    Abstract: The present disclosure describes electrowetting surfaces, digital microfluidic devices that include electrowetting surfaces, and methods of making electrowetting surfaces. In one example, an electrowetting surface can include a substrate, a plurality of electrodes on the substrate, and a nanoceramic coating over the plurality of electrodes. The electrodes can include a layer of conductive material deposited over the substrate. The nanoceramic coating can include ceramic nanoparticles bound together by a polymeric binder.

    Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes an interface, a first sensor, a second sensor, and control logic. The interface is to connect to a single contact pad of a host print apparatus. The first sensor is of a first type and is coupled to the interface. The second sensor is of a second type and is coupled to the interface. The second type is different from the first type. The control logic enables the first sensor or the second sensor to provide an enabled sensor. A voltage bias or a current bias applied to the interface generates a sensed current or a sensed voltage, respectively, on the interface indicating the state of the enabled sensor.

    Abstract: A logic circuitry package includes an interface to communicate with a print apparatus logic circuit and at least one logic circuit including at least one heater and a temperature sensor. The at least one logic circuit is configured to receive, via the interface, a heater command to address the at least one heater. The at least one logic circuit is configured to receive, via the interface, subsequent to the heater command, a sensor command corresponding to a sensor ID to address the temperature sensor. The at least one logic circuit is configured to transmit, via the interface, a digital value in response to the sensor command. The digital value corresponds to a print material level of a print material within a reservoir.
