Application: An ewod device with sensing apparatus (Patent ID: US20240103047A1)

The patent filed by Sharp Corp. describes an electro-wetting on dielectric (EWOD) device that includes first and second substrates defining a fluid chamber, with various electrodes on each substrate. The device also incorporates a current sensor to detect differences in current flow between different electrodes via fluid packages in the chamber. The claims detail the specific configurations of the electrodes, the presence of a guard electrode, and methods for sensing electrical properties of fluid packages within the device.

The device's design allows for precise control and monitoring of fluid movement within the chamber, enabling applications such as monitoring reactions in fluid droplets. The method outlined in the patent involves applying bias voltages to specific electrodes, sensing currents between different electrodes and fluid packages, and comparing electrical properties to monitor reactions. The patent also includes details on the structure of the fluid packages, the use of hydrophobic coatings, and the arrangement of electrodes to facilitate efficient operation and accurate sensing of electrical properties.
