摘要

本文报道了一种基于压阻悬臂阵列上液滴共振振动的粘度测量方法。我们证明了小液滴(3μL)的粘度可以通过液滴振动自由衰减过程中悬臂梁输出的衰减率来估计。用水-甘油溶液对不同粘度的液体样品进行了估计。

A viscometer based on vibration of droplets on a piezoresistive cantilever array

This paper reports a method to measure viscosity based on the resonant vibration of droplets on a piezoresistive cantilever array. We demonstrate that viscosity of small droplets (3μL) can be estimated from the attenuation rate of the cantilever output during free-decay of the droplet vibration. The estimation for liquid sample with different viscosity using water-glycerol solutions were carried out.
