A 2DAMA project aims on investigation and development of an innovative and smart micro-actuation system based on a 2D array of cooperative and multi-stable hybrid levitation micro-actuators. Through implementing multidisciplinary and innovative approaches based on multi-stable mechanisms, array-based and coherent cooperative actuation, new capabilities such as levitation of arbitrary shaped micro-objects, performing their linear and angular positioning and transportation within a desired area in the proposed actuation system are achieved. Implementation of these approaches is executed by means of a novel hybrid levitation actuator as the basic and integrated element into the proposed actuation system, having newly improved performances, which are characterized by a small operation current (less than 10mA) and low operation temperature (it is comparable to the ambient temperature). The proposed micro-actuation system provides a new paradigm of solution for emerging complex tasks, which require: a considerably extended motion range and wider operational capabilities, transportation and manipulation of micro-objects with a higher accuracy and faster time of actuation, a significant reduction of the dissipated energy, preventing a contact with harmful surfaces and the ensured long lifetimes.
