The present paper peruses MEMS based piezoresistive pressure sensor and its fabrication techniques. Simulation of the pressure sensor is done by using COMSOL Multiphysics software for P-type silicon piezoresistor. The deflection of N-type silicon diaphragm depends upon the Young’s modulus of the material and varies with the amount of force applied to the diaphragm. The simulation result emphasi...

Singlet oxygen ( 1 O2) is the major cytotoxic agent during photodynamic therapy (PDT). A previously developed model that incorporates the diffusion equation for the light transport in tissue and the macroscopic kinetic equations for the generation of the singlet oxygen, can be used to numerically calculate the distance-dependent reacted 1 O2 using finiteelement method (FEM). The formula of reac...

A fuel cell has been considered as an efficient and clean alternative power source for automobile industry since the energy crisis forced people to find a substitution for fossil fuels. A proton exchange membrane fuel cell, also known as polymer electrolyte membrane fuel cell (PEMFC), becomes a prime candidate for applications in vehicles because of its following features: the PEMFC operates at...

Magnetic induction tomography is an imaging technique used to image electromagnetic properties of object by using the eddy current effect. (MIT) a non-destructive method that greatly in agriculture industry. This provided opportunity improve quality agricultural products. MIT simulation was for agarwood existence detection. paper presented system contains 7 channel coils receiver and transmitte...
