Inspired by the flexible joints of humans, actuators containing soft have been developed for various applications, including grippers, artificial muscles, and wearable devices. However, integrating multiple microjoints into robots at micrometer scale to achieve multi-deformation modalities remains challenging. Here, we propose a two-in-one femtosecond laser writing strategy fabricate composed hydrogel metal nanoparticles, develop multi-joint microactuators with (>10), requiring short response time (30 ms) low actuation power (<10 mW) deformation. Besides, independent joint deformation control linkage deformation, co-planar spatial linkage, enables microactuator reconstruct variety complex human-like modalities. Finally, as proof concept, collection microcargos different locations is achieved double-joint micro robotic arm. Our will bring many potential application opportunities in microcargo collection, microfluid operation, cell manipulation.
