1. An energy storage cell comprising:

  • a cell wall having an inner surface and an outer surface;

    a first electrode;

    a second electrode positioned relative to the first electrode in a manner generating electrochemical activity between the first electrode and the second electrode;

    an active region responsive to the electrochemical activity, the active region comprising a plurality of localized measurement regions exhibiting a cell property;

    a sensing platform coupled to the inner surface of the cell wall proximate the localized measurement regions, the sensing platform comprising a plurality of data transmitting structures each comprising a first inductive coil coupled to each of a plurality of sensing elements for collecting and transmitting data corresponding to the cell property in each of the localized measurement regions; and

    a data receiving structure coupled to the outer surface of the cell wall, the data receiving structure spaced apart and separated from the sensing platform by the cell wall, the data receiving structure comprising at least one second inductive coil receiving the transmitted signals from the plurality of data transmitting structures,wherein the plurality of sensing elements comprises a temperature sensing element and a strain sensing element for measuring, respectively, temperature and strain at the localized measurement regions.
