We have seen a wide variety of innovations in developing sensors for monitoring health. These include a tattoo that can track biometric data and an ingestible sensor that connects to your phone. But it can be difficult to accurately track what is going on inside our bodies. That may be about to change, with the introduction of miniaturised sensors developed by researchers at the Tufts University School of Engineering. The sensors are designed to be mounted on a tooth and communicate wirelessly with a mobile device. They are capable of transmitting information on the intake of substances such as glucose, salt and alcohol. This could one day enable the detection of a wide range of nutrients and physiological states.
