基于蓝牙控制的便携式数字微流控系统的研究

Research of portable digital microfluidic chip based on bluetooth

设计了一种基于蓝牙通信的便携式系统,相对于传统笨重的微流控设备,更加小巧、易用、价格低廉,通过蓝牙与手机集成,便于进一步的市场化普及。该系统基于电湿润法原理,给电极间施加电压,改变液滴与固体表面的润湿特性,从而使得液滴运动。该系统包括电极阵列、高压模块、控制模块、蓝牙通信模块以及配套APP。最后通过测量液滴的移动速度,对3μL的液滴,可以达到50mm/s的速度,满足了微流控系统的需要,证实了该设备的可行性。该研究可以促进微流控设备的低廉化、易用化。

This paper reports a protable microfluid device with Bluetooth controller,which is conventi and low-cost.The theory of droplet actuation is electrowetting-on-dielectric actuation.The device is made up of controller subsystem,high-voltage 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 3μL.This paper can help microfluidic chip used easily and widly.
