An Archimedes planar spring (APS) with lower stiffness and compact structure is designed for a microforce actuator. The theoretical analysis of the APS stiffness is carried out using the Castigliano’s theory and linear elasticity theory of material mechanics. To optimize the structure, the Finite Element Analysis (FEA) is utilized. The theoretically calculated results using the derived stiffness formula agree well with the FEA simulation results. Meanwhile, the dynamic characteristics are simulated, which conforms the stable and reliable properties. The microforce is generated by an electromagnetic system, which is mainly composed of the coil solenoid, permanent magnet and APS. The designed system has a good characteristics with current resolution of 0.2 mA, basing on the experiments. In addition, the conversion rate can be obtained 3.53 µN/mA from the curve between electromagnetic force and the input current.

Flapping wing micro air vehicles (MAVs) take inspiration from natural insects and small birds. Reducing its size is a trend in development. Bioinspired from hindwings of the Asian ladybeetle, a design scheme of bionic deployable wings is put forward in this paper. The deployable movement is achieved by the mechanical structure of two four-bar-linkages, which learn from the behaviors of the folded motion of the beetle’s hindwings. The links are hollow structures bioinspired by hollow tubular structural of vein of the beetle hindwings, which can reduce the mass and improve the maneuverability in flight. Under uniform load and bending moment, the total deformation, equivalent stress and strain of deployable wings are investigated by the finite element analysis (FEA). The simulation shows that their mechanical properties can have beneficial effect on the flight.

Nanostructures and nanomaterials provide promising building blocks for plasmonic manipulation and applications. To significantly combine the nanostructures with nanomaterials, we have investigated the mid-infrared (MIR) plasmonic response mimicking electromagnetically induced transparency (EIT) in a graphene nanowaveguide system, consisting of the graphene sheets coupling with double graphene ribbons parallel to each other. The results demonstrate that the EIT-like spectral profile and position are strongly dependent on the graphene ribbon width. The resonant spectral width can be effectively controlled by adjusting the coupling strength (gap distance) between the graphene ribbons. Especially, the active tunability of spectral profile can be realized by altering the chemical potential ( or Fermi level) of graphene ribbon. The finite element method (FEM) numerical simulations agree well with the results theoretically calculated by the coupled mode theory (CMT). Our results will offer a new pathway toward the realization of graphene-based active plasmonic controlling and devices.

Ti50Ni25Cu25 alloy (at.%) produced by melt-spinning technique in the form of layered amorphous-crystalline ribbons at around 40 microns of thickness was used as the base material to fabricate microtweezers (microgrippers). The obtained structural composites were capable of executing reversible bending deformations in a heating/cooling cycle. A series of microtweezers with the gap adjustable in the range from 5 to 120 μm was fabricated. The width of the gripping parts composed 400-500 μm and their length was from 650 to 1300μm depending on the gap value. Optical and scanning electron microscopes were used to monitor the operation of the tweezers. The optimum control parameters provide the response time about 1 s by the operation both in the environment and in vacuum. The complete process of manipulating (gripping - holding - moving – releasing) the carbon fibers at the diameter 10 to 20 μm with using the fabricated device was demonstrated. The microtweezers can be used for the control of microobjects of various origins, in particular nanotweezers in the systems for manipulation of nanoobjects.

The wings of dragonfly have been extensively researched for designing of Micro Air Vehicles (MAVs). The cross-sectional structure of the veins will be influent to flight characteristics of dragonfly. In this paper, elliptical and circular tube structures are found in vein by fluorescence microscope. Based on the results, model I and model II with elliptical and circular cross-sectional structural vein are established, respectively. By computational fluid dynamics (CFD) simulation, the drag coefficient, lift coefficient and lift-to-drag ratio of model I and model II are obtained. It is shown that model I can generate greater lift and produce less resistance. The lift-to-drag ratio of model I is larger 50% than that of model II at an angle of attack of 60 degrees. It will be provided a bioinspiration to design a bionic flapping MAV.

In the report the physical basis of the development of electrical nano-contacts for bottom-up nanointegration are studied. For the fabrication of the electrical nano-contacts it is proposed to use the electromigration of micro - and -nano-drops of metals and 3D mechanical nanomanipulation of the nanowires. Nano-manipulation is provided by the usage of nanotweezers, produced from shape memory alloy composite. The process of the melting of the micro-wires was studied under the action of laser radiation and heating.

The paper is focused on combining Potts Kinetic Monte Carlo method (KMCM) with Discrete Element method (DEM) to analyze the porous transducer sintered by glass microspheres. Effects of parameters including particle size distribution (PSD), mean particle size and sintering temperature, are studied by analyzing relative density and permeability of the porous transducer reconstructed based on its production process. Simulation results show that porous transducer made from glass microspheres with larger mean particle size and narrower PSD performs larger permeability. Meanwhile, higher sintering temperature can speed up the densification rate during sintering process. The above results can be applied to guide the fabrication process of porous transducer.

In this paper, the coupling and conversion behaviors of all the polarization states of guided-mode in an SOI (Silicon on Insulator) curved waveguides are investigated with Optiwave FDTD simulations and experiments. Research shows, the conversion efficiency between two transverse polarizations, from Ex to Ey of SOI curved waveguide is lower than the conversion efficiency from one polarization Ex to the horizontal polarization Ez. The experimental results are agreeable with the FDTD simulations. Thereby, it is possible to realize the polarization state conversion and the TE/TM-mode transmission of the guided-mode in an SOI waveguide device in applications.
