In this work, a highly sensitive vernier sensor based on Chirp Grating Fabry-Perot Interferometers (CG-FPI) is experimentally demonstrated for the detection of small strain signal in Lithium Polymer (LiPo) battery. The vernier sensor is assembled from two CG-FPIs with small difference in free-spectral range, vernier effect is achieved from the overlap of both reflection spectra that has a magnified strain sensitivity is similar to 33.22 pm/mu epsilon. Each CG-FPI comprises of two identical chirped gratings inscribed in a single mode fiber to produce a well-defined 8.5 nm-wide interference spectrum. This enables additional Fiber Bragg Grating (FBG) sensors to be incorporated into the same fiber sensor network without crosstalk and for better wavelength division multiplexing (WDM) efficiency. The fabrication is entirely based on grating inscription process without any physical modification on the fiber structure. In comparison with the standard FBGs, the proposed sensor offers 88.4% lower normalized root mean s
