Abstract: Embodiments of a 3D micro-battery structure are disclosed. The 3D micro-battery structure includes an electrode micro-structure and a thin film electrolyte. The electrode micro-structure includes a base and a group of electrodes extending from the base. The thin film electrolyte conformally coats each of the group of electrodes to form a group of coated electrodes, such that the thin film electrolyte is ionically conducting and is electrically insulating.

Abstract: A microstructured surface with microfeatures formed thereon and defining spaces between the microfeatures includes least one electrode of an electrode pair in the spaces, wherein electrodes of the pair are electrically connected to one another. The at least one electrode located in the space is configured to generate a gas in between the microfeatures when an electrolyte solution penetrates into the microfeatures. Importantly, the electrodes are not connected to any external power source. Because the microstructured surface is self-powered in replenishing the gas lost in a submerged condition, no additional provision to supply energy or regulate the replenishment is necessary for implementation and use.

Abstract: A superhydrophobic surface includes a plurality of microfeatures disposed on a substrate and a gas generator disposed within the microfeatures, the gas generator configured to generate a gas within the microfeatures. Gas is generated within the microfeatures when at least a portion of the microfeatures is in a wetted state to restore the microfeatures to a dewetted state. Gas generation is self-regulating in that gas generation automatically starts when a wetted condition exists and stops when sufficient gas has been generated to recover a dewetted state that restores superhydrophobicity.

Abstract: A low-profile shear-sensing unit includes a floating plate surrounded by a frame and a displacement sensor that measures in-plane movement of the floating plate. Covered with a surface sample, the floating plate is displaced by the friction drag (i.e., shear) on the surface caused by the flow of fluid and the in-plane displacement is measured by the displacement sensor. The shear force on the sample surface is then obtained by multiplying the measured displacement and the spring constant of the flexure beams, which suspend the floating plate. The floating plate and the flexure beams are formed out of one plate or substrate to achieve monolithic construction with a beam geometry that leads to a high-resolution measurement.

Abstract: A method of fluid manipulation involves applying electric signals at one or more electrodes located on or adjacent to a surface in contact with a liquid that contains a surfactant. The electric field generated by the electric signals (e.g., biasing voltage) applied to the electrodes makes the liquid less wetting on the surface than the natural state and can be used to move or modify the shape of the liquid droplet placed on the surface. One embodiment makes a liquid dewet locally on a surface by applying electric signals locally on the surface so that the liquid can be electrically manipulated on a hydrophilic surface.

Abstract: Disclosed is a microbattery having a substrate with a surface that includes an array of posts extending from the surface of the substrate to form a first electrode. An selectively-cured electrolyte forms a conformal coating over the surface of the substrate and the array of posts to provide a coated electrode. A second electrode substantially encases the coated electrode.

Abstract: A fuel cell is disclosed with a self-regulated oxygen supply used in conjunction with a self-pumping fuel supply (e.g., a self-pumping anode). The cathode side of the fuel cell includes a gas diffusion electrode interposed between the fuel chamber and the oxidant chamber (e.g., H2O2), the gas diffusion electrode having a catalyst layer formed thereon. An oxygen gas capturing substrate is disposed in the oxidant chamber and is spaced apart from the gas diffusion electrode. The gas capturing substrate has first and second sides containing a plurality of holes extending there between. The first side of the substrate faces the oxidant and the second side faces the gas diffusion electrode. The substrate contains a catalyst on the second side of the substrate or within an inner surface of the holes.
