Abstract
An object is to measure a mechanical property of a fluid at a temporal resolution of at least 100 [μs]. Therefore, a method comprising: causing a dropletto fly by ejecting a fluid to be measured from a nozzleas the droplet; generating an electric field in a space around a flight pathof the dropletby applying a voltage to an electrode arranged in the vicinity of the flight path; deforming the dropletin a way of contactless deformation with a dielectric force induced by the electric field; and measuring a mechanical property of the fluid based on temporal variation of deformation state of the dropletafter deforming the droplet
