Piezoelectric Sensors And Ultrasonic Transducers - Types, Materials, Applications, New Developments, Industry Structure And Global Markets
LONDON, March 7, 2017 /PRNewswire/ -- Due to emergence of the Internet of Things (IoT) and automation in industrial processing and home applications, the demand for sensors and transducers has increased dramatically. A sensor is a device which detects change in physical parameters and converts it into signals which can be recorded or measured, e.g., vibration sensors which convert vibrations into voltage signals.

A transducer is a device which converts energy in primary form into corresponding energy signals in a different form. Important primary forms of energy include, for example, mechanical, electromagnetic, thermal, chemical and optical energy.
Sensors are used throughout agriculture, the power sector, healthcare, the automotive industry, telecommunications, instrumentation, and many other areas. To meet demand in these areas, various sensor-based products have been developed. Today, sensors are in use in gadgets for everyday living, as well as in airplanes, cellular telephones, radios and TVs, chemical and industrial plants, and more.
Due to the boom in wireless standard compliant devices based on WiFi, Zigbee and Bluetooth, home automation has become reality. Home automation relies heavily on sensors of various kinds, such as proximity sensors and motion sensors, liquid level sensors, smoke sensors, magnetic sensors, temperature sensors and light sensors, among others.
Piezoelectric sensors rely on the piezoelectric effect to measure a plethora of parameters such as pressure, strain, or force by converting them to voltages. Technically, piezoelectric sensors and transducers are one and the same. But piezoelectric sensors, more often than not, operate purely as sensors and do not apply voltage to generate an effect, as occurs in transducers. Key piezoelectric sensor products covered in this paper include the generic product families of accelerators, force sensors and pressure sensors.
Ultrasonic transducers include devices that produce ultrasonic signals (transmitters) which are received by other transducers (receivers) or devices that alternate between transmitting an ultrasonic signal and receiving a reflected signal (transmitter-receivers). The six generic families of transducers covered in this paper include flow sensors, proximity sensors, level sensors, acoustic sensors, medical imaging equipment and fluid property sensors.
The two non-military product groups covered – piezoelectric sensors and ultrasonic transducers – basically originate from the same material group, piezoelectric materials comprised of different grades of piezoelectric crystals, ceramics such as PZT, PVDF and ceramic/polymer composites.
STUDY GOAL AND OBJECTIVES
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 PE sensors and ultrasonic transducers based on piezoelectric ceramic, polymer and ceramic/polymer composite devices. This study provides data about the size and growth of markets, company profiles and industry trends for three categories of piezoelectric (PE) sensors and five generic sensor products. The report also highlights potential business opportunities.
A primary objective of this report is thorough coverage of underlying economic issues driving the growth in demand for PE sensors and ultrasonic transducers, as well as assessments of advanced piezoelectric devices that are being developed. Another important objective is to provide realistic market data and forecasts for PE sensors and ultrasonic transducers. 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 worldwide market development for PE sensors and ultrasonic transducers. 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 PE sensors and ultrasonic transducers in developed markets must contend with twin pressures – to innovate and, at the same time, to reduce costs. New applications for PE sensors and ultrasonic transducers have been proposed in recent years. This study condenses all of these business-related issues and opportunities.
REASONS FOR DOING THE STUDY
The PE sensors and ultrasonic transducers market is an attractive and still-growing multi-billion-dollar market characterized by very high production volumes of a diversified range PE sensors and ultrasonic transducers that must be both extremely reliable and low in cost. Growth in the PE sensors market continues to be driven by increasing demands in several segments including predictive maintenance and condition monitoring; testing and measurement of vibration in mechanical, electrical and manufacturing equipment and applications; vibration monitoring; high temperature applications; and harsh and explosive applications.
The diversified business of PE sensors and ultrasonic transducers is complex and fast moving, with manufacturers increasingly adopting a truly global view of the market. Around the world, consumers are demanding high quality along with an 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 PE sensors have a broad customer base, and new applications such as wireless sensors, miniaturized and tactile sensors, and structural health monitoring have now entered the mainstream and are showing significant sales volumes.
Ultrasonic sensors for medical imaging have a broad customer base, and new applications such as high-intensity focused ultrasound (HIFU) have now entered the mainstream and are showing significant sales volumes.
Structural health monitoring (SHM), tactile sensors (touch sensors), piezoelectric wafer active sensors (PWASs) for structural health monitoring of composite structures, and ultrasonic fingerprint sensors (PMUTs) that use a piezoelectric micro-machined ultrasonic transducer array integrated with complementary metal oxide semiconductor electronics sensor arrays are other areas showing significant growth.
With this background of new emerging technologies and applications, iRAP felt a need to conduct a detailed study and update technology developments and markets. This report identifies and evaluates new markets and new product developments which show potential growth for PE sensors and ultrasonic transducers.
