摘要： An electrokinetic high pressure hydraulic pump for manipulating fluids in capillary-based systems includes (i) a microchannel having a fluid inlet and outlet and a porous dielectric material disposed in said microchannel; (ii) an electrolyte contained within said microchannel and in communication with the porous dielectric material; (iii) spaced apart electrodes that are in contact with said electrolyte; and (iv) means for applying an electric potential to said spaced apart electrodes. The pump, which requires no moving mechanical parts, uses electro-osmotic flow to generate high pressures for pumping and/or compressing fluids, for providing valve means and means for opening and closing valves, for controlling fluid flow rate, and for manipulating fluid flow particularly in capillary-based systems. The compact nature of the high pressure hydraulic pump permits construction of a micro-scale or capillary-based HPLC system that fulfills the desire for small sample quantity, low solvent consumption, improved efficiency, running parallel samples and field portability. Control of pressure and solvent flow rate are achieved by controlling the voltage applied to the electrokinetic pump.

摘要： The invention exploits a widely used device in micro-fluidics, the electro-osmotic pump (EOP), to create very low energy micro-scale and macro-scale mechanical actuators. The EOP uses electrical fields to move naturally occurring charged particles (ions) through a fluid medium. As the ions move in response to the applied field, they drag the (non-charged) fluid along, establishing bulk flow. When confined to a narrow chamber, a pressure gradient can be established. The combination of pressure gradient and flow performs mechanical work. With the use of electro-osmotic pumps, the invention enables actuators to be constructed in a variety of embodiments, including for example, a sheet structure, a piston structure, and a cellular structure to name a few.

摘要： An electrochemical direct heat to electricity converter includes a primary thermal energy source; a working fluid; an electrochemical cell comprising at least one membrane electrode assembly including a first porous electrode, a second porous electrode and at least one membrane, wherein the at least one membrane is sandwiched between the first and second porous electrodes and is a conductor of ions of the working fluid; an energy storage reservoir; and an external load. The electrochemical cell operates on heat to produce electricity. When thermal energy available from the primary thermal energy source is greater than necessary to meet demands of the external load, excess energy is stored in the energy storage reservoir, and when the thermal energy available from the primary thermal energy source is insufficient to meet the demands of the external load, at least a portion of the excess energy stored in the energy storage reservoir is used to supply power to the external load.
