Abstract: An electrowetting on dielectric (EWOD) device able to self-detect a movement of a droplet under test includes a detection chip, a power switch module, a detection module, and a determination module. The detection chip includes a channel, several driving electrodes, and a detection electrode. Each driving electrode can couple with the detection electrode to form a driving loop. The power switch module provides one of a first voltage and a second voltage, to rock the droplet along, and a third voltage can also be applied to a specified driving electrode. The detection module computes a capacitance recovery time of the detection voltage changing from a peak voltage to a reference voltage in one cycle of a voltage period. The determination module confirms a position of the droplet based on the recovery time. A method for a self-detecting a movement of the droplet in EWOD device is also disclosed.

Abstract: A heating structure includes a first cover plate, a second cover plate, a conductive portion; and two first driving electrodes. The conductive portion is connected to the first cover plate and the second cover plate. The first cover plate, the conductive portion, and the second cover plate cooperatively define a channel for carrying a microbead. The channel includes a flow path. The two first driving electrodes are electrically connected to the conductive portion to energize the conductive portion. When the conductive portion is energized, a driving force is generated to drive the microbead away from a sidewall of the conductive portion to the flow path. A nucleic acid detection kit with the detection chip, and a nucleic acid detection device with the nucleic acid detection kit are also disclosed.

Abstract: An electrowetting on dielectric (EWOD) device able to self-detect an open-circuit or closed-circuit condition includes a detection chip, a power input module, a switch module, a detection module, and a determination module. The detection chip includes a channel, several driving electrodes, and a detection electrode. Each driving electrode can couple with the detection electrode to form the driving loop. The switch unit selects one of the driving electrodes to be electrically connected to the power input module for receiving a power voltage from the power input module. The detection module receives a detection voltage outputted by the detection electrode and accumulates the detection voltage to obtain an accumulated voltage. The determination module compares the accumulated voltage with a specified voltage for determining whether the driving loop is open-circuit or closed-circuit. A method for a self-detection circuit in EWOD device is also disclosed.
