Modeling and finite element analysis of mechanical behavior of flexible MEMS components

Abstract: This paper describes the studies of the mechanical characteristics of flexible MEMS components including theoretical approaches, finite element analysis and experimental investigations. Modeling and finite element analyses together with theoretical and experimental investigations are performed to estimate the elastic behavior of MEMS components as microcantilevers, microbridges and micromembranes. Finite element analysis of microcomponents deflections under different loading and the stress distribution in beam… Show more

“…The microstructures are used in different forms such as wire, cantilever beam, hinge, spring, spiral, gear, and other suspended structures; which either carry the load or have mechanical functions such as deflection, displacement, deformation, rotation and relative motion, etc. [3][4][5][6][7]. The different types of microwires are used in MEMS technology for sensing temperature, actuation of micro-actuators, sensors, and also in the medical field for orthodontic purposes [6,8].…”

“…Hinges are deformed in bending or torsion as a function of the applied force. Finite element analysis is a useful method to simulate the deflection of micromembrane, to compute their stiffness and to visualize the stress distribution in the micromembrane hinges [9].…”

“…A rigidez elástica é o parâmetro que descreve a relação entre deformação (deslocamento) e força para cada material. A rigidez de um material varia com o inverso do comprimento e a frequência de ressonância do componente é proporcional à raiz quadrada da rigidez elástica [PUSTAN et al, 2011], implicando que altas frequências podem ser atingidas ao miniaturizar estruturas. As propriedades mecânicas destes componentes têm influência significativa na confiabilidade e desempenho dos dispositivos [SOBOYEJO et al, 2003].…”

“…As micropontes são definidas por possuírem condições de fronteira do tipo fixo-fixo (figura 38) [PUSTAN et al, 2007;PUSTAN et al, 2011], indicando que ambas as extremidades da viga não são livres para se mover em qualquer direção, diferente das micro-vigas-em-balanço, que são caracterizadas por condições de fronteira do tipo fixo-livre. O modelo matemático desenvolvido neste tópico foi adaptado da literatura neste trabalho, e as equações obtidas pelo autor estão indicadas com um asterisco (*).…”
