Group's history

Group's history

The ECAS group was initiated more than 15 years ago in the spirit to combine micro and nanoelectromechanical devices with standard CMOS technologies. the final purpouse was to achieve novel nano and micro-devices with unprecedent capabilities thanks to the monolithical integration with the signal processing  circuitry. During these years, the group has been contributing to the field of ultrasensitive mass sensors, RF applications with the development of new oscillators systems based on NEMS devices and signal processing systems as filters, mixers. The exploitation of non-linear properties of the NEMS devices has led to the development of memory devices as well as new high stable oscilators with frequencies in the range of 10's of MHz. Oscillators based on piezoelectric  material, AlN over CMOS, have been also investigated providing systems with oscillation frequency up to 330MHz. Nowadays, the group is developing ultrasound transducers using AlN piezoelectrical material for new imaging systems and biometric identification systems.

During these years several PhD thesis has been done, being former members of the group during the PhD studies:
