Printed Miniature Loudspeaker With A Future Perspective
It has six corners and is about the size of a 1-cent piece: In an additive manufacturing process, miniature loudspeakers as part of piezoelectric, microelectromechanical systems - so-called piezo-MEMS - can be efficiently and cost-effectively manufactured using a combination of inkjet printing and laser technology. This is proven by scientists from 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. A corresponding demo component was created as part of the recently completed BMBF joint project »Generative production of efficient piezo-MEMS for micro-actuators (GENERATOR).
