Printed miniature loudspeaker listening into the future

Press Release / January 07, 2021

It has six corners and is about the size of a 1-cent piece: In an additive manufacturing process, miniature loudspeakers can be produced efficiently and cost-effectively as part of piezoelectric microelectromechanical systems - so-called piezo-MEMS - using a combination of inkjet printing and laser technology. This has been demonstrated by scientists at the Fraunhofer Institute for Laser Technology ILT, the Institute for Materials in Electrical Engineering 2 (IWE2) at RWTH Aachen University and the Fraunhofer Institute for Silicon Technology ISIT. The partners manufactured a corresponding demo component as part of the recently completed BMBF joint project “Generative Manufacturing of Efficient Piezo-MEMS for Microactuators (GENERATOR) ”.
