Speech Title:  Non-invasive sweat creatinine detection system integrated with Zn-Ni bimetallic MOF flexible sensor and biomimetic microfluidic chip

Abstract: Non-invasive and real-time creatinine detection technologies are in urgent need for the early screening of chronic kidney disease (CKD). Conventional detection methods suffer from drawbacks such as invasiveness, long detection cycles and the inability to achieve real-time monitoring, while existing sweat creatinine sensors are also confronted with bottlenecks including poor selectivity, insufficient stability and the reliance of microfluidic systems on external driving devices. For the first time, this study constructed a non-invasive sweat creatinine detection system integrating a Zn-Ni bimetallic MOF-based flexible sensor and a biomimetic microfluidic chip, providing a novel technical solution for the non-invasive, real-time and accurate monitoring of renal function. Taking laser-induced graphene (LIG) as the flexible substrate, the sensor was fabricated by compositing Zn-Ni bimetallic MOF synthesized via a room-temperature stirring method with carboxylated carbon nanotubes (COOH-CNT). By virtue of the bimetallic synergistic effect and the advantages of multi-material composite, the integration of "recognition-conduction-support" was realized. The sensor exhibited favorable segmented linear relationships in the creatinine concentration range of 0.08~1 mmol/L with correlation coefficients all exceeding 0.978, and its sensitivity reached 283.3 μA/(mmol·cm²). Meanwhile, it possessed excellent anti-interference ability, mechanical stability and batch repeatability, and human sweat spiking experiments verified its feasibility for practical detection. Drawing on the skin microstructure of the Texas horned lizard, the biomimetic microfluidic chip was designed with an asymmetric microgroove array, and its structural parameters were optimized through COMSOL simulation (the side length of the biomimetic structure was 0.12 mm, the inter-structure spacing was 0.08 mm, and the spacing between the biomimetic structure and the channel wall was 0.06 mm), enabling the passive and spontaneous directional transport of sweat at a speed of 9.7 mm/s. The integrated capillary burst valve could effectively avoid sample cross-contamination, and the chip also had good flexibility and mechanical stability. This integrated "sensing-transport" platform breaks through the limitations of traditional technologies and achieves non-invasive, rapid and accurate detection of sweat creatinine, boasting broad application prospects in the fields of early warning of CKD, clinical auxiliary diagnosis, household health management and so on. The study also points out the existing problems of the current system, such as the difficulty in directly detecting low-concentration creatinine and the lack of wireless data transmission function. In the follow-up, the performance and clinical applicability of the platform will be further improved through material modification, multi-biomarker detection, intelligent system integration as well as large-sample clinical verification.

Speech Title:  Research and Application of Structured Light Measurement Technology Based on Polarization Imaging

Abstract: The high precision calibration of visual imaging and sensor is the core basic technology and fundamental guarantee of optical precision measurement.  With the application of optical measurement gradually developed from detection in a fixed environment to measurement in an uncontrollable environment (such as field measurement, etc.), the optical properties of the measurement environment and the surface of the object to be measured become more and more complex.  How to ensure the accuracy of the measurement system in the complex measurement environment has become an important direction of the development of structured light measurement system.  At present, most of the researches on 3D optical measurement use light intensity as information transmission channel.  Aiming at the problem of high precision measurement in complex environment, a calibration method of structured light system based on optimal polarization angle is proposed to improve the precision of system calibration.  A single image field calibration method for all parameters of structured light sensor based on cylindrical target is proposed, which solves the high precision field calibration of in-situ structured light optical measurement system and promotes the engineering application of structured light measurement.  A structured light coding technique based on polarization state is proposed to reduce the influence of camera defocus in structured light measurement system.  A fast measurement technique of polarization enhanced structured light fringes is proposed, which can reconstruct a wide range of reflectivity objects with only once exposure time.

Speech Title: Development of Intelligent Inspection Quadruped Robots

Abstract: Quadruped robots demonstrate significant advantages in certain fields due to their strong stability, high flexibility, broad adaptability, and outstanding load-carrying capacity. Over the past decade, substantial progress has been made in the field of quadruped robots, yet their potential remains not fully realized. To address complex environments in power plants, research is conducted on quadruped robot structural design, navigation and obstacle avoidance, as well as multi-dimensional perception technologies to achieve intelligent inspection with quadruped robots. Using bionic principles, the structure of the quadruped robot is designed and optimized, integrating both hardware and software. Reinforcement learning is employed for motion control, including gait planning, balance strategies, and recovery. Additionally, multi-sensor fusion technology, combining vision and lidar, is studied to enable autonomous navigation and obstacle avoidance for inspection tasks.

Speech Title: Research on the composite structure of metal-fiber-polymer heterogeneous materials

Abstract:Heterogeneous components offer an effective approach to weight reduction and efficiency enhancement for equipment by leveraging the complementary properties of metals, fibers, and polymers. However, the physical and chemical disparities between metals and polymers, such as mismatched coefficients of thermal expansion, pose technical challenges such as interfacial failure and poor structural stability for heterogeneous components. This project focuses on the interfacial bonding performance of metal-fiber-polymer heterogeneous components and systematically investigates the effects of sandblasting, chemical etching, and anodizing on the interfacial properties of 6061 aluminum alloy and polyamide (PA6). All three processes rely on the synergistic effects of "mechanical interlocking + interfacial diffusion" to improve interfacial performance, albeit through different pathways. In terms of mechanical interlocking, sandblasting forms rough peaks and valleys through physical impact, chemical etching constructs a porous network through chemical dissolution, and anodic oxidation generates a porous alumina film through electrochemical action, all providing mechanical anchoring sites. For interfacial diffusion strengthening, sandblasting promotes elemental interdiffusion and molecular interactions through surface cleaning, chemical etching through the exposure of active sites, and anodic oxidation through the formation of an oxide film.

Through SEM, EDS and three-dimensional morphology analysis, the synergistic effect of mechanical interlocking and elemental diffusion is revealed as the core mechanism of interface strengthening, and the ternary mapping model of "process parameters-surface characteristics-interface performance" and the quantitative relationship model between surface roughness parameters and interface strength are established. The model can be extended to the design and optimization of other metal-fiber-polymer composites.
