Abstract
A displacement-generating battery cell for driving a drug-delivery device is described. The cell may include at least one volume-changing element. The cell may include a housing formed according to a concertina-shaped design with folds in the walls thereof and may contain an internal chemical reaction system. The chemical reaction system may include an electrode. The electrode may be the volume-changing element. The arrangement of said chemical reaction system may be such that an expansion of the volume-changing element in a direction lengthens the cell and thus reduces the extent of the folds. Drug-delivery devices including the displacement-generating battery cell are also described.
