Abstract: An electronic device provides a universal interface between sensors and an acquisition and processing system of the signals originating from the sensors, wherein the various sensors are connected to standardized terminals (1 . . . 6), appearing all identical to the user and comprising energization (M) and amplifying (A, A.sub.p) elements, capable of being adapted to said sensors, and identification means (R.sub.ECG, R.sub.PRE) for automatically recognizing the sensor present in the terminal, so as to allow programming the signal amplification, energization and processing elements.
