Sensor
First Claim
1. A sensor, comprising:
- a first film;
a first sensor portion provided at the first film, the first sensor portion includinga first magnetic layer,a second magnetic layer provided between the first film and the first magnetic layer, anda first intermediate layer provided between the first magnetic layer and the second magnetic layer;
a driving portion configured to cause the first film to deform at a first frequency; and
a processor configured to output a third signal based on a first signal and a second signal, the first signal being supplied by the processor and relating to the first frequency, the second signal being output from the first sensor portion,whereinthe second signal is a signal modulated by the deforming of the first film, andthe processor outputs the third signal by demodulating the second signal.

Abstract
According to one embodiment, a sensor includes a first film, a first sensor portion, a driving portion, and a processor. The first sensor portion is provided at the first film. The first sensor portion includes a first magnetic layer, a second magnetic layer, and a first intermediate layer. The second magnetic layer is provided between the first film and the first magnetic layer. The first intermediate layer is provided between the first magnetic layer and the second magnetic layer. The driving portion causes the first film to deform at a first frequency. The processor outputs a third signal based on a first signal and a second signal. The first signal relates to the first frequency. The second signal is output from the first sensor portion.
