Abstract
An electronic device includes a flexible conductive member having a first length, and a battery substrate having a second length shorter or equal than the first length. There is an active battery on the battery substrate. An adhesive layer couples the active battery and the battery substrate to the flexible conductive member such that the active battery and the flexible conductive member are electrically coupled, and such that the flexible substrate encapsulates the active battery and the upper portion of the battery substrate without an intervening layer. The flexible conductive member includes an insulating flexible base layer having a conductive via formed therein. Upper and lower metallized layers are formed on the insulating flexible base layer and are electrically coupled to one another by the conductive via.
