Abstract:
1. A piezoelectric security system for monitoring a selected area, said piezoelectric security system comprising: a plurality of piezoelectric cables positioned along the selected area, said plurality of piezoelectric cables defining a plurality of unique combinations, each of said plurality of unique combinations defining a zone, each of said plurality of piezoelectric cables producing an electrical signal in response to a mechanical force; a processor in communication with said plurality of piezoelectric cables, said processor responsive to each said electrical signal produced by said plurality of piezoelectric cables, said processor detecting an intrusion event when at least one electrical signal is received, said processor identifying said zone based on receipt of a plurality of electric signals corresponding to one of said plurality of unique combinations of piezoelectric cables, said processor producing an alert signal in response to said intrusion event, said alert signal containing information including at least said zone; and a communication device for communicating said alert signal.
