An innovative and promising alternative for future electronics is the integration of semiconducting metal oxide nanonets in devices. Nanonets are two dimensional network of interconnected nanowires randomly oriented in the plane. The advantages of using random horizontally oriented nanowires include an easy, low-cost integration process, high fault tolerance, good reproducibility, and a large surface area. However, there is limited knowledge available regarding the piezoelectric behaviour of these nanonets. Therefore, research was carried out to assess the effects of incorporating piezoelectric nanowires into nanonets to study the functional characteristics of both material and devices. As part of this effort, we were able to successfully integrate nanonet-based devices onto a flexible substrate. Thereafter, mechanical strain was applied to device in the form of both static and dynamic strains, to study their electro - mechanical behaviour evolution under varied orientation and magnitude of strain. Output voltage monitoring was conducted using open circuit tests to determine the voltage generated at different dynamic strain magnitude. Dynamic strain with the help of traction setup under in situ-SEM was used for understanding the modification in nanonet structure with exposure to strain at time zero. Combining these SEM observations with electrical measurements under static and dynamic strains for various device geometries will give us better understanding of piezoelectric behaviour of the ZnO-nanonet. Finally, this in-depth studies conducted will pave a way for successful implementation in energy conversion devices, especially Nanogenerators.
