The project is developing new micro-electro-mechanical acoustic systems (MEMS), specifically microphones and ultrasonic transducers, with the aim of significantly improving medical instruments as well as the digitalisation of industrial processes. To this end, new types of piezoelectric materials such as aluminium scandium nitride, membrane structures and integration concepts are being researched. Specific licence-free hardware components and attack-proof artificial intelligence algorithms are integrated with customised assembly and connection technology solutions. This enables the development of highly miniaturised, high-performance microsystems with real-time signal processing. The systems will be used to monitor the heart and improve hearing, but also to measure gas flows and distances as well as for material testing and plant monitoring.

Over 20 million square metres of sandwich panels are produced in Germany every year, 200 million of them in the EU. They are used to seal off roofs and walls in building construction, for example on the façades of industrial halls and cold stores.

A consortium of seven partners is developing a new non-destructive and non-contact ultrasonic measurement technology to identify possible weak points and changes in material properties in the building materials during the production process. inoson is developing a non-contact ultrasonic sensor system suitable for integration into the production line to detect cavities and delamination. Air-coupled Lamb waves are used for this purpose.

As part of the project, an airborne ultrasonic system for non-contact and inline testing and surface weight determination of wooden panels is being developed. Inoson is developing a new ultrasonic transducer for harsh environments and the measurement electronics.
