摘要：

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 (3 mu L) can be estimated from the attenuation rate of the cantilever output during free-deeay of the droplet vibration. The estimation for liquid sample with different viscosity using water-glycerol solutions were carried out.
