Abstract

Many previous researches related with the cell-counter have measured transit of cells by the electrical-impedance method. Most of devices using electrical-impedance method have electrodes which are made by metal deposition process. In this study, the micro channel takes the place of metallic electrodes. The electric current is passed through the micro channel which is filled with PBS solution. The proposed device helps to save the time of fabrications of micro fluidic device. The process for metal deposition and fine alignment process between micro fluidic channel and base of electrodes can be canceled in proposed device. The signal for counting of a red blood cell of human and polymer microspheres were successfully measured.
