Abstract
In the present study, we have developed a new miniaturized optical viscometer, namely MOVS (Micro Optical Viscosity Sensor), which is applicable to the noninvasive, high speed, small sample volume, in situ and in vivo measurement of a liquid sample based on laser-induced capillary wave (LiCW) technique in both medical and industrial fields. In this paper, the fabrication of prototype MOVS chip for the first time and the discussion of the validity of the viscosity measurement were reported. Preliminary measurement using distilled water and sulfuric acid were demonstrated, and nanosecond order high speed damping oscillation signals were successfully observed.
