Abstract: An assembly (10) for converting mechanical work into electrical energy comprising a bending transducer (12) with a support (20) in the form of a strip and with at least one piezoelectric layer (22) attached thereto, the support (20) in the form of a strip being mounted at both ends (30) and an actuating mechanism (8, 30) being provided in such a way that, when the actuating mechanism (8, 30) is actuated, a mechanical force is exerted on the support (20) in the longitudinal direction of the support (26) and leads to arcuate bending of the bending transducer (12), and thereby to the generation of electrical energy. The assembly can be used to provide electrical energy for a counting device.

Abstract: A metering device (2) comprises an energy generation unit (12) for generating comparatively small amounts of energy during an operating cycle; an energy storage unit (24, 26) for buffering the amount of energy generated; a control unit (14) for determining an item of current state information (I); and a processing unit (16) for processing the current state information (I) further, wherein the energy requirement of the control unit (14) and the energy requirement of the display unit (16) are different, and the allocation of the limited amount of energy for the control unit (14) and the processing unit (16) is regulated according to the different energy requirement.
