Abstract
A particle transporter based on travelling-wave dielectrophoresis is provided. The particle transporter includes a plurality of turn-around electrodes. The turn-around electrodes are disposed on a substrate and arranged in a fan shape. The turn-around electrodes provide an arc channel for transporting a plurality of particles. Wherein, the turn-around electrodes are not connected to each other, and neighboring sides of any two adjacent electrodes of the turn-around electrodes are approximately parallel.
Claims55
A particle transporter, comprising:
- a power supply unit, for providing power signals to electrodes in the particle transporter;
- and
- a plurality of turn-around electrodes, disposed on a substrate, and arranged in a fan shape to provide an arc channel for transporting a plurality of particles, wherein the turn-around electrodes are not connected to each other, and neighbouring sides of any two adjacent turn-around electrodes in the turn-around electrodes are approximately parallel.
A particle transporter, comprising:
- a power supply unit, for providing power signals to electrodes in the particle transporter;
- a common electrode, disposed on a substrate;
- a plurality of left switch electrodes, disposed on the substrate along a first straight-line direction and disposed adjacent to a first end at one side of the common electrode, wherein the left switch electrodes are parallel to the common electrode, and provide a left switch channel to transport a plurality of particles;
- and
- a plurality of right switch electrodes, disposed on the substrate along a second straight-line direction and disposed adjacent to a second end at the side of the common electrode, wherein the right switch electrodes are parallel to the common electrode and provide a right switch channel to transport the particles,
- wherein a common end of the left switch channel and the right switch channel is formed at the common electrode.
