Abstract:This paper reports a protable microfluid device with Bluetooth controller, which is conventi and lowcost. The theory of droplet actuation is electrowettingondielectric actuation. The device is made up of controller subsystem, highvoltage driver subsystem,bluetooth subsystem, software. The performance of our system is proved by testing the velocitory of droplet. The speed can reach 50 mm/s, when the droplet volume is 3 μL. This paper can help microfluidic chip used easily and widly.
