This invention relates to the fields of microelectronics manufacturing and precision surface engineering, comprising: a laser unit for generating and controlling a laser beam, an electrodeposition unit for providing an electric field, a detection unit for real-time online monitoring of coating thickness and edge contour, and a control unit for dynamically adjusting laser and electrochemical parameters based on monitoring data. The process steps include: substrate pretreatment, plating solution preparation, intelligent matching of initial parameters based on the target linewidth, adaptive closed-loop deposition, and post-processing. During deposition, by real-time detection of coating thickness and edge overflow, the control unit dynamically adjusts the laser single-pulse energy, scanning speed, and current density to compensate for process disturbances. This invention solves the problems of low pattern accuracy, poor edge localization, and weak process adaptability in existing technologies, achieving high-precision micro-pattern fabrication with linewidth accuracy controlled within ±1% and edge overflow ≤0.5μm, thus improving process stability and product yield.

This invention discloses a directional sound-emitting foldable display screen, comprising a vibrating layer and a non-vibrating layer. The vibrating layer includes a foldable screen and a vibrating substrate layer, which is integrally formed using 3D printing and disposed on the lower end surface of the foldable screen away from the user. The non-vibrating layer includes a non-vibrating substrate layer, an insulating layer, and a micro-patterned layer. The insulating layer is disposed on the upper end surface of the non-vibrating substrate layer near the vibrating layer. The micro-patterned layer consists of multiple insulating bumps formed on the upper end surface of the insulating layer near the vibrating layer, and is integrally formed by using 3D printing, slot coating, or exposure and development processes to form a resin layer internally doped with alumina nanoparticles. This invention achieves full foldability of the directional sound-emitting foldable display screen while improving the overall operational reliability of the product, and has advantages such as significantly shortened development cycle, lower cost, wider applicability, and higher precision and flexibility.

A passive, non-electronic wearable device (100) provides real-time visual biofeedback of soft tissue (130) elongation to prevent overstretch injuries. The device (100) comprises an elastic base layer (110) having a first periodic micro-pattern (112) and an elastic overlay layer (120) having a second periodic micro-pattern (122). The layers are superimposed and configured to elongate synchronously with the underlying soft tissue (130). When the soft tissue (130) reaches a predetermined biomechanical strain threshold, such as 22 to 34 percent elongation corresponding to a pre-pain safety limit, the relative geometric displacement between the first micro-pattern (112) and the second micro-pattern (122) generates a macroscopic Moiré interference pattern (140). This optical-mechanical interference visually exposes a hidden warning indicator (114) without requiring electronic components, power sources, or external sensors. The system can be integrated into athletic garments or worn as a standalone band.

Security element transfer materials for transferring security elements have a microoptical authenticity feature to an article of value. The microoptical authenticity features create an optical effect by interaction of a first microoptical arrangement having focusing elements with a second microoptical arrangement having micromotif elements. The security element transfer material has a temporary carrier in the form of a layer composite material. The temporary carrier consists of a first temporary carrier substrate and a second temporary carrier substrate, which may be inextricably adhesive-bonded by means of an adhesive layer. The outline shapes of the security elements to be transferred are incised or have been precut. The second temporary carrier substrate is not cut, such that the temporary carrier can be separated off as a complete carrier layer composite. A permanent carrier is bonded inextricably to the microlenses. A transfer adhesive enables adhesion to the final substrate of the article of value.
