Maciej Haras, PhD Eng.

Research Assistant Professor


Graduate from Faculty of Electrical and Control Engineering, Gdańsk University of Technology, Poland and École Nationale Supérieure d'Ingénieurs Électriciens, Institut National Polytechnique de Grenoble, France (double M. Eng. in 2008). In 2016 he obtained Ph.D. from the Université Lille-1, France for investigating Silicon-based thermoelectric generators in Silicon On Insulator (SOI) technology, results of this work were awarded a prize in the best Ph.D. competition in 2015/2016 promotion.

In 2011 he joined STMicroelectronics, Crolles, France R&D department exploring innovative energy harvesting methods. In 2014 he integrated L’Institut d’Électronique, de Microélectronique et de Nanotechnologie (IEMN) Villeneuve-d'Ascq, France working on CMOS compatible thermoelectric generators and investigating mechanical properties of Silicon nanowires.

In 2017 he joined CEZAMAT. Currently he is developing innovative operational methods of energy harvesters leading to their performance boost. Additionally, he is working on new harvesting techniques from ubiquitous and distributed energy sources aimed at reaching self-supplying nodes for Internet of Things (IoT) applications.
