SUMMARY OR ABSTRACT
Text of Note
Nowadays, with the MEMS technologyexpanding, it is possible to design implantable devices in human body thatcould be used in Bio Engineering. Measurement of glucose level is one of the interesting fields of Bio Engineering. Continual measurement of it is of great importancefor diabeticpatients, since with increasing glucose level, the risk of syncope increasestoo. In this project, animplantable and integrated system is introduced. Its structure is constituted of a RF circuit, a Bio Fuel cell and a Glucose sensor. In this project it is worked specifically on Bio Fuel Cell and Glucose Sensor.Biofuel Cell Fuel cells are an important technology for wide variety of applications including micro power, auxiliary power, transportation power, central power and stationary power for buildings and other distributed generation applications. The proton exchange membrane fuel cell (PEMFC) known as fuel cell benefit from working at low temperature, compactness, and easy and safe operational modes. These preferences make this type of fuel celluseful in energy harvesting. Bio Fuel Cell, as a type of PEMFC, converts chemical energy to electrical energy. The product energy is generally used for driving pacemaker, insulin pump, drug delivery systems, making BFC feasible to implant miniature in human body to drive small devises.In this devise the chemical energy is supplied by oxidation of blood's glucose. The glucose oxidizes in anode and the catalyst in anode plays an impressive role in the output power and polarization curve. Additionally, partly complete model of an implantable BFC has been simulated and fabricated, which was experimented by Krezenmacher et al. in an In-vitro medium. For simulation of BFC, we have used COMSOL ۳.۵ Multiphysics softwarefor finite elements analysis. We compared the simulation data with the experimental ones. We explore the power of Bio Fuel Cell for different catalysts in definition thicknesses of membrane; however, we obtain maximum power out up equal ۲۴ ?W for Platen catalyst with ۲۸۰ ?m thickness of membrane. Glucose sensor In the first stage, in a laboratory situation, we meager the Maximum output power for different concentrations of glucose; thereafter, we simulate the glucose sensor. Finally, a comparison between the experimental andthe simulation data is represented
