Abstract: The present invention provides a method of on-line rapid fluid density measurement using a piezoresistive micro-cantilever, the present invention can achieve on-line measurement without changing the existing device; more importantly, without acquiring the resonant frequency of the cantilever in fluid to be detected, thus remarkably reducing measurement time, and guaranteeing the real on-line rapid measurement. By using the method of the present invention, measurement of the density of fluid to be detected by a calibrated piezoresistive micro-cantilever may be achieved within seconds or even shorter.
