摘要
A stress-wave sensor module, a stress-wave sensor, and a method for detecting a vehicle collision event utilizing the stress-wave sensor are provided. The stress-wave sensor has first and second support members and a diaphragm member coupled between the first and second support members. The stress-wave sensor further has first and second strain gauge sensors coupled to both the first support member and the diaphragm member. The first and second strain gauge sensors generate first and second signals, respectively, in response to the first and second strain gauge sensors detecting deflection of the diaphragm member due to stress waves propagating through the diaphragm member.
