Semiconductor nanowires like zinc oxide nanowires are potential materials for future nanoscale sensors and actuators. Due to their unique length scale, they are expected to have length-scale dependent mechanical properties. In this paper, we report experimental investigations on the mechanical properties of zinc oxide nanowires. We have designed a MEMS test-bed for mechanical characterization of nanowires and use a microscale version of pick-and-place as a generic specimen preparation and manipulation technique. We performed experiments on zinc oxide nanowires inside a scanning electron microscope (SEM) and estimated the Young's modulus to be approximately 21 GPa and the fracture strain to vary from 5 % to 15 %.
