Researcher Mechanical Engineering Nicole XU from the University of Colorado Boulder Rust Ear jellyfish (Aurelia Aurita) Out with tiny electronic devices that stimulate their swimming muscles, as if they have a kind of pacemaker. This way the animals can be sent in a certain direction. The animals can reach depths that are hardly accessible for people or expensive robots.
Temperature
Sensors are linked to the chips that collect temperature, acidity and other environmental data along the way. “There is something special about the way they move,” says Xu on the website of the university. “We want to use that, not only for climate research, but also to develop new, economical underwater vehicles.”

According to Xu, the animals are not bothered by it. They eat, move and plant themselves as if nothing is wrong. “It is our responsibility to take ethical questions seriously,” she tells an interviewer of the university. “But so far we see that the animals are healthy and thrive well.”
Depths and measuring equipment
The oceans warm up and become more acidic. That threatens many animal species, but it is precisely in the most difficult depths that it is not known what exactly happens. Traditional measuring equipment is often too expensive and too log to get there.

The ear jellyfish is ideal for this work. They have been around for more than 500 million years, have no brains or pain receptors and are the most energy -efficient swimmers in the animal kingdom. The ear jellyfish is transparent, with four round rings in the middle reminiscent of ears – hence the name. They can be found all over the world, from coastal waters to considerable depths, and they can be tiny or as big as a breakfast board.

Xu is not the only one who is working on this idea. For example, at the American University of Caltech, researchers are experimenting with jellyfish who can swim faster with the help of electronics and can be steered better. In Japan it is looked at how electrodes and smart software (machine learning) can help to check the movements of jellyfish even more accurately.
