Piezoelectricity is a property displayed by some materials wherein the material generates an electric field when a force is applied. On the other hand, when an electric field is applied across the material, it shows deformation in its dimensions. In other words, these materials convert mechanical energy to electrical energy and vice versa. Due to this property, they are commonly referred to as transducers. These materials use piezoelectricity to measure changes in speed, stress, strain, heat, or force by converting the differential in energy into electrical charge. Based on this effect, these materials find application in producing and detecting sound and frequency, ignition devices, SONAR, and pressure & displacement measurement systems.
Nowadays, piezoelectric devices employ a wide variety of materials such as quartz crystal, Rochelle salt, ceramics, polymers, macro-fiber composites, ferroelectrets, and flexoelectric materials. The selection of material for different applications is based on properties such as consistency, stability, high input-to-output ratio, malleability, and heat & humidity resistance. Primarily quartz crystals were employed in piezoelectric devices. Still, its inability to react at low voltages and function at temperatures above 300ᵒ C obligated its replacement by modern materials such as piezoceramics and piezo composites.
Increasing Demand from Healthcare Industry to Balance the Impact of COVID-19
Covid-19 has severely affected the value chain of the piezoelectric materials manufacturers. The raw material supply was involved as the mining industry faced lockdown restrictions announced by key countries, including China, India, and Brazil. Furthermore, crucial end-use industries such as the electronics and automotive sectors faced restricted operations and shutdowns, which critically impacted the demand for these materials. However, COVID-19 presented a spike in demand for equipment such as pyrometers, oximeters, automated ventilators, and electronic thermometers. These devices utilize piezo materials to convert one form of energy to another and thus demand these materials during a crisis.
Furthermore, companies operating in the market have modified their production plants to accommodate the growing demand from the healthcare industry. They also have developed novel products in combination with healthcare electronics manufacturers to study coronavirus and its traits. For instance, PI Ceramics developed piezoceramics that enable precise liquid handling for in-vitro diagnostics for early diagnosis and disease detection.

Development of Lead-Free Piezoceramics to Stimulate Development
While lead zirconate titanate (PZT) is the largest used piezoceramic material, its usage is constrained due to the presence of lead in the compound, which subjects PZT to the regulations such as Restrictions of Hazardous Substances (RoHS) Directive 2002/95/EC adopted by EU. Therefore, the development of lead-free piezoceramics is a large, ongoing research area. Lead-free piezoceramics consist of three main compositional families, titanate-based ceramics, alkaline niobate perovskite-based ceramics, and bismuth perovskite-based ceramics. Furthermore, polymers showing piezoelectric properties, including polyvinylidene fluoride (PVDF) and polysulfone, are under study to provide compliant piezoelectric materials. As lead is considered to be poisonous to humans, such research on the replacement of lead-based ceramics is expected to gain momentum in the near future further and alter the course of the market towards further growth.
Increasing Automation in End-Use Industries to Boost Market Growth
End-use industries such as automotive and electronic manufacturing have pushed for automation in their manufacturing lines. This push has increased the demand for devices such as sensors, transducers, actuators, and motors to run the production line smoothly. As these devices use properties endowed by the piezoelectric materials to measure various quantities such as acceleration, pressure, strain, and acoustic intensity, the demand for such materials is projected to expand considerably with the increasing dependence of industries on automation.
Increasing Spending on Aerospace & Defense to Spur Demand
In recent years, governments of countries such as India, China, the U.S., Israel, and Japan have significantly increased their budget on defense activities. These governments invest heavily in building missile guidance systems, drones, and radars to strengthen their armed forces’ capabilities. Furthermore, an increase in space exploration activities has led to an increase in the usage of devices such as sensors, acoustic devices, and SONARs to study space objects and related environments. These devices require special piezoelectric materials that can detect the slightest change in their range, sustain in harsh conditions, and provide accurate & consistent results. With private space agencies such as SpaceX taking a jump into providing space exploration services, the demand for such materials is further expected to inflate the global piezoelectric materials market growth during the forecast period.
Lack of Differentiation between Signals and Noise to Diminish the Adoption of Piezoelectric Materials
While piezo materials find extensive application in sensing and energy conversion devices, common materials such as PZT and natural piezo crystals are unable to differentiate between actual signals and noise present in the system, which may result in an inaccurate outcome, affecting the performance of the device wherein the piezoelectric material is employed. Furthermore, when subjected to harsh environments such as high temperature and heavy stress, the consistency of results provided by the material is severely affected, further restricting its adoption for application in such conditions.
Piezoceramics Material Segment to Hold Dominant Share in the Market
Based on material, the market is classified into piezoceramics, piezopolymers, piezo composites, and others. Piezoceramics are further bifurcated into lead zirconate titanate (PZT) and lead-free ceramics. Piezoceramics are expected to hold the dominant share in the market on account of the large consumption of PZT for the manufacturing of transducers and actuators as the performance of PZT can be easily modified based on the usage of doping materials. While doping with niobium produces soft-PZT, which increases its response capabilities, doping with iron forms hard-PZT, which shows more negligible hysteresis in the piezoelectric response. Such adaptability of piezoceramic materials has resulted in its large-scale consumption from the electronics and automotive industry.
On the other hand, piezo composites are swiftly gaining market share as they are preferable for application in ultrasonic equipment, non-destructive testing, and underwater acoustics. Composites offer smaller acoustic impedance than piezoceramics, are more plastic, and can better adapt to mechanical loads. They possess better piezoelectric sensitivity and electromechanical activity and thus are considered to be effective alternatives to piezoceramics.
Sensors Segment to Grow with Highest CAGR during the Forecast Period
In terms of application, the market is segmented into actuators, motors, transducers, sensors, SONAR, generators & transformers, acoustic devices, resonators, and others. The sensors segment is expected to grow at a considerable CAGR owing to its application in various fields, including automatic vehicles, manufacturing lines, and consumer electronics. Sensors detect the change in energy and convert the difference into electrical signals, which are used to make necessary changes in the system. For instance, the TV's remote control has a pressure sensor, which detects the pressure on a button and converts it into an electrical signal that activates the IR blaster present on the remote. Inside the television unit, the IR sensor detects the change in energy and converts it into a digital signal, provisioning control of the unit.
On the other hand, an actuator converts electrical signals sent by the system or user into mechanical energy to control the designated part to perform a certain action in the manufacturing line. Thus, the actuators segment is expected to account for the largest piezoelectric materials market share in the global market with its application ranging from precision control of industrial machining tools, vehicle acceleration & braking systems, and robotic arms used in various end-use industries.
