Abstract
A microfluidic chip (100), an apparatus, a system, and a control and preparation method therefor. The method comprises: a substrate (101), and an electrode layer (102) and a functional layer (103) sequentially formed on the substrate (101), said electrode layer (102) comprising a plurality of electrode groups (1021) arranged in an array, the electrode groups (1021) being used for converting electrical signals into acoustic signals when an electrode group is activated, and transmitting the acoustic signals to the functional layer (103); and the functional layer (103) being used for carrying a sample to be tested, and for absorbing the acoustic wave signals emitted by the activated electrode group (1021) and converting same into thermal energy for heating the sample to be tested that is carried at the position corresponding to the activated electrode group (1021).
