It’s a microchip-monitor embedded in a person’s skin that can send continuous updates to a smartphone about crucial medical decisions such as chemotherapy or chronic-disease dosage.

It’s half the size of a paper clip and can monitor five proteins and organic acids simultaneously.

It sends the results to a smartphone or computer, allowing a doctor to tailor the dose of medications in real time and see how the patient is responding.

The team of 50 scientists in Switzerland has tested the device on animals and hopes it make it commercially available to doctors and their patients in four years.
