In this articles we will develop a new in-situ residual stress detection method based on flexible hinges for thin-film materials, then described the detection principle theoretically and simulated its properties by FEA method.
Introduction The methods of thin-film materials growth or deposition include physical vapor deposition (PVD), chemical vapor deposition (CVD) and thermal oxidation [1].

Insuring good mechanical stability of the developed materials, thus avoiding devices degradation, is in fact a crucial research issue which requires an estimation of the materials’ hardness and elastic modulus .The most appropriate technique to measure these properties is nano-indentation.
