Abstract

A microfluidic chip and a driving method thereof. The microfluidic chip includes: a substrate, a drive unit array, a first decoding circuit and a second decoding circuit, and the drive unit array, the first decoding circuit and the second decoding circuit are all integrated in the On the base substrate; the first decoding circuit is configured to generate and output a target scanning driving signal to the driving unit array; the second decoding circuit is configured to generate and output a target driving voltage signal to the driving unit array The driving unit array includes a plurality of driving units configured to control the operation of droplets on the driving unit array based on the target scanning driving signal and the target driving voltage signal.

Description

technical field [0001] Embodiments of the present disclosure relate to a microfluidic chip and a driving method thereof. Background technique [0002] Microfluidics is an emerging technology, which has great application prospects in biology, chemistry, medicine and other fields. The microfluidic chip is the main platform for the realization of microfluidic technology. The basic operation units such as sample preparation, reaction, separation, and detection in biological, chemical, and medical analysis processes can be integrated into a micrometer-scale microfluidic chip. The entire analysis process can be automatically completed on the fluidic chip. There are hundreds or thousands of electrodes in a microfluidic chip, and it becomes difficult to control a certain electrode individually. SUMMARY OF THE INVENTION [0003] At least one embodiment of the present disclosure provides a microfluidic chip, including: a substrate substrate, a driving unit array, a first decoding ...
