傳感器端計算的研究發表《自然納米技術》上（只有英文版本）

(只有英文版本)Prof. Yang CHAI, a member of RI-IWEAR, collaborated with the researchers at Yonsei University in Korea and published an article entitled “Optoelectronic graded neurons for bioinspired in-sensor motion perception” in Nature Nanotechnology.    The motion perception by conventional machine vision usually occupies abundant computation resources, which greatly restricts its application at edge terminals. To perceive the dynamic motion at sensory terminals, it demands the hardware that can conduct visual processing in a more efficient way. Flying insects can agilely detect the motion with a tiny visual system (~800 photoreceptors and 10^5 neurons in the brain), which inspires us to emulate the characteristics with hardware devices for in-sensor motion perception.   One of the reasons for the agile visual system of flying insect is its graded neural structure, which exhibits much higher information transmission rate (>1000 bit/s) than that of spiking neuron (~300 bit/s) and allows to fuse spatiotemporal information at sensory terminals. Prof. Chai’s team adopted MoS2 phototransistor to emulate the non-spiking graded neurons of insect vision systems. The charge dynamics of the shallow trapping centres in MoS2 phototransistors mimic the characteristics of graded neurons, exhibiting multilevel response and volatile feature.   The optoelectronic graded neuron array can directly perceive different types of motion. The bioinspired sensor array can detect trajectories in the visual field with very economical hardware devices, allowing the efficient perception of the direction of the moving objects. By modulating the charge dynamics of the shallow trapping centres in MoS2 phototransistor, the bioinspired sensor array can recognize the motion with a temporal resolution ranging from 10^1 to 10^6 ms.   The bioinspired sensors have potential applications in robotics and artificial intelligence. For example, it could be used to develop more efficient and robots with better motion perception abilities by detecting and responding to the moving objects in the surrounding environment.

發表在《生物活性材料》上的人造纖毛新研究（只有英文版本）

（只有英文版本）Preservation of growth factor sensitivity and bioactivity (e.g., bone morphogenetic protein-2 (BMP-2)) postimmobilization to tissue engineering scaffolds remains a great challenge. Dr Xin ZHAO, member of RI-IWEAR, collaborated with Prof. Zijian ZHENG, Associate Director of RI-IWEAR developed a stable and soft surface modification strategy to address this issue. BMP-2 (a model growth factor) is covalently immobilized onto homogeneous poly (glycidyl methacrylate) (PGMA) polymer brushes which are grafted onto substrate surfaces (Au, quartz glass, silica wafer, or common biomaterials) via surface-initiated atom transfer radical polymerization. This surface modification method multiplies the functionalized interfacial area; it is simple, fast, gentle, and has little effect on the loaded protein owing to the cilia motility. The immobilized BMP-2 (i-BMP-2) on the surface of homogeneous PGMA polymer brushes exhibits excellent bioactivity (⁓87% bioactivity of free BMP-2 in vitro and 20%–50% higher than scaffolds with free BMP-2 in vivo), with conformation and secondary structure well-preserved after covalent immobilization and ethanol sterilization. Moreover, the osteogenic activity of i-BMP-2 on the nanoline pattern (PGMA-poly (N-isopropylacrylamide)) shows ⁓110% bioactivity of free BMP-2. This is superior compared to conventional protein covalent immobilization strategies in terms of both bioactivity preservation and therapeutic efficacy. PGMA polymer brushes can be used to modify surfaces of different tissueengineered scaffolds, which facilitates in situ immobilization of growth factors, and accelerates repair of a wide range of tissue types. This research was published in Bioactive Materials, Volume 24, June 2023.
