Curved Electrode Micro Particle Separator

The device segments the sample flow into distinct regions using a sheath flow that creates a laminar flow pattern. The sample stream is divided and directed through specific pathways that separate microorganisms from dust particles based on their different physical properties, allowing reliable analysis by isolating target particles from interfering contaminants

The invention replaces complex mechanical separation systems with an electrostatic separation mechanism. By applying electric fields through electrodes, the device exploits dielectrophoresis to separate particles based on their dielectric properties, eliminating the need for complex mechanical moving parts while achieving reliable particle separation

The device employs hydraulic principles through the use of sheath flow - a laminar fluid flow that envelops the sample stream. This fluid dynamic approach creates a controlled environment where particles are separated based on their response to electric fields while being carried by the flow, achieving effective separation without complex mechanical structures

The invention changes the physical parameters of the separation process by utilizing dielectrophoresis - the movement of particles in non-uniform electric fields based on their dielectric properties. By adjusting electric field parameters through the electrode configuration, the device achieves selective separation of microorganisms from dust particles, improving separation effectiveness while maintaining relatively simple device structure
