Technical Paper


Cholera is caused by vibriocholera bacteria which were present in water or food. Diarrhea is caused by E. coli bacteria which were present in water or food. Bio-sensors were used for the detection of waterborne elements in the fluids. This, paper provides a bio-sensor for the detection of cholera and diarrehea which is present in the water using capacitive technique. The bio-sensor is designed using FEM tool. Two types of channel based bio-sensor was designed cylindrical based and rectangular based. A simulation is also performed with and without the presence of bacteria cells in water and resultant capacitance is also computed using FEM tool. The sensitivity of the device is also calculated with and without the presence of bacteria cells in the water. The flow velocity, flow rate of cylindrical and rectangular channels is performed using FEM tool.
