Health is a valuable commodity - an important field of application for the photonic microsystems of the Fraunhofer IPMS are therefore technologies for improved prevention, diagnostics and therapy in the medical field. Because life expectancy is increasing worldwide and with it the number of chronic diseases. Health awareness is also growing and the need for innovative prevention and diagnostics is increasing. MEMS technologies can be used in preventive medicine, for example to detect ingredients in food or to diagnose diseases at an early stage thanks to the latest visual imaging techniques. In addition, micromechanical components enable novel forms of therapy and the targeted dosage of medicines.
