MICROFLUIDIC CHIP

The embodiments of the present application disclose a microfluidic chip. The microfluidic chip comprises a first substrate and a second substrate arranged opposite to each other. A microfluidic channel is formed between the first substrate and the second substrate, and the microfluidic channel is configured to accommodate at least one droplet. A plurality of driving electrodes and a plurality of sensing electrodes are located on one side of the first substrate, and the plurality of driving electrodes are arranged in an array. The sensing electrodes comprise at least one first branch electrode and at least one second branch electrode. The first branch electrode extends along a first direction, and the second branch electrode extends along a second direction. Adjacent driving electrodes are loaded with different driving voltage signals so as to drive the droplet to move. The plurality of sensing electrodes are loaded with detection signals. The position of the droplet is determined according to changes in the c
