摘要: A fuel cell is used to create pressure by reverse biasing the fuel cell. A voltage is applied across the fuel cell to change the liquid near the fuel cell into gas, and expand its volume. The volume expansion is used for work function, either to expand a housing or move a piston or the like. By removing the voltage, the fuel cell can regenerate by absorbing the gas to again create energy, thereby retracting the volume expansion. In an embodiment, water may be the electrolyte which is electrolyzed to form hydrogen and oxygen gas, and then recombined into water.

摘要: A method of making carbon thin films comprises depositing a catalyst on a substrate, depositing a hydrocarbon in contact with the catalyst and pyrolyzing the hydrocarbon. A method of controlling a carbon thin film density comprises etching a cavity into a substrate, depositing a hydrocarbon into the cavity, and pyrolyzing the hydrocarbon while in the cavity to form a carbon thin film. Controlling a carbon thin film density is achieved by changing the volume of the cavity. Methods of making carbon containing patterned structures are also provided. Carbon thin films and carbon containing patterned structures can be used in NEMS, MEMS, liquid chromatography, and sensor devices.

摘要: An apparatus and method for gas-phase bromine trifluoride (BrF3) silicon isotropic room temperature etching system for both bulk and surface micromachining. The gas-phase BrF3 can be applied in a pulse mode and in a continuous flow mode. The etching rate in pulse mode is dependent on gas concentration, reaction pressure, pulse duration, pattern opening area and effective surface area.

摘要: A micromachined fluid handling device having improved properties. The valve is made of reinforced parylene. A heater heats a fluid to expand the fluid. The heater is formed on unsupported silicon nitride to reduce the power. The device can be used to form a valve or a pump. Another embodiment forms a composite silicone/parylene membrane. Another feature uses a valve seat that has concentric grooves for better sealing operation.

摘要: The present disclosure describes a Parylene micro check valve including a micromachined silicon valve seat with a roughened top surface to which a membrane cap is anchored by twist-up tethers. The micro check valve is found to exhibit low cracking pressure, high reverse pressure, low reverse flow leakage, and negligible membrane-induced flow resistance when used as a valve over a micro orifice through which flow liquid and gas fluids.

摘要: A micromachined multi-layered microbellows-style actuator capable of delivering larger deflections compared to a single layered flat membrane of comparable size. Anchor structures are disclosed that improve the strength of the microbellows membrane. A characterization apparatus is used to measure microbellows membrane performance. Thermopneumatic actuators having a resistive heater chip are also disclosed. The microbellows membrane is manufactured by alternating deposition of structural layers and sacrificial layers on a substrate. The structural layers can be made of silicon nitride and the sacrificial layers can be made of polysilicon. The substrate is etched from the back to form an opening exposing the sacrificial layers, and then the membrane is released by etching away the sacrificial layers.
