Abstract
A digital material in the form of a composite consisting of particles of porous ferroelectric ceramics and a polymer matrix with the inclusion of metal particles was obtained. The properties of this material, as well as the properties of the polymer-metal matrix, were investigated. It is shown that this matrix has a high local conductivity. This provides electrical contact between the particles of porous piezoceramics, which is the main factor that ensures the presence of piezoelectric properties in this composite.
