Abstract

Embodiments of a system including a remotely controlled reaction device and associated controller are described. Methods of use and control of the device are also disclosed. According to various embodiments, a reaction device is placed in an environment in order to perform a chemical reaction in an environment. Exemplary environments include a body of an organism, a body of water, or an enclosed volume of a fluid. In selected embodiments, a magnetic field, an electric field, or electromagnetic control signal may be used.

Claims

1. A reaction system comprising:

a body structure adapted for positioning in an environment;

a reaction region located in or on the body structure, the reaction region including a first material configured to influence a chemical reaction at the reaction region; and

a remotely activatable control element operably coupled to the body structure and responsive to an electromagnetic field control signal to modify one or more of the rate or kinetics of the chemical reaction, the remotely activatable control element including at least one of a valve element or a structural element, wherein the remotely activatable control element includes a polymer and a magnetically or electrically active component.

2. The reaction system of claim 1, wherein the remotely activatable control element includes a valve element responsive to a change in at least one dimension of the remotely activatable control element.

3. The reaction system of claim 1, wherein the magnetically or electrically active component is configured to be heated or cooled responsive to the electromagnetic field control signal, and wherein heating or cooling of the magnetically or electrically active component causes the polymer to undergo a change in configuration that modifies the influence of the first material on the chemical reaction.

4. The reaction system of claim 1, wherein the remotely activatable control element is responsive to input of energy from the electromagnetic field control signal to modify one or more of the rate or kinetics of the chemical reaction through at least one of a mechanical, thermal or chemical mechanism.

5. The reaction system of claim 1, including a remote control signal source configured to generate an electromagnetic control signal sufficient to activate the remotely activatable control element to produce a desired rate or kinetics of the chemical reaction.
