In this paper, a model-independent adaptive PID control scheme is proposed for the angle control of electromagnetic scanning micromirrors. In this scheme, only using the input and output data of the micromirror, a model-free adaptive mechanism is designed to adjust the PID parameters online to adapt to the change of the micromirror characteristics due to the hysteresis exists in the micromirror. It makes the deflection angle of the micromirror can track the reference trajectory fast and accurately. Finally, the simulation results show that the proposed control method has achieved better control performance than PID control in controlling the deflection angle of the micromirror.

A synaptic phototransistor array achieved neuromorphic logical transformation based on 10cm diameter (4 inches) wafer scale IGZO synthesized by magnetron sputtering. The phototransistor in array had significantly favorable optoelectronic performance, which reached ~ 107 on/off ratio and 8.17×1014 Jones of specific detectivity. Neuromorphic logical transformation between ‘ON/OFF’ switch and ‘OR’ gate was demonstrated based on optoelectronic control of phototransistor. This work provided an effective way to simplified circuits integration for logical calculation and neuromorphic computing.

Ultrasonic-driven printing technology is widely used in bioprinting because of its high precision, good biocompatibility, and low cost. However, the conventional ultrasonic printing technology still has problems such as cross-contamination of bio-ink during storage, transportation, and processing, and cumbersome ink replacement process. Therefore, a new ultrasonic printing device is developed in this paper, which uses PZT plates as the driving element. And a fluid sub-system has been fabricated based on the self-made glass micro-nozzle, which is connected to the drive element using ultrasonic couplant gel. The separation of the fluid system and the drive system has been realized through the modular design, thereby realizing the rapid replacement of different inks and this relatively independent fluid system is of great benefit to better sealing and aseptic operation. In addition, a digital model is built to analyze its working mechanism. And an experimental system is established to characterize the performance of the device. The results show that the system can generate droplets stably and accurately, and the droplet volume can be controlled by the excitation voltage amplitude and pulse width.

In this paper, a nanosecond pulse laser is used to fabricate micro-channels on the Al2O3surface, and the effect of laser parameters (power, scanning speed, and scanning times) on micro-channel characteristics is investigated. Surface morphology, cross-section profile, and chemical composition are characterized by scanning electron microscope (SEM), confocal laser microscopy, and X-ray photoelectron spectroscopy (XPS). Results show that a series of phenomena such as melting, evaporation, flow, and resolidification occur during laser ablation, which lead to micro-channel structure and obvious heat-affected zone (HAZ) generated on the surface. Meanwhile, the laser parameters have significant effects on the micro-channel morphology by changing the surface energy accumulation. XPS results show that oxygen content increased and carbon content decreased after laser ablation, and a new aluminum-containing compound AlN was produced, which leads to the formation of partial cracks on the sample surface.

Re-entrant structures fabricated on the metal surface have a significant effect on the surface properties of metallic materials. It has attracted more and more attention due to its hydrophobicity, sound absorption, and anti-reflection property. This study proposed a method based on laser-assisted electrochemical deposition. First, microcolumn array substrates were prepared by laser etching. The substrate was prepared by laser etching, and subsequently the micro re-entrant structures were manufactured via localized electrodeposition under the tip effect. The volume deposition rate can reach $924.8 mumathrm{m}3/mathrm{s}$, and the static structure hydrophobic angle was 133° after electrochemical deposition, which is 18% higher than that after laser etching. It must be a new method and a new way to fabricate re-entrant structures on the metal substrate.

Aqueous Zn-based batteries have the advantages of low cost, large capacity, high power, environmental safety, and high energy density. Therefore, aqueous zinc-ion batteries have a wide application prospect in energy-storage devices. However, the growth of Zn dendrites become the most troublesome problem affecting the lifetime of Zn batteries, which inhibits the further development of Zn-based batteries. A simple method is reported to regulate the nucleation of zinc by laser-induced graphene, so that the formation of zinc dendrites can be inhibited. In this work, a 3D composite structure containing laser-induced graphene (LIG) and polyimide (PI) was constructed on the zinc surface by processing PI films with laser. The 3D structure formed by laser treatment has a large specific surface area and abundant micropores, which can cause uniform distribution of zinc ions. More importantly, the large number of defects in LIG significantly reduced the nucleation overpotential of Zn, and mitigates Zn dendritic growth.

