The nano guitar illustrates inaudible technology that is not meant for musical entertainment. The application of frequencies generated by nano-objects is called sonification. Such objects can represent numerical data and provide support for information processing activities of many different kinds that produce synthetic non-verbal sounds. Since the manufacture of the nano-guitar, researchers in the lab headed by Dr. Craighead have built even tinier devices. One thought is that they may be useful as tiny scales to measure tinier particles, such as bacteria, which may aid in diagnosis.
