Enhanced electromechanical performance of Ag/HfO2/Ag multilayer thin film by surface patterning for lead free piezoelectric energy harvesting
The development of lead-free piezoelectric energy harvesters for low-frequency vibration environments requires simultaneous selection of material, substrate, and structural characteristics. In this work, Ag/HfO2/Ag multilayer thin-film piezoelectric energy harvesters were fabricated on brass, aluminium, and copper subs...
