PRESSURE SENSOR, MICROPHONE, BLOOD PRESSURE SENSOR, TOUCH PANEL, PRESSURE SENSOR MANUFACTURING METHOD, AND PRESSURE SENSOR MANUFACTURING DEVICE
Document Type and Number:
Japanese Patent JP2015064255
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pressure sensor, a microphone, a blood pressure sensor, a touch panel, a pressure sensor manufacturing method, and a pressure sensor manufacturing device which are capable of improving sensitivity.SOLUTION: According to an embodiment, a pressure sensor is provided equipped with a support part, a circuit board, and a plurality of detection elements. The circuit board is supported by the support part and is deformable. The detection elements are provided on part of the circuit board. The detection elements have a first magnetic layer, a second magnetic layer, and an intermediate layer. The magnetization of the first magnetic layer changes in accordance with the deformation of the circuit board. The magnetization of the second magnetic layer is fixed. The intermediate layer is provided between the first magnetic layer and the second magnetic layer. The direction of magnetization in the second magnetic layer of a first detection element among the plurality of detection elements is different from the direction of magnetization in the second magnetic layer of a second detection element among the plurality of detection elements.
