Transducers Science and Technology group

Welcome! We at TST specialize in three-dimensional nano- and microfabrication based on top down lithography methods. Within the MESA+ Research Institute for Nanotechnology, we invent new fabrication techniques and acquire fundamental understanding on the underlying physics. We demonstrate the techniques on various devices and try to understand the science of working principles and design, with the aim to ultimately transfer our knowledge to industry.

We contribute substantially to the classical physics education of engineers at the University of Twente, mainly the Electrical Engineering and Advanced Technology bachelor tracks, Electrical Engineering and Nanotechnology master programs and Nanodevices and Systems graduate school.

Improving signal-to-noise ratio by additive noise in a MEMS based slider structure

IEEE’s Journal of Micromechanical Systems (JMEMS) has recently accepted our paper “Stochastic Resonance in a Voltage-Controlled Micromechanical Slider” and put it online. Stochastic resonance (SR) is a phenomenon that has been extensively investigated theoretically, but which is much harder to study experimentally. In this paper, we report on an experimental micromechanical slider structure that allows for full control of most of the parameters that are of importance for the occurrence of SR. ... read more

A biomimetic accelerometer inspired by the cricket's clavate hair

Today our paper “A biomimetic accelerometer inspired by the cricket's clavate hair” has been published in the prestigious journal for cross-disciplinary research of the Royal Society Interface (ranked fifth in JCR's multidisciplinary category). The paper is based on crickets so-called clavate hairs, which they use to sense (gravitational) acceleration and to obtain information on their orientation. ... read more

Magnetic sperm cells

In his master thesis project, Herman Dijkslag of the RAM group demonstrated how artificial sperm cells fabricated at TST can be propelled by external magnetic fields. ... read more

Harmen Droogendijk graduates cum laude

28th February 2014 Harmen defended his thesis “Bio-inspired MEMS Flow and Inertial Sensors”. The thesis comprises the work done over a period of four and half years (including 6 months dedicated to acquiring a first degree teaching license in mathematics and physics). The research is centered around biomimetic sensors (flow-, acceleration-, rotation- and rotation-rate-sensing) and the use of parametric effects to improve sensing characteristics or even enable sensing that would be impossible without the use of parametric effects. ... read more
