Abstract Analysis of microcantilever beam and ARROW microcantilever waveguides are presented in this work. The microcantilever is simulated by using the silicon nitride material. Electric voltage applied creates the deformation in the cantilever beam. The deformation leads to displacement of the beam. The displacement is due to bending of the cantilever tip. The integration of MEMS cantilever and ARROW waveguide results in the ARROW microcantilever waveguide. The ARROW microcantilever waveguide quality factor, electric filed intensity and sensitivity analysis are the three important parameters presented. The quality factor is obtained by varying the air gap distance between cantilever waveguide and output waveguide. Through this simulation using FDTD sensitivity up to 73.78 nm/RIU has been achieved for the microcantilever arrow waveguide.

Micro-Electro-Mechanical Systems (MEMS) noted as micro generation have grown to advance greater than in previous decades. This venture reports approximately the silicon-based piezoresistive (PZR) microcantilever for glucose sensing. Elevated sensitivity, highest operation collection, extensive frequency reaction, excessive resolution, proper linearity are the majority preferred residences of the sensor. The displacement strain at specific limits, sensitivity and deformation is analyzed by means of finite element method for two exclusive structures. 3D structural modeling of three layers in micromechanical sensors may be achieved at ANSYS 14.5. In bio-medical request, adsorption of glucose on a functionalized exterior of the micro-fabricated cantilever will gather an exterior strain and therefore meander the cantilever beam. The cantilever meandering enhances the sensitivity of the microcantilevers sensor. Instead of capacitive accelerometer which produces changes in the seismic mass, the best method is PZR accelerometer that takes advantage of change in resistance and produces electrical output signal. The argument of the resolution problem in the study of a system for PZR detection technique with requirement of devices like Low pressure chemical vapor deposition (LPCVD) etc. is easily done by introducing stress concentrated region (SCR) which is considered as slot in the structure so that it enhances sensitivity of the device further higher. This technique is used for a sample, to detect and monitor glucose level and it produces simulation wrapping up in the microcantilever beam such as twist, pressure, injure and displacement.