In order to improve the wear resistance of 5083 Al-Mg alloy super hydrophobic surface. A predetermined pattern of insulating mesh is attached to the metal substrate to electrochemical reactions occur on the metal surface not covered by the insulating layer, resulting in a superhydrophobic surface with a surface frame structure. One-factor experiments were conducted to investigate the effects of processing time in electrochemical etching on surface wettability and mechanical robustness of aluminum and magnesium alloys. AA5083 Al-Mg alloy was electrolytically machined with square mask in 0.4 mol/L NaCl solution as electrolyte, and its surface was superhydrophobic. Linear wear experiments were carried out and the hydrophobic property of contact angle 150.1° rolling angle 12.5° was maintained for 7 minutes after wear exceeding 25 cycle processing parameters of 1 A/cm2. SEM electron microscope image analysis of electrolytically processed aluminum and magnesium alloy surface shows that the mask electrolysis method can effectively improve the wear resistance of the superhydrophobic surface, while the frame structure produced by the mask electrolysis will not destroy the hydrophobic property of the original surface.

A molybdenum disulfide $(mathbf{MoS}_{2})$ based hydrogen peroxide $(mathbf{H}_{boldsymbol{2}}mathbf{O}_{boldsymbol{2}})$ memsensor (a memory sensor or a sensor with memory) is designed as a passive one oriented to be carried by microrobots, where a local power supply is hardly be available. The sensor has a crossbar configuration and is microfabricated of $mathbf{Au}/mathbf{MoS}_{boldsymbol{2}}/mathbf{Au}$ with a junction area of 0.25 $boldsymbol{mu} mathbf{m}^{boldsymbol{2}}$. It functions with physical absorption of oxide ions on the surfaces or between layers and/or chemical oxidation on the edges and defects of $mathbf{MoS}_{boldsymbol{2}}$. Due to its nature of irreversible structure, calibration has been done at a lower concentration of $mathbf{H}_{boldsymbol{2}}mathbf{O}_{boldsymbol{2}}$ and confirmed at a higher one presetting a scenario that the sensor will be carried out by a microrobot being sent to a certain region for sensing $mathbf{H}_{boldsymbol{2}}mathbf{O}_{boldsymbol{2}}$ with an intermediate concentration and collected back for understanding the information where the microrobot has been staying. Experiments show that the proposed calibration and sensing method has an acceptable resolution in the range of 200 nmol/L to 1200 nmol/L.

Thermal damage to osteocytes is a common problem in orthopedic surgery, and vibration-assisted milling (VAM) can remove bone materials efficiently and with low damage, which is of great significance to improve the success rate of surgery. However, the mechanism of heat transfer during vibration milling is not clear, so it is necessary to study the mechanism of heat generation and heat transfer during vibration milling. Based on the heat generation mechanism of vibration milling bone material, a temperature model of bone material was established, and the correctness of the model was verified by finite element simulation experiments. The experimental results show that vibration cutting can effectively suppress heat generation and reduce thermal damage area compared with conventional cutting.

The excellent wettability of superhydrophobic materials means they have a wide range of potential applications. However, there are still urgent problems in corrosion resistance to be solved. In this paper, durable superhydrophobic aluminum samples were prepared by laser texturing and silanization. This superhydrophobic coating exhibits certain superhydrophobic stability with a maximum Water Contact Angle (WCA) of 153.7° and a Roll Angle (RA) of 4.5°. The corrosion resistance of superhydrophobic aluminum surface in 3.5 wt.% NaCl solution was investigated using Electrochemical Impedance Spectroscopy (EIS) and Potentiodynamic Polarization (PDP) technique. Meanwhile, the chemical stability of superhydrophobic aluminum surface in NaCl solution at different times was evaluated. The results show that the superhydrophobic coating has good corrosion resistance in NaCl aqueous solution.
