Abstract:
A composite piezoelectric material, manufacturing of the composite material and use of this composite material in piezoelectric components are disclosed. More particularly, a piezoelectric thick film materials or piezoelectric paint being a composite piezoelectric material including piezoelectric particles randomly dispersed within a polymer matrix are disclosed. A paste of composite piezoelectric material including a matrix of polymer having a relative permittivity ≥3, normally ≥6, sintered piezoelectric particles having a relative permittivity in the range of 100-5000, normally in the range of 400-1000 and an average particle size between 1 and 50 μm, although the particles should be smaller than 1/10 of the final thickness of the final layer of piezoelectric material, and additives such as dispersing agents or thinner are disclosed where the final paste has a 0-3 connectivity pattern, a content of sintered piezoelectric particles between 15 and 75 vol %, normally between 40 and 60 vol %.
