Abstract:
1. A microbattery, comprising: a plurality of layers of elements that interact with one another to produce an electrical current; a plurality of propellant members, each of which is formed of a phase-change material; an initiator means; a plurality of conductors, each conductor of said plurality of conductors providing electrical communication between a preselected propellant member of said plurality of propellant members and said initiator means; a pressure cell defining a closed volume for housing said plurality of propellant members; a fluidic oscillator mounted on said pressure cell; a flexible diaphragm mounted to said fluidic oscillator, said flexible diaphragm adapted to oscillate as said fluid oscillator alternately directs fluid to opposite sides of said flexible diaphragm; a magnetic core mounted to said flexible diaphragm; a cap layer mounted in surmounting relation to said flexible diaphragm; a coil mounted to said cap layer, said coil adapted to receive said magnetic core; whereby a preselected propellant is activated by said initiator means; whereby explosion of said preselected propellant increases pressure within said pressure cell; whereby said pressure is harnessed to drive said fluidic oscillator; whereby said fluidic oscillator causes flow of a preselected fluid to alternately flow to opposite sides of said flexible diaphragm so that said flexible diaphragm oscillates and thereby causes back-and-forth motion of said magnetic core relative to said coil; whereby alternating current is produced by the relative motion between said magnetic core and said coil.
