Electrohydrodynamic receptor
First Claim
Patent Images
1. 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.

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.

1. 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. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14)

15. 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. - View Dependent Claims (16, 17, 18, 19)

20. 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. - View Dependent Claims (21, 22, 23, 24, 25)

26. 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. - View Dependent Claims (27, 28)
