Abstract
A microfluidic chip and controlling method are provided. The microfluidic chip includes a microfluidic substrate, comprising a first substrate, a droplet driving assembly over the first substrate, and a temperature detection assembly. The droplet driving assembly includes a first electrode layer having a plurality of control electrodes, and each of the plurality of control electrodes is configured as part of a driving unit to drive a droplet to move along a predetermined path over the microfluidic substrate. The temperature detection assembly comprises at least one temperature sensor. The at least one temperature sensor positionally corresponds to the plurality of control electrodes such that each of the at least one temperature sensor detects a temperature at a position associated with one of the plurality of control electrodes corresponding to the each of the at least one temperature sensor.
