這款電磁浮標是如何阻止水母的？

The buoy emits electromagnetic waves that paralyze jellyfish, preventing them from swimming into designated beach swimming areas. Unlike physical nets or chemical repellents, this method is considered more environmentally friendly and causes less disruption to the marine ecosystem.

這項技術目前可以在海灘上使用了嗎？

Not yet. The technology is still in active development. The research team at UPV and the University of Alicante hopes to deploy the buoy system at major beaches in the future, but no commercial deployment has been announced.

為什麼現在需要這種防水母技術？

Jellyfish populations along global coastlines have grown significantly due to climate change and changing ocean conditions, increasing the risk of stings for beachgoers and impacting coastal tourism. The Mediterranean coast is particularly affected by seasonal jellyfish invasions each summer.

Electromagnetic Buoy Paralyzes Jellyfish to Protect Beachgoers from Stings

Researchers from Spain's Universitat Politècnica de València (UPV) and the University of Alicante have jointly developed an innovative electromagnetic buoy capable of paralyzing jellyfish and preventing them from entering designated swimming areas, offering beachgoers a safer ocean experience.

Highlights

Spain's UPV and the University of Alicante have jointly developed an electromagnetic buoy that paralyzes jellyfish to prevent them from entering beach swimming zones.

The buoy uses electromagnetic waves as its core mechanism — an approach considered more eco-friendly than conventional physical nets or chemical jellyfish repellents.

Rising jellyfish populations driven by climate change are increasingly threatening beach safety and coastal tourism, particularly along the Mediterranean coast.

The technology remains in the research and development phase, with no confirmed timeline for commercial beach deployment announced by either institution.

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.
