Hywel Morgan and colleagues at Sharp Laboratories of Europe, the University of Southampton and Sharp Corporation, Japan, demonstrate a large area digital microfluidic array in this HOT article.
Using a thin film transistor (TFT) array rather than the traditional patterned electrodes usually used in electrowetting on dielectric (EWOD) devices, the team developed active matrix electrowetting on dielectric (AM-EWOD) devices. The TFT array enables each of the many thousand electrodes to be individually addressable, and the array is ‘fully reconfigurable and can be programmed to support multiple simultaneous operations’.
