Patent ID: 8795501

Claim:
A dielectrophoretic particle concentrator, comprising: a first substrate, as a rectangular bar having a longitudinal direction extending along a first direction; a set of detection electrodes in a bar structure, disposed on the first substrate, extending along a second direction perpendicular to the first direction; a second substrate, as a rectangular bar having a longitudinal direction extending along the first direction and located over and separate from the first substrate in parallel; a protrudent structure, disposed on the second substrate and protruded towards the first substrate, wherein a top portion of the protrudent structure forms a line structure extending along the second direction and adjacent to the set of detection electrodes, wherein the line structure along the second direction is also parallel to the first substrate with a separate distance to form a space; and a set of edge wall structures, integrated with the first substrate and the second substrate so as to form a pipe structure to enable a fluid flowing through the space between the line structure of the protrudent structure and the first substrate from an end to another end.
