Since 1999 part of the team works designing microelectronic chips for a large variety of applications. As part of this research, the group is one of the pioneer groups designing CMOS single photons detectors (SPADs) with applications in radiation and point-of-care biomedical devices. Related to this activity, they have developed new small customized cameras and new types of ubiquitous chip-sized and lens-less microscopes.
In the frame of Nanostructured Materials, the group work since 2006 in printed electronics, developing their own inks to print conductors, semiconductors and isolants, mainly in the form of metal-oxides and polymers. The nanostructured films and devices obtained from this ecofriendly processes are nowadays focused on biocompatible optoelectronics and sensing applications. Another main research line of the group refers to harvesting and scavenging energy for low-power applications and self-powered devices.
