Testing of Digital Microfluidic Biochips with Arbitrary Layouts

Abstract

As in the case of VLSI circuits, digital microfluidic biochips must be adequately tested after manufacturing to guarantee the correctness of the biomedical experiments. In this work, we propose an efficient test method for digital microfluidic biochips. In contrast to related prior work, the proposed test method is not only able to cover all chip defects but also applicable to arbitrary chip layouts. Experiments demonstrate that using the proposed test method, the test-application time can be reduced significantly compared to related prior work.
