Microchip reservoir devices using wireless transmission of power and data
First Claim
1. A system for the controlled release or exposure of reservoir contents comprising:
- a microchip device comprising a substrate, a plurality of reservoirs in said substrate, reservoir contents in said reservoirs, and means for selectively controlling exposure of said reservoir contents, wherein the reservoir contents comprises a sensor which measures intrinsic electrical signals or loads on tissue structures in vivo; and
a telemetry system for the wireless transfer of data between the microchip device and a remote controller, wherein the telemetry system is adapted to transmit data from the sensor to the remote controller.

Abstract
Devices, systems, and methods are provided for wirelessly powering and/or communicating with microchip devices used for the controlled exposure and release of reservoir contents, such as drugs, reagents, and sensors. In one embodiment, the system includes (1) a microchip device comprising a substrate having a plurality of reservoirs containing reservoir contents for release or exposure; and (2) a rechargeable or on-demand power source comprising a local component which can wirelessly receive power from a remote transmitter wherein the received power can be used, directly or following transduction, to activate said release or exposure of the reservoir contents. In another embodiment, the system comprises (1) a microchip device comprising a substrate a plurality of reservoirs containing reservoir contents for release or exposure; and (2) a telemetry system for the wireless transfer of data between the microchip device and a remote controller.
