TECHNOLOGICAL ACTIVITY OFFERED
- Realization of sensors based on surface acoustic waves (SAW). - Realization of surface acoustic wave devices (e.g., resonators, delay lines) - Realization of microfluidic devices - Characterization of micromechanical devices using Laser Doppler Vibrometry (LDV) - Wettability measurements (contact angle) - RF characterization of electronic devices, up to 4GHz.

DESCRIPTION OF RELATED RESEARCH
Surface acoustic wave (SAW) technology enables the manipulation and analysis of liquids at the micrometer scale, using, in this way, minimal volumes of material and raising detection capabilities. The objective of the research activity is to process a biological sample and analyze its molecular content on small (mm2-cm2) chips.
