Abstract:

With the development of science and technology,most prior work on the research of the digital microfluidic biochips assume that the electrode uses a large number of independent control pins to control,thus a significant increase of the manufacturing costs.In this paper,according to the droplet routing path,we use the broadcast addressing method to assume the number of the maximum electrodes that one pin can drive after experiments,then use that value to partition the electrode-actuation sequence,and finally reduce the number of control pins.We evaluate the proposed optimization method by comparing with other methods of early research.Results show that our method can effectively reduce the number of control pins and process the control signals.

Key words: digital microfluidic biochips;electrode drive;control signal process
