Design of Electrical/Biological Circuits and Systems using Electrowetting on Dielectric (EWOD)
This work aims to use electrowetting on dielectric to automate biological experiments. The top left image seen below shows an experimental system fabricated and tested at UNLV with electrodes placed on the top board. These electrodes are used, with capacitive position sensing, to determine the location of droplets for moving, merging, and splitting.
Videos showing experimental results are found in: contact angle, contact line pinning cancellation, dispensing volume control, splitting small droplets, and vibration speed-up.
This effort is part of Yiyan Li's doctoral research. Click images to enlarge.
