The invention discloses an allergen skin pricking detection device with a skin state recognition function. The allergen skin pricking detection device comprises a bottom plate, a scanning assembly, a control assembly, an infrared marking assembly, a pricking assembly and a pricking liquid storage assembly, the fixing rod is arranged on the bottom plate, the first end of the lifting plate is in sliding connection with the fixing rod, and the camera and the structured light 3D scanning equipment are both arranged on the lifting plate; the infrared marking assembly is arranged at the second end of the lifting plate; the pricking assembly comprises a mechanical arm, a supporting plate, a movable head and a plurality of pricking needles, the mechanical arm is arranged on the bottom plate, the supporting plate is arranged on the mechanical arm in a liftable mode, the movable head is rotationally arranged on the supporting plate, and the pricking needles are evenly distributed on the movable head at intervals; and the pricking liquid storage assembly is communicated with the pricking needle. According to the method, the coordinates of the pricking area can be automatically identified and generated, abnormal skin such as ulceration, scars and hard joints can be avoided, infection, bleeding or misjudgment conditions are avoided, the pricking position is dynamically adjusted according to the actual state of the skin, and the detection efficiency is improved.

The invention relates to a polyvinyl alcohol / graphene oxide composite hydrogel patch as well as a preparation method and application thereof.According to hydrogel, graphene oxide nanosheets are introduced into polyvinyl alcohol, a brick-mud structure similar to a pearl layer is obtained through evaporation self-assembly, an interface is further reinforced through covalent crosslinking, and the composite hydrogel patch is prepared. And when the hydrogel patch is used for skin wound nursing, rigid and tough synergism effectively adjusts wound edge stress concentration and resists long-term mechanical stress disturbance, so that formation of abnormal skin scars induced by dynamic mechanical stimulation is inhibited. The invention provides a hydrogel patch which can obviously shield stress and is stable for a long time, and the hydrogel patch is suitable for medical application such as wound nursing in highly movable or curved skin areas.

This invention relates to an antibody specific to LDH1 of *Lactobacillus plantarum*, and compositions or kits containing this antibody for detecting *Lactobacillus plantarum* or diagnosing skin conditions. The monoclonal antibody of this invention exhibits very high reactivity to antigens. In particular, by combining two antibodies with different complementary determinant regions (CDRs) as a capture antibody and a detection antibody, antigens can be detected rapidly and accurately even at low concentrations, thus enabling applications in rapid self-diagnostic kits, etc. Using this monoclonal antibody, the proliferation status of *Lactobacillus plantarum* on the skin surface can be visually confirmed, thereby diagnosing abnormal skin conditions, predicting the incidence and persistence of related diseases, and ultimately determining subsequent treatment plans.

This invention relates to the interdisciplinary field of artificial intelligence and skin health management, specifically disclosing an AI-powered facial blemish recognition and care suggestion system. The system includes an image acquisition device, a facial blemish recognition module, a traditional Chinese medicine facial diagnosis knowledge graph module, an internal cause analysis module, and a comprehensive care suggestion generation module. Through deep learning, it identifies facial acne, pigmentation, and abnormal skin texture; combines traditional Chinese medicine facial diagnosis theory to establish a mapping relationship between facial areas and organ functions; integrates multi-source data to infer endogenous causes; and generates multi-dimensional suggestions covering external care, diet, sleep, and emotional management. This invention, through the above technical solution, achieves a cognitive leap from surface recognition to internal cause analysis, improving the scientific rigor, relevance, and long-term effectiveness of care suggestions.

This invention discloses a numerical simulation system and method for thermoelectric materials in electronic skin, belonging to the field of finite element simulation technology. The system simulates the thermal management capabilities of electronic skin under extreme environments by constructing a three-dimensional thermoelectric coupling model, achieving effective heat transfer within the simulated robot and intelligent regulation of skin temperature. The system comprises a composite wire structure formed by alternating copper wires and bismuth telluride cylindrical particles, utilizing the thermoelectric effect to achieve directional heat transfer. By setting a temperature switching function, the system can automatically adjust the heat source and current according to the skin temperature, achieving low-temperature heating and high-temperature heat dissipation functions. Simulation results show that the system can adjust abnormal skin temperature to the normal range (29–30ºC) in a short time, with fast response time and high adjustment accuracy, effectively solving the problem of limited effectiveness of traditional heat dissipation methods in enclosed spaces.
