PIEZOELECTRIC SENSOR COMPRISING AT LEAST ONE PAIR OF FLEXIBLE SENSITIVE ELEMENTS OF LARGE LENGTH

摘要

P Piezoelectric sensor comprising at least one pair of long flexible sensitive elements whose respective electrodes are connected in parallel. The interconnection is performed by intersecting the sensitive elements so that the two electrodes of each of them are alternately in electrical contact with the two electrodes of at least one other sensitive element. The sensor can be made by winding at least one pair of sensitive elements on a support 4 according to two cross-directional inverted propellers. The chosen mounting mode ensures both a good mechanical strength and simplifies the electrical connections because of the multiple electrical contacts between the electrodes. / P P Application to the realization of hydrophones for example. / P
