There is need to develop a fast and efficient procedure for detecting blood type that makes use of an electronic measurement to minimize human error and is portable so that it can be used in triage situations. A process to develop a crossover frequency based blood typing device is described. Alternating field drives red blood cells over the sensing electrodes and depending on the capacitance measured between pairs of sensing electrodes, the position of these RBCs can be determined. The convergence/divergence of these cells at a particular frequency determines blood type, since each type has a characteristic frequency. This project …

Medical microdevices have gained popularity in the past few decades because they allow the medical laboratory to be taken out into the field and for disease diagnostics to happen with a smaller sample volume, at a lower cost and much faster. Blood is the human body's most readily available and informative diagnostic fluid because of the wealth of information it provides about the body's general health including enzymatic, proteomic and immunological states. The purpose of this project is to optimize operating conditions and study ABO-Rh erythrocytes dielectrophoretic responses to alternating current electric signals. The end goal of this project is …
