摘要:
An electrotransport device for transdermal drug delivery has a number of electrodes and driving circuitry for supplying driving signals to the number of electrodes. The electrodes are connected to the driving circuitry in rows and columns. The driving circuitry has row driving circuitry for supplying a row signal to a row of electrodes, and column driving circuitry for supplying a column signal to a column of electrodes. A predetermined electrode is individually addressable by supplying a row signal to a corresponding row of electrodes and a column signal to a corresponding column of electrodes.

The Invention concerns to a micro-actuator device for the use in biochip or bio-system. In order to achieve a micro-actuator device for the use as a micro pump in biosensors or bio-systems, or at least bio-chips, by which the actuation can be steered very precisely and effective, the solution is that the micro actuator consist of a photosensitive actuator element (1), which can be deformed from a reversal basic-form into an activated deformation form by photonic activation of a light source (3, 4, L1, L2) in order to generate with this controlled movement a defined flow in a gas or a liquid.
