Beschreibung
Zusammenfassung:	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.
