The device is made up of several punched plates (12,14,50) and covers (13,15) with a frame (11) separating the upper and lower assembly. A flexible substrate (20) has the calculator Ico (22) and discrete components (23) mounted on it and fits within the frame (A). A second area (B) retains the display (30) and a third (c) retains the battery (60). The lithinm battery consists of extremely thin layers (40) to form the plates and electrolyte. The battery is heat sealed inside a plastic film (60) into which conductors (61) are set. Clsing the seal forces the conductors into intimate contact with the cell surface, allowing power to be transferred to the flexible substrate.
