PRESSURE SENSOR, MICROPHONE, AND ACOUSTIC PROCESSING SYSTEM

摘要

According to one embodiment, a pressure sensor includes: a base body; a sensor section; and a processing circuit. The sensor section includes: a transducing thin film; a first strain sensing element; and a second strain sensing element. The transducing thin film has a film surface and is flexible. The processing circuit is configured to output as an output signal at least one of a first signal obtained from the first strain sensing element upon application of external pressure to the transducing thin film and a second signal obtained from the second strain sensing element upon application of the external pressure to the transducing thin film.
