Abstract
Official abstract text for this publication.
According to one aspect of the present disclosure, a control-engaged electrode-driving method for droplet actuation is provided. The method includes, a first pulse is provided to a first electrode for kicking off a droplet till a centroid of the droplet reaching a centroid of the first electrode. A second pulse is provided to a second electrode when a leading edge of the droplet reaching the second electrode.
First claim
Opening claim text (preview).
What is claimed is: 1 . A control-engaged electrode-driving method for droplet actuation, comprising: providing a first pulse to a first electrode for kicking off a droplet till a centroid of the droplet reaching a centroid of the first electrode; and providing a second pulse to a second electrode when a leading edge of the droplet reaching the second electrode. 2 . The control-engaged electrode-driving method for droplet actuation of claim 1 , wherein the first electrode and the second electrode are coplanar. 3 . The control-engaged electrode-driving method for droplet actuation of claim 1 , wherein the first electrode and second electrode are located in an electrowetting-on-dielectric (EWOD) device. 4 . The control-engaged electrode-driving method for droplet actuation of claim 2 , wherein the EWOD device comprises: a first plate; a second plate facing the first plate; and the droplet in between the first plate and the second plate; wherein the first electrode and a second electrode are on the second plate. 5 . The control-engaged electrode-driving method for droplet actuation of claim 3 , wherein the EWOD device further comprises a gap between the first plate and the second plate, wherein the gap in the range of 1 μm to 1000 μm. 6 . A control-engaged electrode-driving method for droplet actuation, comprising: providing a first voltage to a first electrode for kicking off a droplet till a centroid of the droplet reaching a centroid of the first electrode; and providing a second voltage to a second electrode when a leading edge of the droplet reaching the second electrode. 7 . The control-engaged electrode-driving method for droplet actuation of claim 6 , wherein the first voltage and the second voltage have the same mathematical value. 8 . The control-engaged electrode-driving method for droplet actuation of claim 6 , wherein the first electrode and the second electrode are coplanar. 9 . The control-engaged electrode-driving method for droplet actuation of claim 6 , wherein the first electrode and second electrode are located in an electrowetting-on-dielectric (EWOD) device. 10 . The control-engaged electrode-driving method for droplet actuation of claim 9 , wherein the EWOD device comprises: a first plate; a second plate facing the first plate; and the droplet in between the first plate and the second plate; wherein the first electrode and a second electrode are on the second plate. 11 . The control-engaged electrode-driving method for droplet actuation of claim 6 , wherein the EWOD device further comprises a gap between the first plate and the second plate, wherein the gap in the range of 1 μm to 1000 μm.
