Reconfiguration Techniques for Digital Microfluidic Biochips
نویسندگان
چکیده
As digital microfluidic biochips become widespread in safety-critical biochemical applications, system dependability emerges as a critical performance parameter. The dynamic reconfigurability inherent in digital microfluidic biochips can be utilized to bypass faulty cells, thereby supporting defect/fault tolerance. In this paper, we propose three different reconfiguration techniques and the corresponding defect/fault tolerance methodologies for digital microfluidic biochips. The proposed schemes ensure that the bioassays mapped to a droplet-based microfluidic array can still be executed on a defective biochip. Real-life biochemical assays, namely multiplexed diagnostics on human physiological fluids, are used to evaluate the proposed reconfiguration techniques.
