About

Jens Twiefel is a leading figure in the field of piezoelectric actuators and ultrasonic motors, with a particular focus on additive manufacturing and underwater propulsion. His research centers on the design, modeling, and validation of novel piezoelectric transducers, pushing the boundaries of how these smart materials can be miniaturized and applied in challenging environments. Twiefel’s most cited work, "A novel additive manufactured three-dimensional piezoelectric transducer" (2018, 66 citations), demonstrates his pioneering contribution to integrating 3D printing with piezoelectric technology, enabling complex geometries that were previously impossible to fabricate. This breakthrough has significant implications for creating more efficient and compact ultrasonic motors. Further expanding the application scope, his 2019 study on a "Novel Dual-Rotor Ultrasonic Motor for Underwater Propulsion" (19 citations) addresses a critical need in micro underwater vehicles (MUVs). By replacing bulky electromagnetic motors with a direct-drive ultrasonic alternative, Twiefel’s design eliminates the need for large mechanical transmission parts, offering a pathway to more agile, quieter, and highly maneuverable underwater explorers. His work is instrumental in advancing the practicality of MUVs for exploration and monitoring.
