Abstract
Among others things, techniques, systems, and apparatus are disclosed for recording electrophysiological signals. In one aspect, a microelectrode sensing device includes a printed circuit board (PCB), a chip unit electrically connected to the PCB, and a cell culture chamber positioned over the chip unit and sealed to the PCB with the chip unit between the PCB and the cell culture chamber. The chip unit includes a substrate; a conductive layer positioned over the substrate that includes one or more recording electrodes; an insulation layer positioned over the conductive layer; another conductive layer positioned over the insulation layer that includes positioning electrodes; and another insulation layer positioned over the other conductive layer. The recording and positioning electrodes are electrically independent so as to independently receive a stimulus signal at each recording electrode and positioning electrode and independently detect a sensed signal at each recording electrode.
