ABSTRACT:
A piezoelectric transformer comprises a piezoelectric substrate extending in a first direction, a first electrode structure provided on the substrate for exciting an elastic wave propagating through the substrate in the first direction as a result of the piezoelectric transverse effect, and a second electrode structure provided on the substrate for converting the elastic wave to an electric voltage, wherein the first electrode group occupies a first area on the substrate while the second electrode group occupies a second area on the substrate.
