Pressure sensor and microphone
First Claim
1. A pressure sensor comprising:
- a film having a surface, the film being flexible;
a first device provided at a location on the surface different from a location of a barycenter of the surface, the first device including a first magnetic layer, a second magnetic layer, and a first intermediate layer provided between the first magnetic layer and the second magnetic layer; and
a second device provided apart from the first device on the surface and provided at a location different from the location of the barycenter, the second device including a third magnetic layer, a fourth magnetic layer, and a second intermediate layer provided between the third magnetic layer and the fourth magnetic layer,a first straight line passing the first device and the barycenter being oblique with respect to the a second straight line passing the second device and the barycenter.

Abstract
According to one embodiment, a pressure sensor includes a base, and a first sensor unit. The first sensor unit includes a first transducer thin film, a first strain sensing device and a second strain sensing device. The first strain sensing device includes a first magnetic layer, a second magnetic layer, and a first intermediate layer provided between the first and the second magnetic layers. The second strain sensing device is provided apart from the first strain sensing device on the first membrane surface and provided at a location different from a location of the barycenter, the second strain sensing device including a third magnetic layer, a fourth magnetic layer, and a second intermediate layer provided between the third and the fourth magnetic layers, the first and the second intermediate layers being nonmagnetic. The first and the second strain sensing devices, and the barycenter are in a straight line.
