At 9 a.m. on May 30, 2025, Professor Xinge Yu from the School of Digital Medicine of City University of Hong Kong, invited by Professor Hui Huang, held a lecture on the theme of “Skin-integrated Electronics for Healthcare Monitoring and VR” at Room 304, Second Academic Park, Yanqihu Campus, University of Chinese Academy of Sciences (UCAS).

      Professor Xinge Yu graduated from the Department of Optical Engineering at the University of Electronic Science and Technology of China in 2005 with a Bachelor's degree in Engineering; Graduated from the University of Electronic Science and Technology of China in 2015 with a doctoral degree. Professor Xinge Yu is a member of the Hong Kong Academy of Youth Sciences, Vice Dean of the School of Digital Medicine at City University of Hong Kong, and Deputy Director of the Hong Kong Cardiovascular Health Engineering Research Center. In 2023, he was awarded the Hong Kong RGC Research Fellow, Outstanding Youth Science Foundation (Hong Kong and Macau), MIT Technology Review Innovation 35, IEEE Nanomedicine Inventor, MINE Young Scientist, and the Geneva International Invention Exhibition Gold Award. His research direction is the application of new flexible electronics in the field of biomedicine and intelligent tactile VR. Currently serving as the deputy editor in chief and editorial board member for multiple journals of Science Advances. Professor Xinge Yu has been recognized as one of the top 2% highly cited scholars at Stanford University. He has published over 200 papers in journals such as Nature, Nature Materials, Nature Biomedical Engineering, Nature Machine Intelligence, Nature Electronics, Nature Communications, and Science Advances, and has applied for/been granted over 50 US patents.

      Professor Xinge Yu first pointed out that the development of perception and interaction technologies based on flexible electronics and the human body is of great significance in many fields such as biomedicine, health, and sensing. Therefore, this is also a top priority in the research of flexible electronics technology. At present, the global research focus is almost entirely on the sensing technology of flexible electronics, while the research on information feedback of flexible electronics is relatively scarce. One of the main reasons is that flexible information feedback technology relies on actuators that are larger in size, weight, and power consumption compared to sensor devices. However, information feedback technology is an indispensable part of the interaction and perception of flexible electronics. For example, flexible electronics can collect changes in healthy physiological signals by wearing them on the human body. At the same time, by sampling and processing the collected health signals, the wearer's health status and potential diseases can be analyzed in a timely manner, and the user can be informed in a timely manner through feedback methods such as sound and pressure.

      Next, Professor Xinge Yu used monitoring heart rate as an example to talk about their team's development of a wearable flexible electronic device with extremely high moisture wicking efficiency. This device is lightweight, scalable, and significantly improves sweat wicking efficiency, solving the most critical problem faced by wearable biomedical devices. It can provide reliable and stable vital sign monitoring for up to a week without discomfort or signal distortion/interruption caused by sweating. In addition, Professor Xinge Yu’s team has also integrated wearable devices with the VR field, developing three multimodal tactile feedback interfaces with temperature, mechanical deformation, and electrical tactile stimulation. This wearable multimodal tactile feedback interface provides users with multi-dimensional high fidelity information, improves the immersion of virtual reality and augmented reality systems, and allows users to participate in the virtual world more immersively.

      At the end of the lecture, Professor Xinge Yu and everyone discussed profound issues such as how to achieve power supply for wearable devices, how to process and transmit large amounts of collected data, and what process should be adopted to prepare patterned electrodes. The lecture sparked lively discussions among teachers and classmates. Professor Xinge Yu’s lecture not only deepened the understanding of the interaction and perception of new flexible electronics among the attending teachers and students, but also provided valuable guidance for researchers.

     At 1:30 PM on May 26, 2025, Dr. Donghong Yu from the Department of Chemistry and Bioscience at Aalborg University, Denmark, delivered a lecture titled “Novel Carbazole-Based Self-Assembled Monolayers: Molecular Conformation and Its Impact on Organic Photovoltaic Performance” at Room 304, Teaching Building No. 2, Yanqi Lake Campus, University of Chinese Academy of Sciences. The lecture was hosted at the invitation of Professor Hui Huang from the School of Materials Science and Optoelectronic Technology.

     Dr. Donghong Yu received his Bachelor’s and Master’s degrees in Chemistry from Jilin University in 1991 and 1994, respectively. In 1997, he earned his Ph.D. from the State Key Laboratory of Polymer Chemistry and Physics at the Changchun Institute of Applied Chemistry, Chinese Academy of Sciences. From 1997 to 2006, he held positions as Assistant Professor, Special Research Fellow, Research Assistant Professor, and Assistant Professor at the State Key Laboratory of Polymer Chemistry and Physics (Changchun Institute of Applied Chemistry, CAS), the National Institute for Materials and Chemical Research (AIST, Japan), and the Departments of Mechanical Engineering and Chemistry & Bioscience at Aalborg University, Denmark. Since 2006, he has been a tenured Associate Professor in the Department of Chemistry and Bioscience at Aalborg University.

