Abstract
Devices, systems, and methods are provided for applying a cosmetic design to a biological subject. An applicator array device may include a substrate. The applicator array device may include a plurality of applicator elements disposed on the substrate, together defining an applicator array. Each applicator element may include a first electrode, an electroactive polymer layer disposed on the first electrode, and a second electrode, disposed on the electroactive polymer layer. The applicator array device may also include an applicator surface overlying the applicator array. Each applicator element may be configured to switch between a first position and a second position upon application of a voltage to the first electrode or the second electrode, or upon removal of the voltage from the first electrode or the second electrode.
