Piezoelectric snap actuator |
摘要 |
A piezoelectric actuator including a piezoelectric element; a snap-action device for exerting a positive force in opposition to the piezoelectric element and having a predetermined reaction force that must be overcome to cause the snap action; the piezoelectric element including piezoelectric means for providing an opposing force to the snap-action device in excess of the reaction force; and means for applying an electric field to the piezoelectric means to enable it to generate the opposing force and store energy in the snap-action device to enable occurrence of the snap action.
