Thus, improving the degree-of-freedom on the fabrication of micro structure has been in focus. Compared to the complex fabrication and low degree-of-freedom on the traditional MEMS-3D-structure, we develop a series fabrication method of conductive 3D direct-write structure, which integrates the different conductive materials and micro-scale MEMS-structure for the structure with low-roughness of surface、high-strength of mechanical、high-complexity. In the research, the application of this fabrication will be introduced such as micro electromagnetic energy generator, or miniaturized electro-thermal grippers. The conductive 3D processing method is successfully utilized on the micro energy generators and micro actuators from the results. With different materials, we can design different dimensions, shapes and applications for the structure. With the benefits of workable in general environments, simple fabricating process, and wide range of material selection, we provide a better substitute option comparing to the traditional semi-conductor fabricating process.
