Abstract: The invention concerns a system for measuring and displaying physiological parameters. It comprises, on the one hand, a sensor or sensors and a measuring device attached to the body, and on the other hand, a separate display device, for example a digital watch attached to the wrist, receiving from the measuring device the parameters to be displayed in the form of digitalised radio signals. A first application example concerns the measurement of the ECG signal and the display of parameters relating to the heart. A second example concerns the measurement of blood sugar levels and the display of insulin doses to be injected, if required.
