Claim Text:
1. An active matrix electrowetting on dielectric (AM-EWOD) device, comprising: a plurality of array elements configured to manipulate one or more droplets of fluid on an array, each of the array elements including a corresponding array element circuit, wherein each array element circuit includes: wherein the sensor circuitry includes an active element, and a capacitance across the active element is different in the first mode of operation as compared to the second mode of operation; wherein an output of the write circuitry is connected to a terminal of the active element; and wherein the write circuitry is configured to receive an initialization voltage, and the capacitance of the active element is changed by modifying the initialization voltage, thereby selecting a mode of operation of the sensor circuitry as between the first mode of operation and the second mode of operation.
