Abstract
A method of generating electrical energy in an integrated circuit that may include setting into motion a (3D) three-dimensional enclosed space in the integrated circuit. The 3D enclosed space may include a piezoelectric element and a free moving object therein. The method may also include producing the electrical energy from impact between the free moving object and the piezoelectric element during the motion.
Claims27
A method of generating electrical energy in an integrated circuit, the method comprising:
- setting into relative motion at least one enclosed space in the integrated circuit and at least one free moving object housed in the at least one enclosed space, the integrated circuit comprising at least one piezoelectric element within the at least one enclosed space, the integrated circuit comprising a plurality of layers defining the at least one enclosed space within the plurality of layers;
- producing the electrical energy from impact between the at least one free moving object and the at least one piezoelectric element during the relative motion;
- and
- transmitting the electrical energy via a plurality of conductive traces in the integrated circuit.
