摘要： A microelectrode sensing device includes a substrate and an array of microelectrode sensors. Each sensor includes a first conductive layer that at least partially conducts electricity. The first conductive layer is formed above the substrate and patterned to include a recording electrode that measures electrical activities of target cells. Each sensor also includes a second conductive layer that at least partially conducts electricity. The second conductive layer is elevated above the first layer and patterned to include multiple positioning electrodes arranged to define a sensing region above the recording electrode. The positioning electrodes are designed to generate an electric field pattern in the sensing region to move and confine the target cells to a sub-region of the sensing region that at least partially overlaps the recording electrode.
