Abstract
A suspended particle sensing technique called travelling wave dielectrophoresis impedance measurement (TWDIM) is presented which uses travelling wave dielectrophoresis to concentrate suspended particles in solution to a subset of electrodes through which impedance sensing is used to sense particle concentrations. A microfabricated TWDIM device and associated electronic systems are presented, as well as methods of operation and experimental results determining yeast cell concentrations.
