A fault detection and diagnosis technique for digital microfluidic biochips

With the miniaturized biochips finding applications in safety-critical applications dependability of these chips has become an important issue since the consequences of a malfunction of such as chip could be catastrophic. Thus, these chips have to be tested both after the manufacture as well as during field operations. In this paper we propose an integrated testing and diagnosis strategy for the digital microfluidic biochips that can locate single as well as a certain class of multiple defects. This can be used to increase chip yield and dependability of the biochips in the field operation.
