The project aimed to:

• Develop next-generation MEMS acoustic transducers (microphones & ultrasound sensors) with higher performance
• Enable miniaturized, low-power, and cost-efficient sensor systems for medical and industrial use
• Integrate AI algorithms and dedicated hardware for real-time, intelligent signal processing
• Bring new sensor technologies to high-volume production and strengthen European industry leadership
• Demonstrate applications in health & wellbeing (e.g., diagnostics, wearables) and digital industry & energy
• Support the transition toward a more digitalized “Society 5.0” through advanced sensing solutions
• Scale micro-electro-mechanical sensors to high-volume, cost-competitive production and enable their use across industrial and medical applications

During the project a high-performance broadband PMUT leveraging multiple vibrational mode shapes, together with its PDK (Process Design Kit), were developed to target advanced medical imaging applications. In parallel, air-coupled PMUTs and piezoelectric microphones (PMICs) were developed, supported by advanced characterization methodologies for applications in consumer electronics and digital industries.
