Abstract:  Animal tagging is a useful technique for studying wildlife and wild ecologies. The value of of these studies can be expanded by increasing the lifetime of the tag, which is usually limited by battery life. Therefore, technologies which reduce the overall power consumption of a tag have the potential to expand the scope and quality of ecological monitoring. One technique for reducing the power consumption of a tag is to augment the power source with on-board energy harvesters, which scavenge ambient energy from the animal or the environment. Another technique is to adaptively reduce the fraction of time that high-power sensors are active. The ESCAPE project attempts to design, implement, and test a variety of these techniques in collars for large terrestrial mammals. Our collars implement kinetic, thermal, and solar harvesters to reduce battery load. We also present three algorithms for using low-power accelerometery measurements t! o reduce the duty cycle of costly GPS measurements. This project includes an electronic design to integrate these techniques in compact, low-power circuit.
