Abstract
A sensor configured to detect a stress wave propagating through a vehicle frame member caused by a vehicle collision is provided. The sensor includes a sensor body configured to be rigidly coupled to the vehicle frame member, a first strain sensing device and a second strain sensing device attached to the sensor body. The sensor body is configured to exhibit stress in response to transverse and torsional stress wave propagating along the vehicle frame member. The first strain sensing device generates a first signal indicative of stress in the sensor body and the second strain sensing device generates a second signal indicative of stress in the sensor body. A first end portion of the sensor body is characterized as trapezoidal prism shaped and a second end portion of the sensor body is characterized as trapezoidal prism shaped.
