Claim 10:
11. A gas detector comprising:
a membrane configured to define a sensing chamber of the gas detector, the sensing chamber comprising a relaxed state pressure;
a moving body operatively connected to one or more walls of the membrane, the moving body configured to apply one or more or more forces on the one or more walls of the membrane, wherein applying the force causes a volume change inside the sensing chamber;
a pressure sensor configured for measuring pressure change inside the sensing chamber, the pressure change being caused by the volume change; and
a controller operatively connected to the pressure sensor and the moving body, the controller configured to:
determine a rate of return to the relaxed state pressure inside the chamber; and
determine a condition of the membrane based on the determined rate of return to the relaxed state pressure.
