DESCRIPTION:Even though the introduction of periodic structures was mostly
  motivated by structural strength and weight requirements\, recent studies
  have shown how the periodicity and/or nonlinearity can be exploited to at
 tenuate\, isolate and localize vibrations. Thus\, design of periodic struc
 tures permits to develop smart systems dedicated to vibration and acoustic
  passive and active control\, sensing applications\, improvement of the vi
 broacoustic performances and the enhancement of energy transport. In this 
 talk\, I will try to show how my research activities contributed in the de
 velopment and validation of methodologies and tools for the design of smar
 t structures based on the functionalization of nonlinearity and/or periodi
 city or quasi-periodicity. Several concepts have been proposed and exploit
 ed in order to enhance the performances of resonant MEMS and NEMS sensors\
 , Vibration Energy Harvesters (VEHs) and Capacitive Micromachined Ultrason
 ic Transducers (CMUTs).
