    摘要: A method of fabricating a needle via conformal deposition in a two-piece mold includes the step of attaching a top mold member to a bottom mold member such that the top mold member and the bottom mold member define an enclosed, elongated needle trench with a deposition aperture. A conformal substance, such as polysilicon, is then passed through the deposition aperture such that the conformal substance is deposited within the enclosed, elongated needle trench to form a needle. The method is used to form needles with prongs, multiple channels, multiple ports, barbs, strength enhancement features, and circuitry.

    摘要: An implantable electrode and method for manufacturing the electrode wherein the electrode has a strong, adherent surface coating of iridium oxide or titanium nitride on a platinum surface, which demonstrates an increase in surface area of at least five times when compared to smooth platinum of the same geometry. The iridium oxide coating may be formed on platinum by a physical deposition process, such as sputtering. The process of electroplating the iridium oxide surface coating is accomplished by voltage control processes. A gradient coating of iridium oxide ranging in composition from essentially pure platinum to essentially pure iridium oxide is produced by sputtering.

    摘要: A microfabricated valve includes a substrate with a fluid path. A main cantilever is positionable in a resting closed state to prevent fluid movement through the fluid path and a resting open state that allows fluid movement through the fluid path. A ratchet cantilever supports the main cantilever in either the resting closed state or the resting open state, such that the main cantilever does not have to be energized to maintain the resting closed state or the resting open state. A valve state transition mechanism selectively energizes the main cantilever or the ratchet cantilever during a valve state transition period to selectively transition between the resting open and closed states.
