    Abstract: A system for generating electrical energy includes a thermal source, an electric field source, a stress source, a piezoelectric component, and a cycle controller coupled to the thermal source, the electric field source, and the stress source. The cycle controller provides control signals to the thermal source, the electric field source, and the stress source to repeatedly cycle the piezoelectric component through the sequence: (a) application of: a first temperature, a first electric field, and a first stress; (b) application of: the first temperature, a second electric field greater than the first electric field, and the first stress; (c) application of: a second temperature, the second electric field, and a second stress greater than the first stress; and (d) application of: the second temperature, the first electric field, and the second stress.
