CMUT ultrasound startup Sonus raises funds
Sonus Microsystems Inc. (Vancouver, Canada) has raised $2.1 million to develop an ultrasound diagnostic imaging based on polymer MEMS actuators/sensors.
The company has raised more than $3.0 million since its founding in 2019. LDV Capital led the most recent financing with participation from angel investors and early-stage funds.
Sonus transducers are based on polymer-based Capacitive Micromachined Ultrasound Transducers (polyCMUTs). The company plans to use thousands of vibrating transducers on different types of substrate for imaging and materials testing applications.
The company has similarities to Exo Imaging Inc. (Santa Clara, California) which uses Piezoelectric Micromachined Ultrasonic Transducer (pMUT)-based chip technology. Sonus claims the use of polyCMUT is a “leap forward in the ultrasound field, offering enhanced imaging capabilities and a new standard for diagnostic and material testing.”
Sonus aims to address several use cases: disposable and miniature transducers, wearable transducers and large matrix array transducers.
“By utilizing polymers, we can manufacture polyCMUTs with fewer fabrication steps and minimal equipment, leading to substantial cost savings, swift iteration cycles, and unique capabilities,” said Carlos D. Gerardo, co-founder and director of R&D, in a statement.
