20.500.12556/DKUM-40172 PRIJEMALO ZA OBJEKTE V MIKRO IN NANOMETRSKEM PODROČJU GRIPPER FOR OBJECTS IN MICRO- AND NANO-SCALE V okviru doktorske disertacije je bilo potrebno razviti prijemalo, ki bo sposobno manipulirati z delci v mikro- oz. celo nanometrskem področju. Kot raziskovanja vreden princip se je izkazalo ledno prijemalo. Pri dosedanjih lednih prijemalih se je kot medij za tvorjenje ledu uporabljala tekoča voda, kar onemogoča uporabo zelo ostrih konic (s krivinskim radijem nekaj 100 nm) in manipulacijo objektov velikosti pod nekaj 100 μm. Prijemalo, razvito v okviru tega doktorskega dela, za gradnik ledu uporablja vodno paro v vakuumskem okolju pod njeno trojno točko, s čimer se znebimo tekoče faze. Izkazalo se je, da prijemalo deluje kot konica s spremenljivo kontaktno površino, s čimer se spreminja velikost sile med objektom in konico, kar omogoča prijemanje in spuščanje. Prijemalo omogoča manipulacijo objektov, z velikostmi nad 840 nm z zgrajenim sistemom. Ta vrednost pa ne predstavlja meje pri manipulaciji nanometrskih objektov. The doctor thesis presents the development of the gripper which is capable of manipulating objects in the micro- or even in the nano-scale. Principle of gripping with ice proved itself as worth of the further investigation. State of the art ice grippers use liquid water as the ice formation media, which makes use of the very sharp tips (apex diameter of couple of 100 nm) and manipulation of the objects under the size of couple of 100 μm impossible. Ice gripper developed within this framework uses water vapour under its triple point for the ice formation media, which eliminates the presence of the liquid water. The gripper has proved itself to operate as the variable surface gripper, where the contact area between the tip and the object is varied, what makes the gripping and releasing possible. The developed gripper has shown the capability of manipulating objects down to 840 nm in size. This value still does not present the lower limit where the gripper could be deployed. mikro manipulacija mikro prijemalo ledno prijemalo mikro sestavljanje nano prijemalo. micro manipulation micro gripper ice gripper micro assembly nano gripper. true true false D.
