Ger de Graaf

Research interests

Microsystems for gas sensing, optical spectrometry and precision circuits for readout. Micromachining and microfabrication technology in general.


Ger de Graaf was born a long time ago in Delft. He has been a staff member at the Electronic Instrumentation Laboratory of the Faculty of Electrical Engineering at Delft University of Technology since 1976.

He received his BSEE degree in Electrical and Control Engineering with honours from the Technische Hogeschool in Rotterdam in 1983. His graduation project was on the damping of piezo-electric accelerometers by active feedback, supported by Bruel&Kjaer. From 1992 to 1996 he also owned  a part-time consultancy company specializing in computer controlled measurement systems, working on an automated system for the energy measurement of heating systems in apartment buildings.

He has worked on the design of circuits for optical sensors in bipolar and CMOS technology. After this he started working on MEMS, mainly on infrared sensors and capacitive accelerometers and mixed-mode CMOS signal processing circuits for these devices. Around 2003 he started his PhD project on infrared optical systems and in 2008 he received his Ph.D. Degree from Delft University with the dissertation "Mid-Infrared Microspectrometer Systems". He is a (co-)author of around 130 scientific publications and main author of around 30 international scientific papers since 1988. He is a member of the IEEE and holds one patent.

At present I work on IC compatible gas sensors for thermal conductivity, viscosity and optical sensors for infrared absorption gas sensing. He is a project leader in an STW project on sensors for natural and combustible gas and participates in the national EDGaR gas research project.


Currently I am a tutor and mentor for two groups in the first year lab course EPO and also involved in the MSc course "Microsystems Integration" and "Electronic Instrumentation".
