Abstract:
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; and a 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.
