| Summary: | Microfluidics has become a very active area of research in both academia and
business over the last few decades as a rapidly rising interdisciplinary discipline
combining soft matter physics, biochemistry, and microsystems engineering.
Microfluidics enables the examination and use of smaller volumes of samples,
chemicals, and reagents. Digital microfluidics, a type of microfluidics, takes
advantage of the electrowetting-on-dielectric (EWOD) phenomenon to manipulate
liquid droplets. To regulate the electrodes, we devised a high-voltage switching
mechanism. The high-voltage switching system in this work is made up of 56 NMOS
common-source switching circuits that are controlled by an Arduino NANO with
seven 8-bit shift registers. Functional tests have been done up to 320 V operating
voltage which gives an output of 240 V on the electrodes. The electrode voltage
output frequency is 5 Hz. |
