Our research activity has been hitherto focused in energy processing integrated circuits, encompassing both CMOS technologies for future generation multicore processors and RF transmitters, as well as new devices for exploring the ultimate energy density limits. These activities have been driven by ultra-low-power battery operated devices now migrating into energy harvesting enabled wireless sensor networks, pushing down scalability limits through the concurrence of new devices (more than Moore, GaN, graphene), circuit and system perspectives with the aim of a transversal impact to various applications, namely, among others, both downscaled portable terminals and distributed sensors for wireless monitoring, and practically all applications within the integrated system 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, smart grids
