Now fish can charge their own tracking tags

PNNL's self-powered acoustic fish-tracking tag is designed to track long-living fish such as sturgeon

Self-powering technology is showing up in a lot of places from clothing to tires, but fish seem to have been left out – until now. Scientists at the US Department of Energy's Pacific Northwest National Laboratory (PNNL) in Richland, Washington have developed a piezoelectric self-charging tracking tag that generates electricity from the fish's own movements, allowing researchers to keep tabs on them more accurately for longer periods of time.
