Abstract: A scanning antenna is provided in the present disclosure. The scanning antenna includes a first substrate and a second substrate which are arranged oppositely; a liquid crystal layer between the first substrate and the second substrate; and a feed signal access terminal and a plurality of phase shift units, where the plurality of phase shift units is connected with each other, each phase shift unit is connected to the feed signal access terminal, and electrical lengths between at least two phase shift units and the feed signal access terminal are different. The present disclosure not only realizes one-dimensional wave beam scanning, but also has desirable scanning effect. The bias voltage is not needed to be independently applied to each phase shift unit, which can greatly simplify the bias voltage line configuration and be beneficial for reducing production cost and wiring difficulty.

Abstract: Provided is a microfluidic chip. The microfluidic chip includes a first substrate and a second substrate disposed opposite to each other and drive electrodes, first sensing electrodes and second sensing electrodes disposed on a side of the first substrate. A microfluidic channel is formed between the first substrate and the second substrate and configured to accommodate at least one droplet. Different drive voltage signals are applied to adjacent drive electrodes, so as to drive the at least one droplet to move. Detection signals are applied to the first sensing electrodes and the second sensing electrodes, and a position of the at least one droplet is determined according to a change in capacitance between one first sensing electrode and an electrode corresponding thereto and a change in capacitance between one second sensing electrode and an electrode corresponding thereto when the at least one droplet flows by.
