Abstract: An energy harvesting system for footwear is described having a sole, heel and an upper and comprising a first gaseous bellows pump formed at the sole of the footwear with the bellows hinged forward of the sole; a second gaseous bellows pump formed at the heel of the footwear with the bellows hinged forward of the heel. A gas reservoir is mounted to the upper of the footwear in fluid communication with first and second gaseous pumps downstream of the pumps and adapted to receive the gaseous medium exiting under pressure from the pumps. An axial turbine has an output shaft mounted on the footwear upper downstream of the reservoir and adapted to receive pressurized gas from the reservoir when a predetermined pressure threshold is attained in the reservoir so as to activate the axial turbine; and an electrical generator mounted on the upper, downstream of the axial turbine and engaged with the turbine output shaft which can be engaged only when a predetermined shaft velocity threshold has been attained.

Abstract: A fluid pump (10) has a compression member (12) having a variably-sized compression surface (13b) movable against fluid pressure in a chamber (22). The effective surface area of the compression member (12) decreases in size together with a corresponding cross-sectional area of the chamber (22) from a maximal area at a beginning of the compression stroke to a minimal area at the end of the compression stroke. Using a variably-sized surface area to compress a fluid volume allows obtaining a rapid gain of fluid pressure even for applications in which the compression member (12) is actuated at relatively low frequencies and under the action of relatively small forces.
