Research of Dielectric Breakdown Microfluidic Sampling Chip

الملخص EN

Microfluidic chip is mainly driven electrically by external electrode and array electrode, but there are certain disadvantages in both of ways, which affect the promotion and application of microfluidic technology.

This paper discusses a scheme that uses the conductive solution in a microchannel made by PDMS, replacing electrodes and the way of dielectric breakdown to achieve microfluidic chip driver.

It could reduce the driving voltage and simplify the chip production process.

To prove the feasibility of this method, we produced a microfluidic chip used in PDMS material with the lithography technology and experimented it.

The results showed that using the dielectric breakdown to achieve microfluidic chip driver is feasible, and it has certain application prospect.
