Microfluidic Dance to Vivaldi

713 views 1 year ago
The seven microvalves at the bottom regulate the flow of dyes and open and close in synchrony with music. Software directs each microvalve to respond to a particular band of frequencies just like an equalizer creates light effects at a discotheque. The microvalves are constructed in transparent rubber and are about the width of a human hair. Since it is so small, a microvalve can respond to music very fast. The fluid layer in this device is less than one tenth of a millimeter deep. At these small scales, turbulence never occurs and fluids don't mix well, so instead of mixing the seven "laminar" streams perform a beautiful dance. Show less
