In 1986, Dr. Christian Buess developed an ultrasound flow sensor at the Institute for Electronics at the Swiss Federal Institute of Technology. Flow sensors of this type were also used in a Space Shuttle mission and in the Russian MIR Station.  In 1992, a collaboration with Professor Karl Harnoncourt was established with the goal of developing an ultrasound flow sensor for clinical routine applications. This collaboration led to the foundation of ndd Medizintechnik AG and to the development of the EasyOne spirometer.    In the year 2000, ndd Medical Technologies, Inc., in Andover, Massachusetts, was established. Today, the ndd team consists of experts with decades of experience in the development and distribution of spirometry products.
