An electrode including a conductive metal support and a paste including an electrochemically-active material and a binder. The circuit board, the power supply, and the signal emitter are accommodated in the case. The pattern-making device guides the digital marking tool with a plurality of gear teeth on an internal edge of a template frame secured to a touch-screen device using a base unit. There is also a pressure sensor that senses the pressure between the working element and the handpiece. The invention also relates to the homopolymers and copolymers obtained by homopolymerization or copolymerization of alkylidene-1,3-dioxolan-2-one monomers and to the use thereof as a component in 2K binder compositions.
