1. An integrated combined rechargeable battery and wirelesslyrecharging timepiece apparatus comprising:

  • a flexible support structure;

    a first conductive layer deposited on a first surface area of the support structure;

    a thin-film battery deposited as successive thin-film depositions over at least a portion of the first conductive layer, the battery comprising a cathode layer;

    a solid-state electrolyte layer, and an anode layer deposited such that either the anode layer or the cathode layer is in electrical contact with the first conductive layer, and the electrolyte layer in contact with and completely separating the anode layer and the cathode layer, wherein the electrolyte layer includes LiPON;

    a wireless energy-receiving device mounted to the support structure; and

    an electronic timepiece circuit mounted to the support structure and including a recharging circuit, the recharging circuit electrically coupled to the battery and the energy-receiving device to recharge the battery using energy received by the energy-receiving device;

    wherein the support structure, and the first conductive layer deposited on a first surface area of the support structure form a substrate and the successive thin-film depositions form the thin-film battery affixed to at least one surface of the substrate;

    wherein the apparatus further includes a protective coating located on the thin-film battery;

    wherein the electronic timepiece circuit forms a device that is affixed to said thin-film battery via the protective coating, and electrically coupled to the thin-film battery through a conductor external to the thin-film battery and to the device; and

    wherein the apparatus further includes an encapsulant to encapsulate the device and external conductor.
