Tribosonics uses patented technology
jointly developed at the University of Sheffield and the
University of Bristol for the measurement of thin layers
using ultrasonic reflection. This technology, known as
Ultrasensor, has been proven in an assortment of field
trials and laboratory experiments. The papers below detail
some of the proving work that has been done.
