Course Description: Piezoelectric ultrasound transducers are a crucial component in mostultrasound systems, with applications including biomedical imaging and therapy, nondestructive evaluation and underwater sonar. The content of this course covers topics providing a foundation of understanding about the fundamentals of ultrasound transducers and an informed appreciation of more advanced subjects in the state of the art. The course is divided into four sections. Ceramic, single crystal and polymer piezoelectric materials are introduced in the first section, along with mathematical descriptions for them and their behavior and an explanation of the underlying physics. New materials such as ternary single crystals are compared with those in use since the 1950s and topics of increasing interest including lead free materials are covered. In the second section, the operating principles of transducers are described with particularly reference to wave propagation. Electrical impedance spectroscopy is introduced as a key technique for transducer characterisation, along with ultrasound transmission and reception techniques. The different types of one-dimensional model are presented, and this leads to a description of external electrical circuitry, including the latest integrated electronic implementations. The third section covers waves, fields and signals. The field of a transducer is introduced through the concept of its physical aperture, different wave modes, and reciprocity. Huygen’s principle is outlined and techniques to predict ultrasonic field characteristics are presented. Advanced work on shear waves in tissue is introduced. Electronic arrays are outlined and finite element analysis is used to provide examples of transmitted fields. More advanced topics in long range transmission and thin film devices are covered. The importance of signal analysis in the time and frequency domains is emphasised, and this is illustrated with reference to time reversal techniques. An example dual-element transducer design is used as a common thread to illustrate important results throughout the course and practical demonstrations will be provided on materials characterisation and analysis with electrical impedance spectroscopy, one-dimensional transducer design software, and pulse-echo transducer operation.

Short Course 4A (8:00 A.M. - 12:00 Noon, Monday, October 11, 2010):

Course Title:  Microacoustic Devices as Chemical Sensors

Gerhard Fischerauer, University of Bayreuth, Germany.

Course Description:   Microacoustic chemical sensors based, for instance, on quartz crystal microbalances (QCM) or surface acoustic wave (SAW) devices have been popular in laboratories around the world for almost 30 years. They have also met with some commercial success, and one of the underlying effects, viz., mass loading, is routinely used in thin-film technology to monitor film growth during deposition. This shourt course aims at introducing the principles of such sensors and typical issues likely to crop up during their application. The focus is on physical and functional aspects with an emphasis on transduction mechanisms and terminal characteristics. For this reason, the course might also appeal to those interested in microacoustic sensors in general. The course will be broken down into three sections. The first section covers the operating priciples of microacoustic devices, their design and fabrication. Devices discussed include QCMs and resonators, delay lines, and ID tags based on Rayleigh waves, Lamb waves, Love waves, shear-horizontal waves, etc. In the second section, possible interactions of the microacoustic waves with their environment will be investigated. These interactions are of a primarily physical nature, examples being mass loading, changes in electrical conductivity, and changes in elastic properties. A chemical sensor is obtained by coating the devices with layers which selectively incorporate the chemical species of interest. The details of the transduction process from analyte concentration to acoustic wave properties to device terminal characteristics will be described. The final section is devoted to practical issues such as instrumentation (vector network analyzer, oscillator, frequency counter, interrogation of RFID tags), suitable signal characteristics, and disturbances of the measurement process. Typical non-idealities and sources of misinterpretation of measured data are identified. Finally, we will discuss methods to suppress the influence of temperature and to speed up the effective sensor response by signal processing approaches.

Gerhard Fischerauer was born in Munich, Germany, in 1963. He received the Dipl.-Ing.and the Dr.-Ing. degrees from the Technical University of Munich, Germany, in 1989 and 1996, respectively.

Short Course 5B (1:00 P.M. - 5:00 P.M., Monday, October 11, 2010):

Course Title:  Applications of High Frequency Ultrasonics in Microfluidics

James Friend, Monash University, Melbourne, Australia.

Course Description:  The transmission of acoustic waves through materials and across interfacial-discontinuities is a centuries old area of research. A rather curious application of ultrasonic acoustic radiation--actuation of fluids and particles within them--has renewed interest in this area and exposed phenomena that are not explained by previous theories once viewed as canon. During the talk applications of these phenomena will be proffered, including fingernail-sized microdevices to atomize sessile droplets for drug encapsulation, pulmonary drug delivery and nanoparticle formulation; devices for droplet jetting and manipulation; a device for fluid pumping and particle segregation in closed microfludics structures; and a device to enable micro and nanoparticle concentration and separation in a sessile droplet in a matter of seconds. These technologies indicate the potential for ultrasonics to deliver on the many idyllic promises of microfluidics. Along the way, the underlying physical phenomena will be explored and explained, and the potential future of this area will bring the course to a close. This course will offer an overview of ultrasonics at small scales, including fabrication, piezoelectrics and fluid physics; proper analysis of ultrasonic &eld propagation in viscous fluids at small scales incorporating nonlinear phenomena with a review of classical terminology; and the many applications of the phenomena from fluid pumping and jetting to particle separation and organic chemistry enhancement.
