This month, two research teams at the University of Tokyo in Japan made a breakthrough by developing a thin-film wireless communication system. This innovative technology enables electronic devices to communicate simply by placing them on the film. A key component of this system is the MEMS-based switch film, which plays a crucial role in enabling seamless and efficient data transmission.
MEMS, or Micro-Electro-Mechanical Systems, are known for their compact size, ability to integrate multiple functions, and cost-effective mass production. These features make MEMS highly promising for various applications, especially in fluid dynamics, where they offer unique advantages. China has also made significant progress in MEMS research, with several notable achievements.
Professor Ding Jiexiong from the School of Mechanical and Electronic Engineering at Chengdu University of Electronic Science and Technology is one of the pioneers in this field. He has developed a method for ultrasonic suspension particle separation based on multimode resonance in MEMS. His work focuses on how ultrasonic energy can be used to manipulate suspended particles in fluids, offering a new approach to particle separation.
In mixed fluid systems, suspended particles often pose the main challenge. Ultrasonic waves generate an average force on these particles, allowing precise control over their movement. This makes it possible to separate particles efficiently. However, traditional separation techniques face limitations when applied to microscale systems. Fortunately, ultrasonic devices are well-suited for integration with MEMS, making them a powerful tool in microfluidic applications.
Professor Ding’s research explores the use of cavity multimode resonance combined with laminar flow to achieve more effective particle separation. His work includes detailed studies on the two-dimensional standing wave sound field, resonant cavity structure modeling, and the design and optimization of microfluidic channels and inlet-outlet structures. Through extensive experimental research, he has significantly advanced the development of micro-separation devices and gained deep insights into the factors that influence separation efficiency.
The potential of ultrasonic particle separation technology is immense, particularly in biomedical and environmental fields. As its impact on society continues to grow, the economic and social value of such innovations becomes increasingly significant. With ongoing research and development, this technology could revolutionize many industries in the near future.
