We propose a new design of the nano-scale strain monitoring system, which consists of a fiber Bragg grating and a standard vibration source. The measurement resolution is increased from μ-strain to n-strain, using the perturbation method on the fiber grating stretching length. The change in Bragg wavelength due to the change in fiber stretching length is simulated. Results obtained have shown the feasibility of using such a proposed system to monitor small strain and vibration in the nano-scale range. The relationships between temperature and strain on the one hand, and Bragg wavelength on the other hand are plotted. This is shown as it has potential of being used in simultaneous measurement.
