At 10:30 on September 9, 2024, Professor Chai Yang from the Hong Kong Polytechnic University was invited by Professor Huang Hui to give a lecture on " Bioinspired in-sensor computing for artificial vision" in the University of Chinese Academy of Sciences. The lecture was held in Room 101 on the first floor of the classroom.

      The demand for accurate perception of the physical world leads to a dramatic increase in sensory nodes. However, the transmission of massive and unstructured sensory data from sensors to computing units poses great challenges in terms of power-efficiency, transmission bandwidth, data storage, time latency, and security, To efficiently process massive sensory data, it is crucial to achieve data compression and structuring at the sensory terminals. In-sensor computing integrates perception, memory, and processing functions within sensors, enabling sensory terminals to perform data compression and data structuring.

      In this presentation, Professor Chai Yang describes the team's efforts in biosensor computing for artificial vision. Discuss the framework of in-sensor computing and show some vision sensors for different scenarios, including vision adaptation, motion perception, and event-driven vision sensors for pulsed neural networks. Professor Chai Yang exchanged and discussed with the on-site teachers and students, and got a warm response from the on-site teachers and students.

      Prof. Yang Chai is the Associate Dean of the Faculty of Science, the Director of Joint Research Center of Microelectronics of the Hong Kong Polytechnic University, the Vice President of the Phvsical Society of Hong Kong, a member of The Hong Kong Young Academy of Sciences, an IEEE Distinguished Lecturer since 2016, the Vice Chair of lEEE EDS region 10, the chair of IEEE EDS Nanotechnology Committee, and was the Chair of IEEE ED/SSC Hong Kong chapter (2017-2019). His current research interest mainly focuses on emerging electronic devices.
