​Dr. Nicolas Wyrsch was born in 1960 and studied physics at the ETH Zurich (Swiss Federal Institute of Technology). After obtaining his diploma in 1984,​​ he joined the group of Prof. Shah at the Institute of Microtechnology (IMT) of the​​​ University of Neuchâtel (Switzerland) ​to contribute to the development of a-Si:H solar cells, focusing on the study of the material's electronic properties​. After a stay at Princeton University in the United States, he obtained his Ph.D. from the University of Neuchatel in 1991. Since then, he has been team leader in the laboratory of photovoltaics (PV-LAB) of the Swiss Federal Institute of Technology in Lausanne​ (EPFL, Lausanne, Switzerland). His interests and main activities are focused on the development of silicon solar cells (more particularly​ on energy scavenging), functional layers, particle sensors and imagers, as well as on the integration of photovoltaic systems in the electric grid. He is author and co-author of more than 140 scientific publications.​

Dr. Lionel Buchaillot, PhD Mechanical Engineering is a Senior Researcher at CNRS, France, and the Director of the Institute of Electronics, Microelectronics and Nanotechnology (IEMN, Lille, France) since 2010. During the years 1991-1995, he has been interested in the contact mechanics of ultrasonic motors and the development of thin film shape memory alloys actuators for MEMS in the Laboratory for Integrated MicroMechatronic Systems at the University of Tokyo, Japan. In 1997, he worked as an R&D engineer for SFIM (now SAFRAN) and AVIAC Technologies Company. In 1998, he joined CNRS working in the field of silicon-based MEMS at IEMN. His research focuses on mechanical sensors and systems, RF MEMS / MEMS for microwaves and scientific micro- and nano-instruments. 
He is presently the editor of the IEEE Journal of Microelectromechanical Systems and of the IOP Journal of micromechanics and Microengineering. He is recipient of the CNRS Bronze medal.​​​​
