After the careful growth of special vertical well aligned ZnO nanowires, mechanical properties are being investigated using different techniques, among which nano-indentation has been used the most frequently.

This is then followed by the design of the electro-mechanical device based on these nano-wires. Indeed this is another challenging task. Our aim is develop a nano-generator which provides an efficiency of at least 30%.
