Abstract

A method may include placing a first device on a first side of a skin portion of a subject and transferring a material through the skin portion of the subject from the first device to a subdermal second device disposed on a second side of the skin portion of the subject.

Claims

1. A device, comprising:

a reservoir configured for placement externally to a skin portion of a subject;

an output port operably connected to the reservoir and configured for transferring a liquid material therethrough, the liquid material in direct contact with the skin portion of the subject under force, utilizing at least one of an electric field, a microjet, or an ultra fine stream, to an input port of a second device placed on a second side of the skin portion of the subject; and

a receiver configured for receiving a signal from the second device.

2. The device of claim 1, further comprising:

a second port configured for transferring a second liquid material therethrough, the second liquid material in direct contact with the skin portion of the subject to the second device.

3. The device of claim 2, wherein the second port is operably connected to the reservoir and configured for transferring the liquid material therethough, the liquid material in direct contact with the skin portion of the subject to the input port of the second device.

4. The device of claim 2, wherein the second port is operably connected to a second reservoir and configured for transferring the second liquid material therethrough, the second liquid material in direct contact with the skin portion of the subject.

5. The device of claim 1, wherein the signal comprises:

at least one of an electrical current, an electrical field, a magnetic flux, an optical signal, a radio frequency identification, or an ultrasonic signal.

6. The device of claim 1, wherein the signal comprises:

a signal regarding at least one of a need for the liquid material, a need for a quantity of the liquid material, a need for a type of the liquid material, a location, cessation of a need for the liquid material, a quantity of the liquid material collected, or a ready condition for receiving the liquid material.

7. The device of claim 1, further comprising:

a transmitter configured for transmitting a signal to the second device.

8. The device of claim 7, wherein the signal comprises:

a signal regarding at least one of a location, a desire to transfer material, a readiness to transfer material, a characteristic of the material to be transferred, an amount of material available to be transferred, a time for transfer to commence, an amount of material to be transferred, a desire to stop transfer, or an acknowledgement that transfer is complete.

9. The device of claim 1, further comprising:

a sensor configured for detecting an indicator of the location of the second device.

10. The device of claim 9, wherein the indicator of the location of the second device comprises:

a fiducial on the subject.

11. The device of claim 9, wherein the indicator of the location of the second device comprises:

a fiducial on the second device.

12. A device, comprising:

a reservoir configured for placement externally to a skin portion of a subject;

an output port operably connected to the reservoir and configured for transferring a liquid material therethrough, the liquid material in direct contact with the skin portion of the subject under force, utilizing at least one of an electric field, a microjet, or an ultra fine stream, to an input port of a second device placed on a second side of the skin portion of the subject; and

a sensor configured for detecting an indicator of the location of the second device.
