Portable, electrically powered electronic devices (52) to be worn on a user's wrist, for example clocks, calculators, and paging receivers, are powered by a flat, solid-state polymer battery (32, 34) disposed within the watchband (22, 24) that secures the device to the user's wrist. A separate polymer battery may be provided in each of the two sections of such a watchband. The conductive current collector layer of the polymer battery may be used as a antenna for a wrist-borne receiver. Preferably, a loop antenna extending about the user's wrist is formed by interconnecting the conductive collector layers of polymer batteries in each of the two sections of the watchband through a conductive clasp or buckle assembly. |
