The mechanical properties of ZnO microwires have been studied using three different methods: quasi-static flexural measurements using atomic force microscopy, static measurements using a nano indenter, and dynamic flexural measurements using optical interferometry. ZnO microwires were synthesized by chemical vapor deposition method, and the crystal structure and quality were examined using x-ray diffraction and photoluminescence spectroscopy. The Young's moduli were estimated using聽the measurement results from the three methods, and they showed consistent values in the range 67.5-79.4聽GPa for microwires with diameters of 1.8聽渭m聽卤聽100聽nm.
