As part of the Fraunhofer Center for Sensor Intelligence ZSI, the intelligent and flexible ultrasonic sensor system “SonoOne” was developed according to the modular principle. “SonoOne” can serve the rapidly developing ultrasound market, especially in the field of portable systems, with innovative and highly flexible products. On the hardware side, “SonoOne” consists of cost-effective, matchbox-sized modules that can be easily combined and configured into a complete system for a wide variety of applications and, thanks to the modular concept, can be used universally for a wide range of acoustic measurement tasks.
