X-T flexure piezoelectric device

An elongated piezoelectric bar, having only one of its axes rotated relative to the crystallographic axes of the piezoelectric material, with electrodes fixedly positioned on each of four opposed major surfaces thereof to produce flexure of the bar in a plane through the length and width of the bar....

Beschreibung
Zusammenfassung:	An elongated piezoelectric bar, having only one of its axes rotated relative to the crystallographic axes of the piezoelectric material, with electrodes fixedly positioned on each of four opposed major surfaces thereof to produce flexure of the bar in a plane through the length and width of the bar. The bar is constructed with the width or frequency dependent transverse dimension greater than the thickness of frequency independent transverse dimension.
