SUMMARY

This work will target two applications relative to piezoelectric transduction.

The first project is based on a Surface Acoustic Wave device measuring strains in two directions along a plane. Such a device has been manufactured using microfabrication methods and tested on a loaded beam to determine its accuracy, while comparing the experimental output with the expected theoretical results.

The second project involves data transmission across a metallic barrier through piezoelectric transduction. A theoretical model has been derived and compared with numerical and experimental results. Improvements involving the bonding layers have been suggested and a design method to improve the output voltage has been provided.
