A vehicle wiper assembly includes a wiper blade having a length, and an active material disposed along the length of the wiper blade and coupled thereto. The active material includes a shape memory alloy material with a crystallographic phase that is changeable between austenite and martensite, and is elastically deformable and operatively applies a spring force against a portion of the wiper blade when the crystallographic phase is martensite.
