Patent ID: 8603413

Claim:
A biochip for handling liquid droplets comprising: a substrate, comprising an array of 2 n lines of electrodes, n being an integer number, each line of electrodes having N electrodes, N being an integer number, wherein n >1 and n≦N, each of said lines of electrodes being controllable to displace one droplet of liquid through electrowetting from one of said N electrodes to another one of said N electrodes; a plurality of 2n line conductors; each line of said 2 n lines of electrodes comprising a group of n electrodes, each electrode of said group of n electrodes of each of said lines of electrodes being connected to one of said 2n line conductors; each one of said plurality of 2n line conductors being connected to 2 n−1 electrodes in the array of 2 n lines of electrodes, each of said 2 n−1 electrodes being in a different one of the 2 n lines of electrodes; and a plurality of selector units, each of said line conductors receiving a signal through one of said plurality of selector units.
