ENERGY HARVESTING TAG
Fish-mounted Micro-Turbine Power Tag
A fish-mounted sensing tag powered by water flow
We are researching a fish-mounted sensing tag that converts water flow generated during swimming into electrical power using a micro-turbine, with the goal of supporting longer-term sensing.
MICRO-TURBINE TAG
ENERGY HARVESTING
Turn swimming water flow into power for sensing.
CHALLENGE
The problem
Underwater sensing tags face a trade-off between battery capacity, attachment burden, and measurement duration. The challenge is to supplement available power without unnecessarily interfering with the animal’s movement.
APPROACH
Current approach
The concept uses a small turbine to capture water flow around the tag during swimming, then connects generation and storage to the sensing system. Fluid dynamics, mechanics, power circuitry, and measurement are designed together to validate attachment and available energy step by step.
RESEARCH THEMES
Current research themes
