A team of engineers led by Sun Il Park of Texas A&M University designed an implant to help those who want to lose weight without resorting to radical methods. It is based on the well-known method of blocking the vagus nerve in the stomach area, through which the brain receives a satiety signal. By acting on this nerve, you can make the body believe that hunger is satisfied, even if a very small amount of food has entered the stomach.
Previously, during such an operation, a satiety stimulator was surgically installed opposite the nerve, where it worked on a permanent basis, using an integrated or wired power source. The new product uses a spiral radio receiver and a transformer that converts them into energy for LEDs. They are tiny, with minimal energy consumption, but they have enough light to effectively target the nerve.
Such an implant is not only smaller than analogs (about 1 cm in diameter), but also has a flexible mode of operation. In fact, it functions in response to a radio signal from the outside, so the user can decide for himself when to turn on the device in order to eat less, if circumstances so require. Or, the activator can be given to the attending physician or the doctor on duty at the sanatorium in order to monitor how the patients who are advised to lose weight eat.
