How to Control Micro Mechanical Oscillators and Resonators

Micro scale and nano ale oscillators can be used to design new types of resonators. In the musical saw, even without a continuous source of energy, you can have this localized vibrationl mode persist for a long time. This is because the energy only moves into the ambient environment. And through this geometry, control the topological dynamics of this little membrane allowing its oscillations to persist much longer than you might have imagined in the absence of the geometry.
