Geert's pages

Hello, I am Geert Langereis and I am the 13th generation of Sijbrant Dulles van de Langereijs, who was born in Niedorp, somewhere halfway the 16th century. I received a M.S. in Electrical Engineering (1994) and Ergonomics (1994) from the University of Twente, the Netherlands. In addition, I obtained a biomedical specialization and endorsement for the study of Electrical Engineering. In 1999, I received a Ph.D. from the same university in the field of self-learning multi-sensor systems for monitoring washing processes. That research was paid for by Unilever.


From 1999 until 2009 I worked at the industrial research laboratories of Philips and NXP. In the first years, I was a member of a group for optical storage, and was involved with standards for high speed CD-R and DVD+R recording. In the same group, I developed the algorithms for self-learning CD/DVD-recorders, currently on the market under the “SolidBurn” logo. Later on, I became a senior scientist in a group for healthcare devices where I worked on drug delivery systems and the monitoring of electrophysiological signals. In that period I was project leader of a large European project on human stress estimation systems integrated in wearable textiles. Already at the University of Twente, and later on at Philips Research, I used Micro-ElectroMechanical Systems (MEMS) technology to develop silicon microphones and other sensors. When NXP was split-off of Philips, I focused more on MEMS technology and applications for the automotive and mobile market. In that period, I was a member of the organizing committee of the IEEE Portable conference.

In 2009 I joined the department of Industrial Design of the TU/e as an assistant professor. In this occupation, I consolidated my expertise in smart algorithms for multi-sensor wearable systems, applied to care and healthcare applications. Teaching was done in the field of microcontrollers and interfacing with sensor electronics, mostly by coaching student projects. In that period, I was a member of the International Community of Teachers of Mathematical Modelling and Applications (ICTMA), and a guest editor for the Dutch Journal of Ergonomics. The background in both medical related electronics and ergonomics was a unique combination for an Industrial Design department. My research focused on sensor systems around the human body, and the algorithms needed to tailor the sensed information into useful merits. I am still fascinated by chronobiology and options to measure emotional states.

In 2013 and 2014, I was a group leader at Omron Europe in the Industrial Automation business unit. The R&D group developed the hardware and embedded software for Industrial PC's and Human-Machine Interfaces (HMI).

As of August 2014, I am a lecturer at the Fontys University of Applied Sciences in Eindhoven. I am the leader of the research line for Detection and Measurment. Some teaching materials and developed sensing principles can be found on the Wiki page for Healthcare related Sensors and in regular publications.

The proven expertise is in the field of smart multi sensor systems. This was applied in many fields like algorithms for process optimization, electrochemistry, electrophysiological systems, microcontrollers, silicon micromachining, human stress estimation and lumped element modeling. Besides these technical fields, I was many times consulted to explore the technical value of other companies in view of acquisitions and collaborations. This was done by patent landscaping, temporarily working at other companies and technical product assessments. In 2002 and 2003, I was involved with setting up a new research department for Philips in Shanghai. My concern was the technical program and training of new employees.

Besides this study and work related background, I am married and have two daughters. We live our happy life in the city of Eindhoven, The Netherlands. We have three ponies (Jenny and Mickey).

The time that is left, is spent on reading about penguin biology and playing guitar, at least as we are not on travel.
