Magnetic remote actuation of soft materials is attractive for applications such as transforming materials and medical robots. However, due to manufacturing limitations, microscale magnetoactive devices are scarce and light-based additive manufacturing methods, despite achieving microscale resolution, struggle with particle-induced light scattering. Moreover, large hard-magnetic microparticles restrict ultimate feature sizes and deformation of soft-magnetic nanoparticle composites […]
In this work, we demonstrate the fabrication as well as immediate application of 3D printed spiral phase plates on the ends of FC/PC fiber adapter ferrule tips using a NanoOne 1000 two-photon polymerization 3D printer from UpNano. The spiral phase plates were fabricated to alter the orbital angular momentum of incoming light, and a direct […]
Shape memory polymers capable of recovering their original form after deformation are highly desirable for applications in soft robotics, biomedical engineering, and microfabrication. However, integrating shape memory properties into 3D-printed microstructures with ultra-low mass remains a challenge, as most existing systems lack sufficient resolution or mechanical robustness at the microscale. In this study, a poly(ε-caprolactone)-based […]
Optically driven robotic actuators are synthetic materials capable of reversible shape-morphing under the control of incident light.Conventional approaches typically require a favorable illumination condition, that is small incidence angle excitement coveringlarge sample area, which poses challenges for optical integration and applicability in optically restricted environments. Here,we present a method that utilizes two-photon polymerization laser-printing of […]
Resonant metallic structures are crucial for telecommunications, biosensors, and microrobotics. However, it presents challenges in obtaining high-quality metallic structures using traditional microfabrication methods. Here, we present a rapid prototyping method that combines two-photon polymerization and electrochemical etching to achieve metallic cantilevers of submillimeter sizes for Micro-Mechanical Oscillators (MMOSs). A mask with cantilever designs for selective […]
