People feel self-conscious about their food choices and may fudge (pun intended) the data. However, a new sensor that fits on a person’s tooth could cut out this unpredictable variable—human nature— altogether. Researchers from Tufts University School of Engineering designed a tiny sensor that, when stuck to a tooth, can wirelessly relay precise information about glucose, alcohol and salt intake. When the device comes in contact with salt, for example, its electrical properties shift, causing its other components to absorb and transmit different radiofr...
