Title:
METHOD FOR MEASURING PARTICLES IN SOLUTION AND DEVICE FOR PERFORMING SAME
Document Type and Number:
WIPO Patent Application WO/2023/177044
Kind Code:
A1
Abstract:
The present invention relates to a method for measuring particles existing in a solution. A device for measuring particles according to the present invention comprises: a power supply unit for applying a voltage; a chip having a plurality of electrodes sequentially arranged on a fine flow path through which a fluid passes; a circuit unit on which at least a portion of a bridge circuit is printed to form a predetermined electrical state with the plurality of electrodes formed on the chip; and a measurement unit for measuring a change of an output signal of the bridge circuit caused by particles in the fluid passing through the fine flow path, wherein the power supply unit applies a voltage to the circuit unit. According to the present invention, fine particles in a solution can be accurately measured using a change of an electric signal. In addition, properties of the fine particles can be more accurately measured using the magnitude and time of the change of the electric signal.
