  • Piezoelectric element and an oscillation transducer with a piezoelectric element
    Patent number: 6897601
    Abstract: There is put forward a piezolectric element for converting pressure signals into electrical signals and vice versa, with a porous homogeneous ceramic body and with at least two electrodes attached to the ceramic body. The porous ceramic body comprises open pores and is preferably hermetically sealed on the whole surface with an elastic coating. Furthermore there is suggested an oscillation transducer with the piezolement which is accommodated in a housing. The piezolectric element is with one end face rigidly connected to the base of the housing. The other end face represents a surface which is sensitive to oscillations, which preferably is not covered by the housing. The volume of the housing is filled with a casting compound, wherein the piezolectric element is mechanically decoupled from the casting compound.
