Traditional applications of piezoelectric devices are ultrasonic medical imaging, ultrasonic non-destructive testing, ultrasonic sensors, vehicle knock sensors, acoustic devices such as speakers, beepers, ceramic resonators, ultrasonic welding, ultrasonic cleaning, vibration cancellation, and sonars for military and civil use. Some new and growing applications include actuators, ultrasonic motors, sensor arrays for structural health monitoring, oil and gas field sensors, transformers and micro energy harvesting devices which are an alternative to batteries in microwatt devices. Other new applications include high resolution ultrasonic medical imaging, computer disk drives, and accelerometers in mobile phones and notebooks.
The piezoelectric device sector is actually not a single sector, but rather comprises a number of sectors with distinctly different characteristics. The sectors of most significance are:
•the piezoelectric device sector, with high production volume, consisting of generic piezoelectric devices such as actuators, motors, sensors, accelerators, transducers for ultrasonic medical imaging and non-destructive testing acoustic devices, Lengevin actuators for ultrasonic welding and cleaning, ceramic resonators, and miscellaneous types of devices designed for special applications such as transformers, vibration and noise cancellation in structures limited to different grades of piezoelectric crystals, ceramics such as PZT, PVDF and composites;
•sonars for military and civil use; and.
•niche applications such as energy harvesting, where piezoelectric devices such as generators offer a unique competitive advantage.
Piezo devices also include ultrasonic motors (USMs), which offer a high potential for miniaturization. These actuators produce no magnetic field since the excitation is quasi-electrostatic. Through their specific advantages compared to conventional electromagnetic motors, USMs fill a gap in certain actuator applications. A key advantage of USMs over electromagnetic motors is their compactness, i.e. their high stall torque-mass ratio and high torque at low rotational speed, often making speed-reducing gears superfluous. Additionally, with no voltage applied, an inherent holding torque is present due to the frictional driving mechanism. It is also worthwhile to mention that their compactness and the high frequency electrical excitation make quick responses possible.
STUDY GOAL AND OBJECTIVES
This study focuses on key piezoelectric devices and provides data about the size and growth of the piezoelectric devices markets, company profiles and industry trends. The goal of this report is to provide a detailed and comprehensive multi-client study of the markets in North America, Europe, Japan, China, Korea and the rest of the world (ROW) for piezoelectric ceramic, polymer and ceramic/polymer composite devices, as well as potential business opportunities in the future.
A primary objective of this report is thorough coverage of underlying economic issues driving the piezoelectric ceramic and polymer devices business, as well as assessments of new, advanced piezoelectric devices that are being developed. Another important objective is to provide realistic market data and forecasts for piezoelectric devices. This study provides the most thorough and up-to-date assessment that can be found anywhere on the subject. The study also provides extensive quantification of the many important facets of market development in piezoelectric devices throughout the world. This, in turn, contributes to a determination of the kinds of strategic responses companies may adopt in order to compete in these dynamic markets.
Users of piezoelectric devices in developed markets must contend with twin pressures – to innovate and, at the same time, to reduce costs. New applications for piezoelectric devices have been proposed in recent years. This study condenses all of these business-related issues and opportunities.
REASONS FOR DOING THE STUDY
The piezoelectric devices market is a diversified but attractive and still-growing multi-billion dollar market characterized by very high production volumes of a diversified range of piezoelectric devices that must be both extremely reliable and low in cost. Growth in the piezoelectric devices market continues to be driven by increasing demands in camera phones for autofocus mechanisms, piezo transformers, energy harvesting devices, data storage, semiconductors, microelectronics production, precision mechanics, life science and medical technology, optics, photonics, nanometrology, robots, toys, HVAC control systems, hand-held consumer electronic devices, automotive sensors, ultrasonic transducers for medical imaging and non-destructive testing and vibration related applications, structural health monitoring, ultrasonic welding and cleaning, ceramic resonators for mobile phones and devices used for information and communication technologies. Since sonars for military and civil uses and other applications constitute an established market, we have included this segment in this report.
The diversified piezoelectric ceramic device business is complex and fast moving, with manufacturers increasingly adopting a truly global view of the market. Around the world, consumers are demanding high power density as well as extremely long cycle life. In this challenging market, manufacturers have attempted to achieve growth through company mergers and acquisitions and by implementing global strategies. Traditional piezoelectric devices have a broad customer base, and new applications such as ceramic resonators in mobile phones, transformers in notebooks, and energy harvesting are new areas that have now entered the mainstream and are showing significant sales volumes.
The global market for traditional piezoelectric devices is quite mature in applications. However, the global market for new piezoelectric devices will see even a much higher growth rate in next five years.
With this background of new emerging technologies, applications and markets, iRAP felt a need to conduct a detailed study and update technology developments and markets. The report identifies and evaluates piezoelectric ceramic, polymer and ceramic/polymer composite devices and technologies which show potential growth.
