Electromagnetic Buoy Paralyzes Jellyfish to Protect Beachgoers from Stings

Few holiday experiences are as frustrating as being stung by a jellyfish at the beach — but that ordeal may soon become a thing of the past.

Researchers from Spain's Universitat Politècnica de València (UPV) and the University of Alicante have joined forces to develop an innovative anti-jellyfish electromagnetic buoy that effectively prevents jellyfish from entering swimming zones, creating a safer environment for beachgoers.

How It Works

The buoy uses electromagnetic waves to paralyze jellyfish, rendering them unable to swim toward designated beach swimming areas. Compared with conventional physical barriers such as nets or chemical repellents, electromagnetic technology is considered more environmentally friendly and causes significantly less disruption to the marine ecosystem.

Research Background and Significance

In recent years, jellyfish populations along coastlines worldwide have grown markedly due to climate change and shifting ocean conditions, posing challenges for beach safety and the tourism industry. The joint research initiative by UPV and the University of Alicante directly addresses the seasonal jellyfish invasions common along the Mediterranean coast each summer, offering a concrete, technology-driven solution.

The technology is still under active development. The research team aims to deploy the buoy system at major beaches in the future, providing swimmers with a more secure and enjoyable marine leisure experience.
