Cymatics is using sound to vibrate a fine material to create patterns.
How is it done?
Typically the surface of a plate, diaphragm or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste or liquid. Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency.
Use in Engineering
Inspired by periodic and symmetrical patterns at the air-liquid interface created by sound vibration, P. Chen and coworkers developed a method to engineer diverse structures from microscale materials using liquid-based templates. This liquid-based template can be dynamically reconfigured by tuning vibration frequency and acceleration.
