Improving automobiles is a real problem for many scientists and engineers working to improve the consumer characteristics of machines and increase their reliability and safety.  We explore all new components that offer better performance and lower cost. One of the important components of a modern car is the sensor. Sensors must provide accurate and timely information about onboard computer systems and actuators. Sensors are used in almost all vehicle systems. Measures the temperature and pressure of air, fuel, oil and coolant in the engine. Many moving parts of a car (crankshafts, camshafts, throttles, shafts in gearboxes, wheels and exhaust gas recirculation valves) are connected to position and speed sensors. Many sensors are used in active safety systems

One of these sensors is a position sensor. Especially used as a crankshaft position (CKP) sensor in ignition systems. In modern automobiles, these sensors operate on the inductive or Hall effect [6,7] and are possible on huge magnetoresistance [8,9]. Sensors operating in the magnetoelectric effect (ME) have also been proposed [10,11]. A significant improvement in these sensors would be novel ME structures that do not require magnetization to operate. Based on this structure, it is possible to construct a sensor that does not include a permanent magnet or a magnetization solenoid.

Magnetoelectricity is a substance that has both magnetic and electrical sequences. The interconnection of magnetic, electrical and elastic properties of multimerises leads to the fact that cross-effects are possible by linking the magnetic and electrical properties of materials. ME sensors have several advantages over conventional sensors. In particular, they have higher sensitivity, smaller dimensions and lower mass, as well as ensure operation without additional energy sources.
