About

H.H. Langen is a pioneering figure at the intersection of microengineering, robotics, and precision motion control. His research spans microrobotics, microfactories, and nanotechnologies, with a focus on developing novel systems for microhandling and microassembly. Langen’s most cited work, “Issues in precision motion control and microhandling” (2002, 34 citations), illustrates the convergence of MEMS, system control, and ultraprecision design, opening new application domains in microrobotics and nanotechnology. He introduced an innovative 5 DOF fully parallel robot (2010, 21 citations) that uniquely combines 3T1R motion with linear grasping, eliminating the need for separate end-effectors. His contributions to haptic tele-operated systems for microassembly (2010, 17 citations) further demonstrate his impact in enabling precise, remote manipulation at the microscale. Langen also advanced glass micro-machining through spark-assisted electrochemical etching (SACE), as seen in his work on 3D microstructuring with an AFM (2004, 4 citations) and force measurements during SACE (2000, 3 citations). His interdisciplinary approach has significantly influenced the design of parallel robots and precision systems, making him a key contributor to the evolution of microengineering and robotics.
