New sensor measures when your body starts burning fat


Today’s Video of the Day comes from ETH Zurich and features a look at a new sensor that can measure when your body starts to burn fat during exercise.

When the body begins the process of fat burning, an organic compound called acetone is released. The new sensor measures acetone concentration in expelled breath in real time, which indicates how much fat is burned. The sensor is coated with nanoparticles that interact with the acetone, so when the participant blows into the instrument, the results populate immediately.
