Abstract
A device for reducing power consumption in medical electrical equipment, implantable in the human body, having a sensor, which includes a sensor element and sensor electronic circuitry for sensing a parameter relevant to control of the equipment's in vivo operation, also has a comparator which compares the sensor element's output signal to a predesignated threshold value and switches the sensor electronic circuitry from a passive mode with low power consumption to an active mode with heavier power consumption or vice-versa, depending on the magnitude of the sensor element's signal in relation to the threshold value.
