1. A reaction device comprising:
- a body structure adapted for positioning in a body of an organism;
a reaction region located within the body structure on an inner surface of the reaction device or on the exterior of the body structure and operably coupled thereto, the reaction region including a first material located at and operably coupled to the reaction region and capable of influencing a chemical reaction at the reaction region; and
a remotely activatable control element physically coupled to the reaction region and responsive to an electromagnetic field control signal by changing in at least one dimension to produce a corresponding change in dimension of the reaction region, to thereby produce a modification to one or more of the rate or kinetics of the chemical reaction at the reaction region, wherein a surface area of the reaction region is increased by stretching of at least a portion of the reaction area responsive to the change in at least one dimension of the remotely activatable control element.

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.
