Abstract
A measuring tape device may include a housing having an aperture, a reel assembly, a blade, and a piezoelectric bimorph layer. The reel assembly may be enclosed within the housing, and may be configured to alternately allow the blade to be withdrawn from the reel assembly through the aperture or received in the aperture onto the reel assembly. The blade may have a first end configured to extend from the housing through the aperture and a second end configured to be wound on the reel assembly. The piezoelectric bimorph layer may be disposed over at least a portion of the blade.
