1. A small scale electrical generator, comprising:

  • a. an elongated substrate;

    b. a first piezoelectric fine wire disposed along a surface of the substrate, the first piezoelectric fine wire having a first end and a spaced-apart second end; and

    c. a first conductive contact securing the first end of the fine wire to a first portion of the substrate and a second conductive contact securing the second end of the fine wire to a second portion of the substrate, wherein at least one of the first conductive contact and the second conductive contact including a material that exhibits a band gap with respect to the first piezoelectric fine wire so as to form a Schottky barrier therebetween.
