We are the creators of the polymer-based ultrasound transducer technology (polyCMUTs)
Our Technology
Sonus Microsystems Inc. is the creator of polyCMUTs, a special type of ultrasound transducer fabricated with polymer materials. Sonus Microsystems is the first company to offer fully customizable linear and matrix array transducers for consumer ultrasound applications. The unique size, flexibility, and customizability of Sonus Microsystems’ polyCMUT technology allows for applications not previously possible with traditional piezoelectric or silicon-based ultrasound transducers. PolyCMUTs are considered a platform technology with applications in different markets, including Healthcare, Non-Destructive Testing (NDT), and consumer electronics.
PolyCMUTs
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.
Lab
We have a unique laboratory in Canada with access to state-of-the-art microfabrication and measurement equipment, including class-100 cleanroom, optical and acoustic characterization tools.
Research
Our primary focus is biomedical ultrasound application. Our polyCMUT technology can also be applied to material inspection or even consumer electronic applications
ABOUT US
Sonus Microsystems was founded in 2019 by the inventors of the polyCMUT technology, Dr. Carlos D. Gerardo, Dr. Edmond Cretu, and Dr. Robert Rohling; who have over 60 years of combined academic and industry experience and 400+ peer-reviewed scientific papers between them. Sonus Microsystems envisions to become a technology-enabler in multiple markets
