An active part of a sensor is formed, for example, by micro-machined silicon wafers bearing electronic elements, electrical conductors, connection pads, and pins. The pads are electrically connected to the pin ends by conductive elements. Then the wafer and the pin ends are plunged into an electrolytic bath to make an electrolytic deposit of conductive metal on the pin ends, the pads, and the conductive elements that connect them. Finally, this metal is oxidized or nitrized to form an insulating coat on the pin ends, the pads, and the conductive elements that connect them. Such a sensor may find particular application as a sensor designed to work in harsh environments.
