1. A system for measuring a physiological variable in a body, which system comprises:

  • a sensor (314) arranged to be disposed in the body for measuring the physiological variable and to provide a signal representing the measured physiological variable;

    a control unit (322) arranged to be disposed outside the body; and

    a wired connection (311) between the sensor and the control unit to provide a supply voltage from the control unit to the sensor, and to communicate said signal from the sensor to the control unit, wherein the control unit has a modulator (301) for modulating a carrier signal with the received signal representing the measured physiological variable and a communication interface (401, 701) for wireless communication of the modulated signal.
