特邀專家：Prof. Joshua En-Yuan Lee (City University of Hong Kong)
主講人簡介(Biography)：Dr Joshua Lee received the B.A. (Hons) and M. Eng. (Distinction) degrees in 2005, and the Ph.D. degree in 2009, all from the University of Cambridge, U.K. He joined the faculty of the Department of Electronic Engineering, City University of Hong Kong in June 2009, where is currently an Associate Professor and is affiliated with the State Key Laboratory of Millimetre Waves. He is also the Program Leader for Postgraduate Studies; in which capacity he is responsible for graduate affairs and admissions. In 2017, he was a visiting professor at University Grenoble Alpes in France. His research interests include the design, analysis, and characterization of Microelectromechanical Systems (MEMS) for sensing and frequency control applications. He has authored over 130 articles on the topic of MEMS. Dr Lee is a Senior Member of the IEEE. He has served on the Technical Program Committees of various conferences including ISQED, IFCS, and Transducers.
內容簡介(Content)：While it is obvious that technology has changed our societies even within the short span of the last decade, one ought to notice that much of it has to do with sensors. Sensors have exploded on the scene. But a historical look at technology development will reveal the long path for sensor technology development from research to product. For example, inertial sensors were proposed in the 1980s but only became big business in the 2000s. There is still much work being done on sensors. This talk will touch on developments on two different types of sensors. The first example is a magnetic field sensor targeting electronic compass applications where the goal is to realize highly integrated inertial measurement units where the different sensing modules are all made from mechanical devices. In this part of the talk, I will show the process of shifting from one technology to another and the reasons behind the shift. If the first example aims to show the commercial impact of micromechanical devices, then the second example aims to show their impact on basic research. The second example involves developments in sensors that can work in the liquid-phase towards the goal of weighing single cells. In this part of the talk, I will touch upon some of the technical issues involved in developing such devices and what is the current status.
