Abstract
A sensor system comprising two or more electrically-independent piezoelectric cables, secure at intervals to a common rigid or semi-rigid structure or to themselves and spaced apart from one another, with one cable at any given instant coupled to an electrical drive signal and acting as a transmitter, the other cable or cables acting as a receiver and connected to electronic detection circuitry, such that a mechanical vibration signal is launched by the transmitter and detected by the receiver to enable the detection function of the other cable or cables as receivers to be checked.
