Abstract A new method for rapid prototyping of microfluidic device on a piezoelectric substrate is presented. A clear plastic film is used to cut for channel patterns mold, which is pasted on a glass. Poly(dimethylsiloxane) (PDMS) is filled on the glass and solidified in an oven. After having been peeled off the plastic mold, the PMDS is bonded with a piezoelectric substrate with an interdigital transducer. Red ink solution is used to verify the function of microfluidic device. Results show that the transport velocity of fluid in the channel is 1.312 uL/s, and is affected by the fluid state in the inlet of the channel.

压电基板上微流体装置的快速原型制作

摘要 提出了一种在压电基板上快速制作微流控器件原型的新方法。透明塑料薄膜用于切割通道图案模具，并将其粘贴在玻璃上。聚二甲基硅氧烷 (PDMS) 填充在玻璃上并在烘箱中固化。从塑料模具上剥离后，PMDS 与带有叉指换能器的压电基板粘合。红墨水溶液用于验证微流体装置的功能。结果表明，流体在通道中的传输速度为1.312 uL/s，并且受通道入口流体状态的影响。
