An apparatus providing mechanical-to-electrical energy conversion generates electrical current by moving a conductive fluid in the presence of magnetic field. The motion of the fluid is induced by a mechanical energy source and the generated electrical current is directed to a useful load. The proposed apparatus utilizes a conductive fluid as a 'liquid rotor' has substantially different radial velocity distribution than the conventional, prior art solid rotor. The apparatus includes an inverter, controlled by the flow of the conductive fluid, to generate a train of pulses as an output, where the pulses are used by an associated transformer to provide an AC output voltage.

Mechanical energy harvesting utilizing liquid rotor homopolar generator

A method of mechanical-to-electrical energy conversion utilizes a mechanical spring in combination with a rapid-action variable inductance magnetic flux switch to convert a spring-loaded mechanical energy into a change in magnetic flux captured by an electrical coil element within the magnetic flux switch. The change in coil inductance and magnetic flux induces a current to flow through the electrical coil in the form of a a pulse of electrical energy that may be stored. The electrical coil is coupled to the mechanical spring so that each time the spring is released, the coil moves with respect to a magnetic core and a change in flux is created. The application of an external mechanical force (such as human locomotion) functions to compress and subsequently 'unlock' the mechanical switch, allowing for the electrical energy associated with the application of aperiodic forces to be harvested.

A method and apparatus for generating thermal energy (heat) from human locomotion is proposed and used to provide heating of the user's footwear. The apparatus takes the form of a pair of flexible, liquid-filled chambers connected by an energy-generating tube. One chamber is located in the heel region of a footwear insole, with the other in the toe region, such that as a person walks, the liquid moves back and forth within the tube. This movement is used to also move an energy-producing element (either an electromagnetic arrangement or viscous liquid) back and forth within the tube and convert the captured human locomotion energy into thermal energy, thus warming the footwear.

A device comprising a substrate having a surface that comprises a conductive base layer. The device also comprises fluid-support-structures on the conductive base layer. Each of the fluid-support-structures has at least one dimension of about 1 millimeter or less. Each of the fluid-support-structures is coated with an electrical insulator. The device is configured to oscillate a fluid locatable between tops of the fluid-support-structures and the conductive base layer when a voltage is applied between the conductive base layer and the fluid.

Fluid oscillations on structured surfaces

A method and apparatus is disclosed wherein the movement of a droplet disposed on a nanostructured or microstructured surface is determined by at least one characteristic of the nanostructure feature pattern or at least one characteristic of the droplet. In one embodiment, the movement of the droplet is laterally determined by at least one characteristic of the nanostructure feature pattern such that the droplet moves in a desired direction along a nanostructured feature pattern. In another embodiment, the movement of the droplet is determined by either at least one characteristic of the nanostructure feature pattern or at least one characteristic of the droplet in a way such that the droplet penetrates the feature pattern at a desired area and becomes substantially immobile.

A closed-loop apparatus for converting mechanical energy into electrical energy utilizes a closed-loop channel including sections of different cross-section (including a first group of sections having a constrained cross-section and a second group sections having an enlarged cross-section). An energy-producing configuration (such as coils and/or electrodes) is formed to surround at least a portion of the channel. A closed-loop chain of energy-producing elements is positioned in channel such that when the chain moves along the channel, the mechanical motion generates electrical energy. The chain is formed to include a set of expandable assemblies that change in dimension as they pass through the different cross-section areas of the channel. An inert fluid is injected into the channel at one or more locations by a mechanical force, resulting in the creation of a pressure-induced force differential that initiates and maintains the movement of the chain with respect to the channel.

Apparatus for closed-loop mechanical energy harvesting

An energy harvesting apparatus is described that utilizes hydraulic actuation and creates a continuous, revolving motion of a chain of energy-producing elements within an energy-producing channel (the channel being in the form of a tube, for example). In particular, the arrangement of the present invention is based upon a specially-designed dual-loop channel topology that allows for efficient conversion of a unidirectional flow of a fluid entering the energy-producing channel into a smooth, continuous revolving motion of a chain of energy-producing elements within the channel.

An energy harvesting system for converting mechanical energy into electrical energy uses an electrostatic arrangement based upon the interaction between conductive microfluidic droplets and dielectric-coated electrodes in combination with an electromagnetic arrangement based upon the interaction between magnetic elements and coils, with the two arrangements disposed in an interleaved configuration that provides a degree of synergy to the overall system in the form of providing spacings between adjacent elements and providing a bias voltage source for the electrostatic arrangement from the energy created by the electromagnetic arrangement.

Method and apparatus for mechanical energy harvesting using combined magnetic and microfluidic energy generation

An energy harvesting apparatus utilizes a modular structure to preserve the proper alignment between a chain of energy-producing elements and an energy-producing channel (within which the chain is located and free to slide along, creating electrical energy from mechanical movement). The channel includes a plurality of rigid modules that are separated by flexible segments of tubing. The rigid channel modules house the energy-producing electrodes and/or coils. The chain includes a plurality of rigid modules that are attached along a flexible string in a spaced-apart configuration. The rigid chain modules house the energy-producing magnets and/or conductive droplets. The combination of the flexible channel segments and chain string allow for freedom of motion of the apparatus (required for human locomotion, for example), while providing the desired 'fixed' alignment between the rigid energy-producing modules.

An apparatus comprising a mechanical-to-electrical energy converting device utilizes an array of microfluidic droplets in association with a planar electrode and separated by a dielectric layer to form a capacitive structure. An elastic spacer is also disposed between the planar electrode and array of droplets, such that as the spacer is compressed, the contact area of the droplets and the dielectric is increased&#x2014;increasing the total capacitance value. Periodic changes in the force applied to the elastic spacer (such as associated with vibrational motion) creates a periodic change in the capacitance value, generating an electrical current flow between the planar electrode and array of conductive droplets.

An apparatus includes a substrate having a top surface, a substantially regular array of raised structures located over the top surface, and a layer located on the top surface between the structures. Distal surfaces of the structures are farther from the top surface than remaining portions of the structures. The layer is able to contract such that the distal surfaces of the structures protrude through the layer. The layer is able to swell such that the distal surfaces of the structures are closer to the top surface of the substrate than one surface of the layer.

Another apparatus comprises at least one disk rotatably located over a substrate and in a well of the substrate, the disk having an outer circumference with teeth thereon. The disk is positioned to provide a maximum distance of less than about 10 microns between each one the teeth and a nearest wall defining the well. The substrate includes a channel with an exit port located near the teeth of the disk.
