Abstract: The device limits the leakage current in an electronic system for recording electrophysiological signals, where the transducer element is an active device, the device comprising an active transducer (1), intended to contact a human tissue, connected to a transimpedance amplifier (2), and a first resistor (6) connected parallel to the transimpedance amplifier (2), an alternate voltage source (7) and a direct voltage source (8), both connected to the active transducer (1), a first capacitor (3) connected between the alternate voltage source (7) and the active transducer (1), a second resistor (4) connected between the direct voltage source (8) and the active transducer (1), parallel with the first capacitor (3) and the alternate voltage source (7), and a second capacitor (5), connected between the active transducer (1) and the transimpedance amplifier (2).
