About

U. Ehrfeld is a pioneering figure in microsystems technology, best known for his foundational contributions to the LIGA process—a revolutionary technique that combines deep lithography with replication to fabricate high-aspect-ratio, three-dimensional microstructures. His key research areas span microengineering, materials science, and precision manufacturing, with a focus on enabling the use of diverse materials—including metals, polymers, glasses, and ceramics—in microdevices. Ehrfeld’s seminal 2002 work, "Materials for LIGA products," which has garnered over 20 citations, systematically demonstrated how application-specific materials could be tailored for LIGA-based components, significantly expanding the process’s utility across industries such as optics, biomedical devices, and microfluidics. His research laid the groundwork for mass-producing intricate microstructures with exceptional precision, bridging the gap between laboratory innovation and industrial application. Ehrfeld’s impact is further underscored by his role in advancing replication technologies, making LIGA a cornerstone of modern microfabrication. For students and researchers, his work exemplifies how material selection and process integration can unlock new frontiers in miniaturization, inspiring continued exploration in microengineering and beyond.
