A sensor having a crystal having a first face and a second face, the first face comprising a prong, wherein the sensor is adapted to track movement of an object in a medium other than vacuum and the prong has a frequency of vibration that substantially matched a frequency of vibration of the crystal is disclosed. A method to track movement of an object a method of manufacturing a system to track movement of the object is also disclosed. The method of tracking includes creating a sensor adapted to track movement of the object in medium other than vacuum and providing a spatial tracking map. The method of manufacturing the system to track movement of the object includes fabricating a plurality if sensors, arranging the plurality of sensors in a three-dimensional space and feeding data from the plurality of sensors into a mapping algorithm.
