Eficiència energètica en computació, comunicació i infraestructures (xarxes de sensors, processadors multi-nucli, constel·lacions de satèl·lits petits, xarxes de distribució energètica), mitjançant arquitectures, circuits i dispositius de gestió d'energia, des de circuits integrats de gestió d'energia, captació d'energia i transferència sense fil d'energia, passant per models i control de sistemes de conversió eficient de potència, fins a sistemes d'energia renovables i microxarxes.

Our research activity has hitherto been focused on energy processing and integrated circuits, encompassing CMOS technologies for future-generation multicore processors and RF transmitters, as well as new devices for exploring ultimate energy density limits. These activities have been driven by ultra-low-power battery-operated devices that are now migrating into energy-harvesting-enabled wireless sensor networks and pushing down scalability limits through the concurrence of new devices (More than Moore, gallium nitride or GaN and graphene), circuit and system perspectives with the aim of a transversal impact to various applications, namely, downscaled portable terminals and distributed sensors for wireless monitoring and practically all applications within the integrated systems and circuits area. New challenges include wireless networks-on-chip for next-generation many-core processors for high-performance computing, nano-satellite swarms, wireless energy transfer and smart grids.
