1. An electrochemical device, comprising:
- two electrodes, wherein at least one of the electrodes includes an electrochemically active fluid layer;
an electrolyte not a part of the two electrodes configured to conduct 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, wherein the electrolyte is in contact with a surface of the electrochemically active fluid layer;
fluid directing structures configured to control at least one of a flow rate or a flow direction of the electrochemically active fluid layer by altering a fluid property of the electrochemically active fluid layer; and
a plurality of local sensors configured to detect an operating condition of the electrochemical device, each local sensor being configured to detect the operating condition at a predetermined location within the device;
wherein at least one local sensor of the plurality of local sensors is located at a single interface between one of the electrodes and the electrolyte and in direct contact with one of the electrodes and the electrolyte; and
wherein the at least one local sensor of the plurality of local sensors is configured to detect the operating condition of the electrochemical device at the single interface between one of the electrodes and the electrolyte.

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.
