We are the creators of the polymer-based ultrasound transducer technology (polyCMUTs)

Our Technology

Sonus Microsystems Inc. is the creator of a special type of ultrasound transducer fabricated with polymer materials (polyCMUTs). PolyCMUTs are considered a platform technology with applications in different markets, including Healthcare, Non-Destructive Testing (NDT), and consumer electronics. Some of the advantages of our technology are improved image quality, lower manufacturing costs, low-energy consumption, mechanical flexibility, optical transparency, among others.


Polymer-based Capacitive Micromachined Ultrasound Transducers (PolyCMUTs) are tiny vibrating drums (the diameter of a human hair) that can send and receive ultrasound waves to create images.


We have a unique laboratory in Canada with access to state-of-the-art microfabrication and measurement equipment, including class-100 cleanroom, a laser Doppler vibrometer, and acoustic measurement water tanks.


We are always exploring new applications of our polyCMUTs and building prototypes. We have all the tools and personnel to do it.


Sonus Microsystems was born in 2019 in Vancouver, BC, Canada, and is gradually building reputation as the provider of polymer-based ultrasound transducers that can outperform piezo-based and silicon-based technologies. Sonus Microsystems envisions to become a technology-enabler in multiple markets, including healthcare, non-destructive-testing (NDT) and consumer electronics.

We are constantly exploring what our potential customers want and need. Sign up to our mailing list to receive occasional updates and survey opportunities.
