A precision position-detecting system using a wireless LC resonant magnetic marker was developed. The marker consists of an inductor and a capacitor without battery or electric wires, driven wirelessly by electromagnetic induction. The positional accuracy is less than 1 mm within 150 mm of the pickup coil array. The optimal design made it possible to improve the positional accuracy of the system. The system can be used for highly accurate motion-capturing without magnetic shielding because it is free from the earth's field. In addition, it has the potential to capture multi-point motion because it allows the markers to have individual frequency bands.
