Ultrasonic Clothes Dryers

Posted May 5, 2017

Scientists at the US Department of Energy’s Oak Ridge National Laboratory (ORNL) introduced an ultrasonic clothes drying technology. The new technology relies on high-frequency vibrations to shake the water from fabric by essentially atomizing the moisture. It dries fabric faster and using 5 times less energy than simply using heat and is estimated that the this approach can dry clothes twice as fast as conventional dryers, cutting drying times to about 20 minutes. The process also results in almost no lint being produced.

The ultrasonic vibrations are produced by piezoelectric transducers that rapidly contract and expand in response to an electric current. The researchers have now scaled them up and integrated multiple transducers into a full-scale press dryer and clothes dryer drum.

This technology will be available to consumers in the nearest future. You can check out how your next clothes dryer might work in the video below.
