The smallest 'washing machine' ever made

By Jerry Odumbe Otieno | January 28th 2015 at 00:00:00 GMT +0300

A team from the Swiss engineering lab MPI Ultrasonics believes that their novel invention may eliminate the use of laundry machines in the future. The new creation, christened Dolfi, is a smooth, white pocket-sized pebble that mimics a washing bar soap. To use it, the user fills up a basin with water, adds a washing detergent, turns on the small device and drops it in water.

Dolfi then begins to vibrate vigorously producing a range of high-frequency sound waves which stir the water with the detergent, creating powerful water micro-jets as bubbles implode (in the same manner a washing machine would) and washing clothes in process.

The sound waves produced are generated by a transducer within the gadget that converts electrical energy into ultrasonic sound waves. The device receives its electrical power from an external power source through a physical cable.
