Abstract
A piezoelectric sensitive element has elements for collecting charges appearing between the sides of the piezoelectric element. These elements include a flexible insulating strip having one the same face two distinct conductive layers each of which has an annular layer for contact with the piezoelectric sensitive element and connected by a connecting layer to a terminal layer. Application is to the detection of pinging in internal combustion engines.
