Abstract

A microfluidic substrate and a manufacture method thereof, and a microfluidic panel are provided. The microfluidic substrate includes a base substrate, an acoustic wave generation device, and a first switching circuit. The acoustic wave generation device is on the base substrate and configured to emit an acoustic wave to drive a liquid droplet to move over the microfluidic substrates, the acoustic wave generation devices includes an acoustic wave driving electrode and an acoustic wave generation layer, the first switching circuit is on the base substrate, and the first switching circuit is electrically connected to the acoustic wave driving electrode and is configured to transmit an acoustic wave driving signal to the acoustic wave driving electrode, and the acoustic wave driving electrode is configured to drive the acoustic wave generation layer to generate the acoustic wave under control of the acoustic wave driving signal.
