Abstract
A method of manufacturing a piezoelectric beam is provided. The method includes inserting a piezoelectric body and a pair of roller pins into an injection molding form. Once the piezoelectric body and roller pins are enclosed within the injection mold form a liquefied substance is injected into the injection molding form. The liquefied substance solidifies to substantially permanently affix the roller pins to opposing distal ends of the body.

18. A method of manufacturing a plurality of piezoelectric bimorph beam, said method comprising:
-
affixing a pair of piezoelectric wafers to opposing surfaces of a flexible substrate to form a piezoelectric bimorph slab; subdividing the piezoelectric bimorph slab by cutting into a plurality of piezoelectric bimorph bars, each said bimorph bar constituting a bimorph body of a respective piezoelectric bimorph beam to be manufactured; inserting one of the piezoelectric bodies into an injection molding form; inserting a pair of roller pins into the injection molding form; injecting a liquefied substance into the injection molding form to affix the roller pins to opposing distal ends of the body; and duplicating inserting one of the piezoelectric bodies into an injection molding form, inserting a pair of roller pins into the injection molding form and injecting a liquefied substance into the injection molding form to affix the roller pins to opposing distal ends of the body for each of the piezoelectric bimorph bodies. - View Dependent Claims (19, 20, 21, 22)
