Bio

Henrique Leonel Gomes is Associate Professor in the Department of Electronics and Informatics, at the University of the Algarve, Faro, Portugal. He heads the organic electronics research group and he is the director of the doctoral plan of studies in electronics and telecommunication.
He was awarded BSc in Physics from the Universidade de Aveiro, Portugal and a PhD in Electronic Engineering in 1994 from the University of Wales, Bangor.
His research interests have been directed towards the electrical characterisation of electronic devices such as field effect transistors, diodes and capacitor structures. He has a recognized experience in small signal impedance measurement techniques. In the field of organic electronics, key contributions include (i) studies of gate bias stress in organic transistors, (ii) systematic investigation of polymer Schottky diodes and understanding their ac small signal response through equivalent circuit modelling, (iii) studies of resistive switching on polymer-based memory devices (plastic-RRAMs). Since 2000, his research activities have expanded to encompass the interaction between electronic devices and living cells to develop biosensors and biomedical devices.
Henrique Gomes established at the University of the Algarve a renowned infrastructure that provides a broad range of electrical measuring techniques to evaluate device performance, electrical stability, electrical noise and device reliability. His research laboratory has established a number of active collaborations with academia and with European companies, namely with Philips Research labs at Eindhoven, (NL) where together with Prof. Dago de Leeuw he published numerous papers on the characterization of organic field effect transistors (OFETs), organic light emitting diode (OLEDs), and resistive switching memory devices.
His most relevant and highly cited work was the study of the operational stability of organic thin film transistors.
Henrique Gomes has been involved in several European projects of the FP7 and H2020 programes in the areas of printed and flexible organic electronics and bioelectronics.
Currently his research group is comprised of 3 PhD students. Their research topics are related with the development and characterization of implantable devices to record and stimulate bioelectrical signals from living cells and tissues.
