Abstract
An electrohydrodynamic (EHD) receptor that incorporates microchannels and reservoir(s) for selectively dispensing fluid from the reservoir(s) to a specific location, e.g., onto the surface of the receptor.
Claims28
A receptor comprising:
- a substrate having an exterior surface;
- a reservoir in said substrate carrying a stored fluid;
- a microchannel in said substrate having a first end coupled to said reservoir and a second end coupled to said exterior of said substrate;
- and
- an electrohydrodynamic (EHD) micropump having a pair of electrodes coupled to said microchannel so that responsive to a control signal said stored fluid will flow to a location on the exterior surface of the substrate.
2 more elements
A receptor comprising:
- a substrate;
- a plurality of reservoirs in said substrate carrying one or more types of stored fluids;
- one or more microchannels each coupled at a first end to one of said plurality of reservoirs and each coupled at a second end to a surface of said substrate;
- and
- a plurality of electrohydrodynamic (EHD) micropumps, where each of said plurality of EHD micropumps has a pair of electrodes coupled to one of said microchannels so that responsive to one or more control signals, one or more types of said stored fluids will flow to a specific location on the surface of the substrate.
2 more elements
A method of fabricating a receptor, said method comprising the steps of:
- (a) forming a reservoir on a substrate for storing a fluid;
- (b) forming on said substrate a microchannel coupled at a first end to said reservoir and coupled at a second end to a surface of said substrate;
- and
- (c) forming an electrohydrodynamic (EHD) micropump having a pair of electrodes coupled to said microchannel so that responsive to a control signal, said stored fluid with flow to a specific location on the surface of the substrate.
1 more element
A system for moving fluids, said system comprising:
- a receptor having a reservoir in a substrate;
- a microchannel coupled at a first end to said reservoir and coupled at a second end coupled to an exterior surface of said substrate;
- an electrohydrodynamic (EHD) micropump having a pair of electrodes coupled to said microchannel;
- and
- a station coupled to said receptor, where said station sends a control signal to said EHD micropump, where said EHD micropump, responsive to said control signal, causes a stored fluid in said reservoir to flow to a location on said exterior surface of the substrate.
