Claim Text:
1. A method of manufacturing an ultrasonic horn for a high power actuator, comprising the steps of: forming a monolithic pre-stress portion constructed from a first material, said monolithic pre-stress portion having a first interior surface and a second interior surface defined therein, said first interior surface and said second interior surface connected by at least one flexure, said first interior surface, said second interior surface and said configured to provide a pre-stress cavity for a high power actuator material, said at least one flexure configured to apply a pre-stress that varies by less than one part in a hundred as a temperature varies over 100 degrees Celsius to an actuator material inserted in said pre-stress cavity; and forming a horn portion connected to said monolithic pre-stress portion, said horn portion configured to be driven at a resonance frequency.
