Raul Zamorano Illanes (DC9)
Design and development of optical sensors for WSN
Current work:
Raul’s work focuses on the development of Sensor Nodes for Internet of Things wireless sensor networks based on hybrid radio frequency and optical wireless communications. The use of Photovoltaic cells as dual-purpose devices for energy harvesting and communications, as well as optical cameras provided with CMOS image sensors, enables their use as optical receivers of communication signals due to the rolling shutter effect generated by the digitisation circuit. The development aims for the reduction of the power consumption and the establishment of secure and reliable optical wireless communications.

Background
Raul began his studies in Electrical Engineering at the University of Santiago de Chile, where he became involved, since his undergraduate studies, in the Multidisciplinary Centre for Research in Telecommunications Technologies (CIMTT), where he started to study optical wireless communications (OWC), specifically related to industrial applications for mining, precision agriculture and public health applications. He joined the Optical Communications Research Group, based at Northumbria University, for the development of sensor nodes focused on energy harvesting and OWC.
