Recently, EWOD (Electrowetting on dielectric) has attracted a great deal of interest with applications of digital lab-on-a-chip in which microfluids are manipulated in a discrete form of droplets using electrical inputs. In most EWOD applications, the commonly used powering method is wired transmission, which may not be suitable for implantable lab-on-a-chip applications. In this paper, we will investigate wireless power transmission for EWOD utilizing the inductive coupling. Unlike the conventional inductive coupling, wireless EWOD requires a high voltage (> 50 V) at the receiver side which is connected to the EWOD chip since EWOD naturally operates under high input voltages. To satisfy this condition, the resonant inductive coupling method at a high resonant frequency is introduced and investigated. To optimize the transmission efficiency, we study the effects of many parameters such as the frequency, the inductance and the capacitance at the transmitter as well as receiver, the gap between the transmitter coil and receiver coil, and so on, by measuring the voltage at the receiver and the contact angle of droplets placed on wirelessly operated EWOD chip. In addition, by introducing amplitude modulation (AM) to the resonant inductive coupling, wireless AC electrowetting which generates droplet oscillations and is one of the commonly used operational modes is also achieved.

Electrowetting-on-dielectric (EWOD) is a microfluidic technology used for manipulating liquid droplets at microliter to nanoliter scale. EWOD has the ability to facilitate the accurate manipulation of liquid droplets, i.e., transporting, dispensing, splitting, and mixing. In this work, EWOD fabrication with suitable and affordable materials is proposed for creating EWOD lab-on-a-chip platforms. The EWOD platforms are applied for the diagnosis of early mortality syndrome (EMS) in shrimp by utilizing the colorimetric loop-mediated isothermal amplification method with pH-sensitive xylenol orange (LAMP–XO) diagnosis technique. The qualitative sensitivity is observed by comparing the limit of detection (LOD) while performing the LAMP–XO diagnosis test on the proposed lab-on-a-chip EWOD platform, alongside standard LAMP laboratory tests. The comparison results confirm the reliability of EMS diagnosis on the EWOD platform with qualitative sensitivity for detecting the EMS DNA plasmid concentration at 102 copies in a similar manner to the common LAMP diagnosis tests.
