Focus on an industrial: Vermon

For almost four decades, Vermon has been designing and manufacturing custom ultrasonic probes and transducers for medical and industrial applications.

Building on its status as a pioneer in ultrasound imaging, and with a team of over 380 professionals in France and the USA, Vermon offers customized solutions to meet the complex needs of its customers, whether start-ups, major industrial groups or research laboratories.

Our engineering excellence and independence enable us to adapt quickly to specific requirements, offering solutions that are both high-performance and tailor-made.

Most of the ultrasonic probes developed by Vermon use a piezoelectric material called PZT, which contains a high proportion by mass of lead. For several years now, the RoHS directive has been forcing manufacturers to ban the use of lead in many fields. For the moment, ultrasonic medical applications benefit from regularly renewed exemptions. Nevertheless, it is essential to consider alternative solutions. That's why ARD MATEX's SPS-PIEZO project is a good example of how to replace piezoelectric materials with others that are more responsible for the environment and human health. The plan is to develop new ceramic formulations based on doped K0.5Na0.5NbO3 (KNN) and sintered using a new technique called SPS (Spark Plasma Sintering).

The samples produced during the project will then be integrated into prototype ultrasonic transducers and compared with versions made from leaded material. The aim is to produce dense, reliable and reproducible lead-free ceramics for a new generation of piezoelectric transducers.
