Droplet generation using microwave heating

A team from The University of Waterloo investigated a new method for droplet generation in microfluidic devices. Droplets were generated using a microwave coil that supplied heat at the interface of the two liquids. Although this method doesn’t have a promising throughput, the droplets generated can be easily controlled and have rapid response times.
