Paper Abstract
There have been a number of new applications for energy harvesting with the ever-decreasing power consumption
of microelectronic devices. In this paper we explore a new area of marine animal energy harvesting for use in
powering tags known as bio-loggers. These devices record data about the animal or its surroundings, but have
always had limited deployment times due to battery depletion. Reduced solar irradiance below the water's surface
provides the impetus to explore other energy harvesting concepts beyond solar power for use on marine animals.
We review existing tag technologies in relation to this application, specifically relating to energy consumption.
Additionally, we propose a new idea for energy harvesting, using hydrostatic pressure changes as a source for
energy production. We present initial testing results of a bench-top model and show that the daily energy
harvesting potential from this technology can meet or exceed that consumed by current marine bio-logging tags.
The application of this concept in the arena of bio-logging technology could substantially increase bio-logger
deployment lifetimes, allowing for longitudinal studies over the course of multiple breeding and/or migration
cycles.
