About us


Microflown was founded in 1998 by Hans Elias de Bree and Alex Koers, following the invention of the particle velocity sensor in 1994 by De Bree. The microflown sensor is a truly unique acoustic sensor. It is the first sensor in the world that allows to directly measure particle velocity as a physical quantity. Many years after the invention, with customers all over the world, Microflown AVISA has proven to be an important contributor to the world of battlefield acoustics.


Microflown was founded as an innovative start-up project at the University of Twente. It was there that De Bree finished his PhD and gathered an team of researchers and engineers. By 2003, after years of R&D, an industrialized particle velocity sensor was introduced to the automotive market. The company grew rapidly in the global automotive market. In 2008, Microflown AVISA was established and introduced the microflown-based AMMS (Acoustic Multi Mission Sensor), to the defense market. Since then the world’s first dedicated acoustic particle velocity sensor.


The microflown sensor technology along with its capabilities, come as a product of extensive research and development carried out by a committed team of engineers. Our engineers are constantly seeking for new opportunities to further improve our disruptive technology.


All microflown sensing elements are manufactured under the clean room technology. Remainder of the assembly process is carried out by a team of experienced employees that adhere to strict guidelines, ensuring the highest quality products.
