Abstract

Official abstract text for this publication.

Liquid droplet manipulation instrument has electrode array for inducing movement of a droplet by electrowetting, substrate supporting the array and control with electrode selector connected to a voltage control. The selector selects each electrode and provides each with a controlled voltage. The control includes central processing unit for providing the selected electrode with an individual voltage pulse which is a drive voltage or a ground voltage or a stop voltage. The control defines a path for movement of a liquid portion of a larger volume that covers more than one electrode by the simultaneous selection of a group of two or more subsequent drive electrodes and to provide each selected drive electrode with a drive voltage pulse along the path. The control simultaneously provides a group of two or more electrodes adjacent to or identical with the pulsed drive electrodes, with a ground or stop voltage pulse.

First claim

Opening claim text (preview).

What is claimed is: 1. A liquid droplet manipulation instrument ( 20 ), comprising: (a) at least one electrode array ( 21 ) for inducing a movement of a liquid droplet ( 19 ) by electrowetting; (b) a substrate ( 22 ) supporting the at least one electrode array ( 21 ); and (c) a control unit ( 23 ) comprising at least one electrode selector ( 34 ) connected with at least one voltage control ( 29 ), the at least one electrode selector ( 34 ) being accomplished to individually se…
