From April 2065438 to April 2003, Professor Chris Tumazzo and Professor Steve Bloom of Imperial College London, London, UK jointly designed an intelligent microchip, which can suppress appetite by acting on sympathetic nerves and provide an effective way to lose weight. The chip will be attached to the vagus nerve, which plays an important role in human appetite and other functions.

Chips and skin electrodes can detect electrical and chemical signals related to appetite in nerves. If the reading deviates from normal, the chip will send an electrical signal to the brain to reduce or prevent appetite. In addition, being able to identify chemical signals instead of electrical signals will make the chip more selective and accurate.

Professor Thoumazou, who is in charge of this research, said that the concept has been proved by preliminary experiments in the laboratory, and the chip is designed to be very small to ensure that appetite is restricted in a natural way without side effects. The smart slimming chip invented by Martin Fussenegger, a professor at the Federal Institute of Technology in Zurich, contains transgenic cells. The cells used contain two genes. One gene is responsible for detecting blood lipid levels. When it finds that the blood lipid level is abnormal, it will tell the other party that the gene inhibits appetite. These two genes together inhibit food intake. This chip can also monitor the contents of saturated and unsaturated animal or plant fats in blood at the same time.
