Piezoelectric sensor and method of fabrication a piezoelectric device

摘要

The piezoelectric component i.e. piezoelectric sensor (1), has an electrically conductive contact layer (4) partially arranged between a piezoceramic layer (2) and another piezoceramic layer (3), where the contact layer is joined between the former piezoceramic layer and the latter piezoceramic layer by a joining material (9) by applying pressure to the former piezoceramic layer against the latter piezoceramic layer, where the joining material is based on silver or a silver compound and silver alloy. The joining material is connected with the contact layer by sintering. An independent claim is also included for a method for manufacturing a piezoelectric sensor.
