On Friday, 6 November 2020, Frieder Lucklum held his inaugural lecture as a Professor at DTU entitled ‘From MEMS, Ultrasonic Sensors, and 3D-Printing to Phononics and Mechanical-Acoustic Microsystems’. The lecture was virtual and was streamed via Zoom and YouTube, enabling it to be viewed/reviewed here.
At the beginning of the year, Frieder Lucklum was appointed as the new Head of the CAMM research centre. The centre conducts research into the link between acoustic and mechanical microsystems, which are essential to the production of hearing aids and headphones, among other things. Denmark is among the world leaders in this field. Three of the largest manufacturers of hearing aids are Danish. Together with DTU Electrical Engineering and DTU Mechanical Engineering, they have formed the CAMM research centre.
At the inaugural lecture, Frieder Lucklum shared his knowledge of some of his early and new research projects and presented various research results from MEMS (Micro-Electro-Mechanical Systems), ultrasonic sensors, and 3D printing as well as their application in phononic and mechanical-acoustic microsystems.
The combination of advanced manufacturing technologies, calculation models, and new concepts such as acoustic metamaterials open up entirely new possibilities hitherto impossible with conventional materials and systems. During the lecture, Frieder Lucklum presented his vision of building a sustainable foundation to promote technical expertise within microacoustics, numerical modeling, and optimization.
Microacoustic devices and systems such as hearing aids, miniature headsets, or ultrasonic sensors and actuators, are at the crossroads between multiple engineering disciplines and benefit our society in different ways today. Technological advancements in acoustic systems require expertise from electrical engineering, mechanical engineering, physics, and other fields.
Understanding the propagation and interaction of vibrations and waves in confined spaces, different solid and fluid materials, and over widely different frequencies utilizes rigorous analytical, numerical, and experimental methods. Advances in fabrication techniques such as micromachining and MEMS technology or additive manufacturing open new freedom in design and integration. Novel design concepts include the unique physical behaviour found in acoustic metamaterials and phononic crystals to control wave propagation in ways not possible with classical materials.
This inaugural lecture will illustrate research results from MEMS, ultrasonic sensors, and 3Dprinting and the application in phononic devices and mechanical-acoustic microsystems. The lecture will lay out a vision to build a sustainable foundation for joining and advancing the engineering expertise in microacoustics, numerical modelling and optimization, and materials and process technology.
