Abstract
A method for making a plurality of low-cost microelectrode arrays (MEAs) on one substrate utilizing certain unmodified printed circuit board (PCB) fabrication processes and selected materials. In some embodiments, a MEA device is composed of a thin polymer substrate containing patterned conductive traces. Coverlays on both sides of the substrate insulate the conductive traces and defines the electrodes. Preferably, flexible PCB technology is utilized to simultaneously define the microelectrode arrays. In an embodiment, the sensor is an integrated temperature sensor/heater in which the MEA device operates to record extracellular electrical signals from electrically active cell cultures. The present invention enables economical and efficient mass production of MEA devices, making them particularly suitable for disposable applications such as drug discovery, biosensors, etc.
