Abstract:
An electronic switch (400) comprises a substrate (402) having a surface (416) and an embedded electrode (404), a droplet (410) of conductive liquid located over the embedded electrode (404), and a power source (414) configured to create an electric circuit including the droplet (410) of conductive liquid. The surface (416) comprises a feature (482) that determines a contact angle between the surface (416) and the droplet (410).
Abstract:
A switch (400) comprises a first switch element (300) configured to actuate by electrowetting, the first switch element (300) comprising at least two radio frequency contacts (318, 322) and at least two control electrodes (306, 308). The switch (400) also comprises at least two additional switch elements (410, 420) configured to make and break an electrical connection between the at least two control electrodes (306, 308) of the first switch element (300).
Abstract:
A varactor (10) includes a container (18) forming a liquid chamber (20), a first electrode (14) mounted adjacent the chamber (20), and a second electrode (16) mounted adjacent the chamber (20). The chamber (20) may be sized and configured, and a spacing between the electrodes (14, 16) and the chamber (20) may be selected, so that a contact angle of a quantity of liquid metal (12) in the chamber (20) relative to at least one of the electrodes (14, 16) can be changed by applying a bias voltage.
Abstract:
A switch (100) comprises an input contact (121) and at least one output contact (122), a single droplet (130) of conductive liquid located in a channel (120), the droplet (130) being in constant contact with the input contact (121), and a heater (104) configured to heat a gas (135). The heated gas expands to cause the droplet (130) to translate through the channel (120).
Abstract:
An electronic switch (300) comprises a droplet (310) of conductive liquid located in contact with a surface (312) having an alterable surface configuration, an input contact (324) located on the alterable surface and configured such that the input contact (324) is in constant electrical contact with the droplet (310), and a micro-electronic mechanical system (MEMS) (304) for altering the surface configuration to change the contact angle of the droplet (310) with respect to the surface (312).
Abstract:
A micro-machined nozzle includes a substrate (12) having a hole (14) formed on a first side (12a) that extends partially through a thickness dimension of the substrate (12) and a nozzle orifice (16) formed on a second opposite side (12b) that communicates with the hole (14). The nozzle orifice (16) has at least a portion of its interior wall serrated. A method of fabricating a micro-machined nozzle includes the steps of etching a first side (12a) of a silicon substrate (12) to form a hole (14) that extends partially through a thickness dimension of the substrate (12) and etching a second opposite side (12b) of the silicon substrate (12) to form a serrated nozzle orifice (16) that communicates with the hole (14).
