In a first mode optimized for EWOD actuation, the control electronics is configured to control a supply of time varying voltages to the array element electrodes and the reference electrode, thereby generating an actuation voltage as a potential difference between voltages at the array element electrodes and the reference electrode. The reference electrode includes a first electrical connection and a second electrical connection. In a second mode, the control electronics further is configured to supply an electrical current flow between the first electrical connection and the second electrical connection to generate resistance heat for controlling temperature of the EWOD device. Control may include sensing a temperature of the EWOD device, and switching between operating in the first or second mode based on the sensed temperature."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multifunction electrode with combined heating and EWOD drive functionality","description":"An EWOD (or AM-EWOD) device includes a reference electrode and a plurality of array elements, each array element including an array element electrode, and control electronics.
