Abstract
A crash sensor for a vehicle includes: a housing defining an internal volume; a pressure sensor element disposed in the internal volume of the housing; and a membrane configured to isolate the internal volume of the housing from ambient air. The membrane is deformable for transmitting a pressure pulse indicative of a crash for detection by the pressure sensor element.
