About Me

I received my M.Sc. degree in Electrical Engineering with honours from the University of Twente following a study on magnetic recording carried out at the Philips Research Laboratories, Eindhoven. In 1992 I obtained the doctorate degree with honours from the same university and was rewarded the 1993 Veder price of the Dutch Electronics and Radio Engineering Society (NERG) for my PhD-thesis on nonlinear integrated optics devices. From 1992-1995 I was a fellow of the Royal Netherlands Academy of Arts and Sciences and studied second- and third-order non linear integrated optics devices. In this period I was a visiting scientist at the Center for Research and Education in Optics and Lasers in Orlando, Florida, USA. In 1995-1997 I worked on integrated optic devices for optical telecommunication at the University of Twente and the Delft University of Technology. Since1998 I have been associate professor in the Transducers Science and Technology (TST) group of the MESA+ research institute and mainly responsible for the micro-actuator research. The last few years my attention has shifted to biomimetic MEMS. In 2005 I was rewarded a NWO Vici grant for my project proposal BioEARS on cricket inspired flowsensors. Since May 1st 2007 I am a full-professor of the chair of MEMS-Design focussing on bioinspired transducers. My current research interests are Transducers science (including parametric and nonlinear transduction), Biomimetic sensors and 3D printed transducers. Since September 2020 I am the Chair of the Electrical Engineering discipline (department) of the EEMCS faculty at the UT.

My current research interests include Transducers science in general, biomimetic, parametric and nonlinear transduction in particular, MEMS, additive manufacturing, self-assembly. The main focus is on embedded sensing in which sensors are integrated by means of multi-material printing into (soft) structural parts without assembly. Research questions include (meta-)material properties of 3D printed structures, in particular those that can be used for sensing, including conductive, piezoresistive, piezoelectric, magnetic materials.
