Research area
My research activities at Holst Centre focus on the development of flexible electronics technology to enable flexible electronic products which are generally thin, lightweight, energy efficient and robust. Since 2014 I am full professor at the University of Technology of Eindhoven. My research chair ‘Flexible and large-area electronics’ is hosted by the research group Molecular Materials and nanosystems, which is headed by prof. R.A.J. Janssen.
In collaboration with leading companies and academic groups around the world I was part of the research team that demonstrated world-first prototypes such as foldable mobile phone displays and curved medical X-ray detectors. Technology transfer projects have enabled our partnering companies to absorb these new technologies and further scale up to applications, successfully completing the innovation cycle. For the coming years, I will concentrate on medical and health monitoring devices. Technologies originally developed to make foldable displays and semi-transparent imagers will be used in microfluidic lab/organ-on-a-chips, bioelectronics and brain-computer interfaces.
My current academic research focuses on charge and energy transport in disordered, mostly organic semiconductors and on the physics of light-sensing devices based on those. In addition, I work on novel organic ferro- and piezoelectric materials for amongst others medical ultrasound applications with the final goal to take ultrasound imaging out of the hospital and into the hands of everyone, enabling unobtrusive remote monitoring and diagnosis.
Recent results
Some highlights of 2020:
- A new method to fabricate a high-speed and compact thin-film transistor was published, and used to realize a ultra-high resolution display panel of 1000 pixels-per-inch.
- We made solution-processed organic photodetectors with enhanced light sensitivity in the near infrared region of the optical spectrum (650-1100nm). When integrated in large area arrays these were used to image vein patterns and monitor health parameters, such as heart beat (variability), oxygen saturation and pulse wave velocity. This work was awarded with a Distinguished Paper Award at SID conference in 2020.
- Solution processed lead halide perovskite semiconductors were used as direct conversion material to improve the spatial resolution as well sensitivity of medical X-ray detectors.
- We published a white-paper on the use of flexible electronics in Organ-on-chip developments.
