Scientists are developing a groundbreaking kinetic tracker for wildlife, aiming to overcome the limitations of battery-powered and fragile solar-powered GPS devices. Biologist Rasmus Worsøe Havmøller and his team at the University of Copenhagen have created a kinetic tracker that harnesses an animal’s movements to generate electricity for location pings. While not yet suitable for frequent GPS fixes, this technology could revolutionize wildlife conservation efforts by providing a lightweight and cost-effective alternative for tracking elusive animals, including those that hunt and travel at night, such as tigers, leopards, and wolves.
