The small implantable device seen in the hands of the researcher below is made to fight hunger pangs and help people lose weight.
Obesity is an increasing problem around the world with over 700 million adults and children globally considered obese.
Obesity can lead to all manner of health problems, and scientists from the University of Wisconsin-Madison have created an implant that could help the obese lose weight.
The device is small and has no battery to operate.
The researchers say that in those rat tests, the animals were able to shed almost 40% of their body weight.
The implant is small at less than 1cm across; it’s about a third the size of a penny.
