Abstract
An oxygen sensor device and method for a motor vehicle having an electrode within an outer shell for measuring oxygen in exhaust gas exiting the vehicle. A communication device, powered by a capacitor, wirelessly transmits the measured amount of oxygen from the electrode to a powertrain control module. Vibration transmitting from the motor vehicle shakes a magnet, wound inside a coil, for generating the electrical current used by the capacitor.
