Introduction

George C. Kirby, III is an accomplished inventor based in Alexandria, VA. He has made significant contributions to the field of actuator technology, particularly through his innovative patent. His work focuses on enhancing the performance and reliability of piezoelectric actuators.

Latest Patents

Kirby holds a patent for "Actuators with graded activity." This invention presents a method for reducing and/or shifting stress in at least one outer end portion of an actuator made from piezoelectric material. The actuator is affixed to a substrate by an adhesive bond and is designed to cycle between expanded and contracted positions, which creates stresses in both the actuator and the bond. The method involves doping at least one outer portion of the actuator with a metal oxide to reduce piezoelectric activity. In a preferred embodiment, the doped outer portion has a gradient composition that varies from maximum concentration at the end of the actuator to essentially zero concentration at a point inward of the end. The system includes a doped piezoelectric actuator that is adhesively bonded to a substrate, with electrodes attached to the actuator for receiving electrical energy.
