1. A method of verifying the operation of an accelerometer that includes a piezo element, said method comprising:

  • channeling a high frequency signal from an output of a signal source to the piezo element through a positive lead that is electrically coupled to the piezo element; and

    at an input of a monitoring device, detecting a signal from a negative lead that is electrically coupled to the piezo element, wherein, if the detected signal from the negative lead is substantially similar to the high frequency signal channeled through the positive lead, the integrity of the accelerometer is verified.
