Abstract:
1. A multicellular pump comprising a plurality of pumping chambers, a deformable membrane arranged in each pumping chamber dividing each pumping chamber into a first and a second chamber section, a channel fluidly connected to said first chamber sections, a plurality of elastic energy storage means, each of said energy storage means being retained by an electrically releasable retaining mechanism in an elastically deformed state and being releasable by an electric signal to relax from said deformed state to a relaxed state, wherein releasing said energy storage means moves said membrane from a first position to a second position, thereby decreasing a volume of said first chamber section and increasing a volume of said second chamber section, wherein said first chamber sections form a reservoir, wherein each retaining mechanism is formed by an electrically releasable attachment comprising a heater, each of which is attached to one of said elastic energy storage means, wherein each electrically releasable attachment pulls each deformable membrane into an associated pumping chamber and each deformable membrane is released from the associated pumping chamber by heating said heater, and wherein each attachment comprises a heat releasable glue.
