Scientists will use two methods of harvesting ambient energy to power marine sensors on elephant seals. Current research is limited by the sensors' short battery lifespans or because data is stored on a memory chip and needs to be retrieved from the animal. Some systems offload data to satellites but the process requires a lot of energy. The new work will explore energy harvesting from the environment, using elephant seals for the initial experiments.
