Short Biography

Alexander A. Altmann received his Master of Science degree in information system technology from Technische Universität in Darmstadt, Germany, in 2021. In his Master’s thesis “3D Printing and Analysis of Functional Materials” he investigated the 3D printing characteristics of functional materials used for ferroelectrets on the example of polypropylene (PP), polylactic acid (PLA) and thermoplastic polyurethane (TPU). He started his PhD by the Measurement and Sensor technology group at Technische Universität Darmstadt in January 2022.
