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.

1. A system comprising: a body structure adapted for positioning in an environment;a reaction region operably coupled to the body structure including a first material configured to influence a chemical reaction involving at least one material from the environment; anda remotely activatable control element operably coupled to the body structure and responsive to a static or quasi-static magnetic field control signal or a static or quasi-static electric field control signal to modify one or more of the rate or kinetics of the chemical reaction on the reaction region, wherein the remotely activatable control element responds to the control signal by changing in at least one dimension, wherein additional portions of the reaction region are exposed responsive to the change in at least one dimension of the remotely activatable control element, and wherein exposure of additional portions of the reaction region exposes additional functional groups to produce at least a local change in osmolality, pH, surface energy, or surface charge. 2. The system of claim 1, wherein the reaction region is located in an interior portion of the body structure and is at least intermittently in fluid communication with the environment via at least one inlet or outlet. 3. The system of claim 2, further including a valve responsive to the change in at least one dimension of the remotely activatable control element to modify at least one of the flow of fluid into the reaction region or the flow of fluid out of the reaction region responsive to the change in at least one dimension of the remotely activatable control element. 4. The system of claim 1, wherein the reaction region is located on an exterior portion of the body structure in fluid communication with the environment. 5. The system of claim 1, wherein the remotely activatable control element includes a valve element or a structural element. 6. The system of claim 1, wherein the remotely activatable control element modifies one or more of the rate or kinetics of the chemical reaction by modifying the influence of the first material on the chemical reaction, or the rate of exposure of a reactant configured to participate in the chemical reaction to the first material. 7. The system of claim 1, wherein the remotely activatable control element includes at least one of a polymer, ceramic, dielectric, metal, shape memory material, bimetallic structure, hydrogel, ferrogel, ferroelectric, magnetically active material, or electrically active material. 8. The system of claim 1, wherein at least one of a surface area of the reaction region or a volume containing the reaction region within the interior portion of the body structure is increased responsive to the change in at least one dimension of the remotely activatable control element. 9. The system of claim 1, including at least one of an outlet through which a product of the chemical reaction is released into the environment or an inlet through which a second material configured to participate in the chemical reaction enters the reaction region. 10. The system of claim 1, wherein the first material is selected from a reactant that is modified by participation in the chemical reaction, a non-reactant material that modifies at least one condition at which the chemical reaction occurs, or a catalyst that facilitates the chemical reaction but is not significantly modified by the chemical reaction. 11. The system of claim 1, including a body structure adapted for positioning in the environment, wherein the environment is selected from a body of an organism, a body of water, a contained fluid volume, an industrial fluid volume, an agricultural fluid volume, a swimming pool, an aquarium, a drinking water supply, and a HVAC system cooling water supply.
