MetadataShow full item record
Provided is a light activated piezoelectric converter comprising a cantilever vane coupled to a foundation. The vane comprises a first surface and a second surface. The first and second surfaces are generally co-planer and adjacent to a common boundary and have differing emissivities. A piezoelectric material is additionally coupled to the vane, arranged such that a deflection of the free end of the vane generates stress acting on the piezoelectric material. When the piezoelectric converter is illuminated with a radiant flux, the differing emissivities of the first and second surfaces produce a temperature gradient across the vane and a thermal creep force across the planar surface generates a deflection of the vane, and a subsequent voltage induced by the stress on the piezoelectric material generates a voltage between a first electrode and second electrode in electrical contact with the piezoelectric material.
