Abstract
A technique, including a system and a method, for measuring a fluid property using a piezo-actuated fluid dispenser, is disclosed. The technique includes generating a pressure wave in a channel in the piezo-actuated fluid dispenser using a piezo element, detecting, using the piezo element, a residual pressure oscillation in the channel caused by the generating, obtaining a resonance frequency of the pressure oscillation, and determining, using the resonance frequency, the fluid property.
