1. An electrochemical device, comprising:
- two electrodes;
an electrolyte that conducts an ionic current from a first electrolyte surface in contact with one of the electrodes to a second electrolyte surface in contact with another of the electrodes,a first sensor located at an interface between one of the electrodes and the electrolyte, which first sensor detects an operating condition of the electrochemical device;
whereinat least one of the electrodes is a fluid-surfaced electrode including an electrochemically active fluid layer disposed over a solid support, a surface of the electrochemically active fluid layer being in direct physical contact with the electrolyte; and
the solid support includes an electrical control region separating two electrically distinct regions of the at least one fluid-surfaced electrode.

Abstract
An electrochemical device (such as a battery) includes at least one electrode having a fluid surface and one or more sensors configured to detect an operating condition of the device. Fluid-directing structures may modulate flow or retain fluid in response to the sensors. An electrolyte within the device may also include an ion-transport fluid, for example infiltrated into a porous solid support.
