我们展示了一种新的光学微流体压力测量平台。压力传感器作为焦距随压力变化的可调谐微透镜工作。我们表明,气动透镜阵列可用于执行敏感的多路复用的微流体通道中的压力测量。
We demonstrate a novel optical pressure measurement platform for microfluidics. The pressure sensors operate as pneumatically-tunable microlenses whose focal lengths vary with pressure. We show that pneumatic lens arrays can be used to perform sensitive multiplexed pressure measurements in microfluidic channels.
