Abstract (en)
[origin: WO2012166777A2] A cosmetic applicator includes bristles or tines with selectively changeable durometer to allow the relative flexibility or stiffness to be adjusted by the user. The bristles or tines are made directly from or incorporate within their structure piezoelectric ceramic fibers. The relative flexibility or stiffness of the piezoelectric fibers can be adjusted by subjecting the fibers to an electric current, or an electric or magnetic field, to cause the fibers to gain or lose flexibility. Stiffness or softness of the applicator can thus be adjusted to be suitable for different application operations such as depositing cosmetic product or combing and clump removal.
