PhD Ljubomir Vračar was born in Belgrade, 1973. He graduated from the Faculty of Electronic Engineering in Niš, in 1999. His graduation paper was titled “Analysing methods for disfunctioning microelectronics components”. His postgraduate studies were continued in Niš in the field of microelectronics. He worked as a research assistant at the Faculty of Electronic Engineering from 1999 till 2002, and then continued working as a teaching assistant. His MA thesis was titled “Automatic electric characterizing of thin dielectric gate MOS components”, which he presented at the Faculty in 2009. His PhD thesis was presented also in Niš in 2014 titled “Designing and realization of tactile energy harvesting micro systems”.
