Scientists develop a new technique for using lasers to create 'dancing' microrobots with movable joints that have a wide variety of applications.
joints that can "realize linear/curvilinear crawling, walking, turning, and jumping by laser-inducing," as the study proposes. Another use would be to create flexible hands with multiple joints as an aid to disabled people. This would allow them to grip different kinds of objects., “Flexible joints exist widely in natural organisms, and the cooperation between joints leads to elaborate movements and the realization of variable functions.
The particulars of the method involved the femtosecond laser dual-function fabrication strategy that utilizes asymmetric two-photon polymerization to make hydrogel joints. Laser reduction was used to locally deposit silver nanoparticles into the joints.reached out to the team from the University of Science and Technology of China for more insight on their accomplishment. In an email exchange, Xin Chen of USTC elaborated on why they chose to create dancing microrobots.
With regards to the possible applications of the technology, the representative of the research team shared that the so called two-in-one femtosecond laser processing technology could fabricate multi-modal microstructures. The scientists believe that the manufacturing technology they are developing could be used to create technical tools for the fields of microcargo manipulation, microfluidic chips, and microoptics.
