(last updated on 2022/12/30)Abstract:
Dependability is an important system attribute for mi-crofluidic lab-on-chip devices. On-line testing offers a promising method for detecting defects, fluidic abnormalities, and bioassay malfunctions during chip operation. However, previous techniques for reading test outcomes and analyzing pulse sequences are cumbersome, sensitive to the calibration of capacitive sensors, and error-prone. We present a built-in self-test (BIST) method for on-line testing of digital microfluidic lab-on-chip. This method utilizes microfluidic compactors based on droplet-based AND gates, which are implemented using digital microfluidics. Dynamic reconfiguration of these compactors ensures low area overhead and it allows BIST to be interleaved with bioassays in functional mode. ©2008 IEEE.
