Abstract
Aspects of the subject technology relate to an apparatus having a housing, including a port exposed to an environment. The apparatus includes a pressure sensor disposed within the housing to measure a pressure of the environment. The pressure sensor includes a membrane to facilitate detection of a presence of an aggressor by using dynamic response analysis.
Claims20
An apparatus comprising:
- a housing including a port exposed to an environment;
- and
- a pressure sensor disposed within the housing and configured to measure a pressure of the environment,
- wherein the pressure sensor includes a membrane configured to facilitate detection of a presence of an aggressor by using a dynamic response analysis, wherein the membrane includes two or more electrodes configured to sense and actuate respectively to facilitate the dynamic response analysis.
