Ultrasonic Nano/Microfabrication, Handling, and Driving

Book excerpt: Ultrasonic nano/microfabrication, handling and driving is an emerging actuation technology, which utilizes ultrasonic vibration and the physical effects of ultrasonic vibration in fluids and solids to implement the fabrication, handling and driving of nano/micro scale objects. This book provides readers with the fundamentals, principles and characteristics of the ultrasonic devices for nano/micro fabrication, handling and driving, and design methods of the devices. • Introduces fundamental concepts and offers examples of ultrasonic nano fabrication, including ultrasonic nano rolling, cutting and coating methods. • Features a wealth of examples to illustrate the ultrasonic concentration and ultrasonic tweezers. • Explains the principles of ultrasonic driving of gas molecules and demonstrates their applications in high-performance gas sensor systems and metal-air flow batteries. • Teaches the principles of ultrasonic driving of microfluids and their applications in metal-air flow batteries and cooling of small solid heat sources. • Provides examples for the finite element method (FEM) modeling and computation of ultrasonic devices for nano/micro fabrication, handling and driving. • Summarizes the current and future trends in ultrasonic nano/microfabrication, handling, and driving. This book shares the advances, methods and applications of ultrasonic micro/nano fabrication techniques for entry-level and advanced readers working on nano/microfabrication, gas sensing, biological sensing, metal-air batteries, electronic component cooling, and other related areas.
