PNNL’s self-powered fish-tracking tag uses a flexible strip containing piezoelectric materials to emit tiny beeps that are recorded by underwater receivers. The device is designed for long-living fish such as sturgeon, eels and lamprey.
Department of Energy’s Pacific Northwest National Laboratory developed a self-charging tracking tag for fish behavioral studies. This new tag uses a flexible strip containing piezoelectric materials, which generate electricity through physical movement. The tags emit tiny beeps that are recorded by underwater receivers and are designed to track many different species of fish including long-living fish such as sturgeon and migratory species of concern such as eel and lamprey. It is described in the journalScientific Reports.
