It will soon be possible to measure ultrasonic sound using water, air, light and nanotechnology – over a hundred times more accurately than with existing sensors. This innovative method is based on a new principle for an ultrasound sensor developed by Helmut Rathgen of the University of Twente. The new sound sensor enables accurate ultrasound scans with a small mobile device and can be used to improve the sonar equipment used on boats. The sensor designed consists of a glass fibre.
