A combined travelling wave dielectrophoresis and impedance sensing device for sensing biological cell suspensions
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.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.