     Dr. Yu’s research interests span organic photovoltaic materials, polymer light-emitting diodes, molecularly imprinted polymers (for molecular recognition and biosensing), and inorganic-organic hybrid nanobiomaterials. He has led projects funded by the Danish Agency for Technology and Innovation, the Danish National Science Foundation, and the Danish Strategic Research Council, with a total research funding exceeding DKK 20 million. He has published 152 academic papers with over 4,030 citations. He has supervised 5 postdoctoral researchers, 12 Ph.D. students, and co-supervised 5 Ph.D. candidates. In 2009, he was honored with the Best Teacher Award at Aalborg University.

      In this lecture, Dr. Donghong Yu focused on a highly promising class of materials—carbazole-based self-assembled monolayers (SAMs)—and explored their application as hole transport layers (HTLs) in organic solar cells. Owing to their ultrathin film-forming capability and excellent interfacial tuning properties, these SAM materials have emerged as promising candidates for enhancing the architecture of photovoltaic devices, significantly enhancing both stability and efficiency. However, the specific influence of alkyl spacer chain length on the self-assembly behavior and device performance of SAMs remains insufficiently understood. To address this, Dr. Yu’s team designed and synthesized four bis(diazole)-substituted SAM materials with varying alkyl spacer lengths. A systematic evaluation was carried out to compare their molecular ordering, surface coverage, and impact on device performance.

      Structural analyses, including single-crystal X-ray diffraction, revealed that SAMs with shorter spacer chains exhibited stronger intermolecular interactions and denser packing. This favorable molecular conformation promoted the formation of more ordered monolayers and significantly influenced the molecular footprint and surface coverage on ITO electrodes. As a result, hole injection efficiency and interfacial charge transport were substantially improved. Thanks to these structural optimizations, the SAM-based devices ultimately achieved a power conversion efficiency exceeding 18%, positioning them at the forefront of current SAM-based organic photovoltaic technologies.

     This research provides new insights into the correlation between molecular structure and device performance in organic electronics. It also offers critical guidance for the molecular design of hole transport layers in next-generation, high-efficiency photovoltaic devices. At the conclusion of the lecture, Dr. Yu engaged in thorough discussions with faculty and students on topics such as material synthesis strategies and interfacial physics, thereby deepening the participants’ understanding of these advanced SAM-based materials.

      Professor Mingjie Liu first pointed out that polymer composite materials have been widely used in aviation, automotive, and green power generation fields due to their strong designability, excellent performance, and diverse functions. However, harsh environments such as lightweight, multifunctionality, high speed, and high temperature require higher performance and functionality of polymer composite materials. In the future composite system, it is necessary to establish an optimization model that links functional elements with macroscopic properties for multiphase composite, which is the key to improving material mechanical properties and expanding functionality. In addition, the polymer confinement effect in composite systems has a significant impact on the macroscopic performance control and optimization of materials, and it is necessary to understand the confinement effect from a molecular theoretical perspective.

      Next, Professor Mingjie Liu used biomimetic materials as an example to explain how to achieve the integration of structure and function of biomaterials through the design of multiphase confinement composites and multi-level ordered structures. Mingjie Liu's research group used confined space to regulate molecular movement, and realized the independent movement of orthogonal networks in confined space, thus preparing orthogonal network oil-water gel, which successfully simulated various functions of muscles; Inspired by the fluid force field, the team utilized a super spreading shear fluid to regulate the layer by layer orientation of nanosheets, ensuring that the materials could be quickly assembled to form highly ordered structures, thus preparing high-strength and tough layered nanocomposites, simulating the lightweight and impact resistance characteristics of shells.

From 1995 to 2015, fullerenes have been dominating the electron acceptor materials in the field of organic photovoltaics, so these 20 years are called the "fullerene era". However, fullerenes have weak absorption in the visible region, large energy loss, and device efficiency has touched the ceiling. In addition, fullerene spherical molecules are easy to aggregate, the morphological stability is poor, and the lifetime of the device is limited. In response to the above problems, Professor Zhan introduced the "star molecule" ITIC invented by his team, which is known as a "milestone" and "epoch-making", which created a high-performance novel receptor system of "fused ring electron acceptor", opened the "post-fullerene era" in the field, broke through the bottleneck of organic photovoltaics, achieved a leap in device efficiency, and brought unprecedented new opportunities for the development of the field.

After that, Professor Zhan vividly introduced the application and future development direction of fused ring electron acceptor materials in the fields of organic/perovskite/quantum dot solar cells, photohydrolysis, field-effect transistors, photodetectors, light-emitting diodes, two-photon absorption, photothermal/ photoacoustic/photodynamic therapy, etc. He encouraged the students to look at scientific research from a long-term and scientific perspective, to carry out self-revolution from time to time, to persevere, and to be down-to-earth. Finally, the professor had an exchange and discussion with the teachers and students on the spot, and received a warm response from the teachers and students on the spot.
