Abstract

We have developed nanoscale guitar strings with extremely low energy dissipation, using silicon under stress. The exceptional lifetime of these mechanical oscillators makes them perfect tools to sense minuscule forces in their environment, and to explore how quantum mechanics can apply to macroscopic objects.
