the floating potential relative to the first opposite structure layer.SELECTED DRAWING: Figure 1
