Abstract
The device 10 includes a liquid filled bellows activated battery composed of two non miscible fluids 14, 15 flowing through a channel 13 containing two electrodes 16, 17 of different metals. One of the fluids 14 is an electrolyte while the second 15 one is electrically non conducting. At rest the two electrodes 16, 17 are in the non conductive fluid 15. When the electrical device is actuated, manually or by an external force, the fluids surrounding the electrodes 16, 17 are replaced by the electrolyte 14 thus generating an electrical voltage between the two electrodes. The electrical current can be used to temporarily generate light or supply energy to another device. When the actuation mechanism is released, the electrodes 16, 17 are surrounded by the non conductive fluids 15 again and the electrical current is stopped.
