Market Dynamics

Global Surface Acoustic Wave Sensors Market Drivers:

Low Manufacturing Cost

A notable growth driver of the market under study is the cheap production cost of SAW devices and components. SAW components offer high-performance levels and unique qualities not seen solely in electrical components. Although BAW devices can handle higher frequencies and power levels than SAW components, SAW components are frequently less expensive. The SAW sensors can be used as disposable because of their tiny size and low cost, which are made possible by the lack of batteries and batch manufacturing. New conductive printing technologies have also made it possible to produce custom SAW devices more quickly and affordably, drawing additional end users into the industry under study. Businesses also utilize piezoelectric on-insulator (POI) substrates to create low-cost products. For instance, Qualcomm claims that its ultra saw RF Filter Technology outperforms rival filter technology while costing substantially less. A SAW filter on POI has a minor loss and is less expensive to produce than a SAW filter on bulk material. By utilizing low-cost production of custom SAW devices, more and more businesses are creating SAW devices for innovative sensing applications.

Global Surface Acoustic Wave Sensors Market Restraint:

Compatibility and Installation Issues

Surface acoustic wave (SAW) technology enables the integration of signal processing and sensor functionalities inside a single product. However, SAW sensors have had to deal with operational issues like poor stability and dependability, hampered their adoption rate. The restriction prevents the widespread adoption of these passive devices because all required fields of the SAW sensor require operation across a more expansive reading range. When the reply signal strength at the reader becomes insufficient for accurate recognition and identification, the SAW-based sensor system experiences its main restriction.

Global Surface Acoustic Wave Sensors Market Opportunities:

Wireless and Passive Nature of Sensors

The rise and popularity of SAW sensors across various applications are primarily attributed to their wireless and passive characteristics. These qualities also contribute to these sensors' small size and ease of use. As more and more industries adopt wireless technologies, the need for wireless applications has increased tremendously in recent years. They have acquired market share because of their cheap manufacturing costs, ability to be utilized as passive sensors, and ability to work wirelessly. One key contributing aspect to this is the development of RF communication.

SAW devices can be employed in sophisticated RF communication techniques to improve RF communication. SAW devices have been modulated in various ways, including orthogonal frequency coding and frequency-modulated continuous wave. Due to trends like the Internet of Things, the power transmission in the passive wireless SAW-based antenna sensor system has also received market traction (IoT). IoT is already impacting home automation and energy management systems because many IoT sensors are still installed in distant areas without easy access to power outlets, forcing them to operate on batteries.



Segmental Analysis

The global surface acoustic wave sensors market is segmented by sensing type and end-user industries.

Based on sensing type, the global surface acoustic wave sensors market is bifurcated into pressure sensors, torque sensors, temperature sensors, humidity sensors, chemical sensors, and other sensors. 

The pressure sensors segment is the highest contributor to the market and is estimated to grow at a CAGR of 9.26% during the forecast period. A pressure sensor is a device made up of a sensitive element that uses various working principles to identify the pressure applied to the sensor and other components that turn this information into an output signal. Due to the expanding applications across numerous industries, including oil and gas, aerospace, automotive, healthcare, consumer goods, and industrial, these sensors have experienced tremendous expansion over the years.

The market is anticipated to be driven by the increasing use of surface acoustic wave pressure sensors for permanent sound monitoring systems in the oil and gas industry, which have supplanted quartz crystals and fiber optics as the primary downhole pressure gauge materials. A tire pressure monitoring system for cars can use these pressure sensors. This type of sensor benefits from a SAW's ability to operate wirelessly without a battery. The Tire Pressure Monitoring System (TMPS) can be stimulated by signals of various frequencies using a one-port SAW resonator and antenna, and it can then receive a response from the SAW.

Humidity sensors come in various shapes and capacities and are increasingly used in mobile devices. Other humidity sensors are integrated into larger embedded systems (such as air quality monitoring systems). SAW humidity sensors are also used in the manufacturing, HVAC, automotive, agriculture, meteorology, and agricultural industries. When choosing a humidity sensor, significant factors are mass loading, acoustoelectric effects, and viscoelastic effects. SAW sensors with an elastic hygroscopic polymer covering are increasingly popular for measuring humidity. Another material that is quickly becoming popular for the sensitive layer of the SAW humidity sensor is graphene oxide. These humidity sensors have a quick response time of around 8.3 seconds and a quick recovery time of about 4.8 seconds. They can offer good reversibility, outstanding short-term repeatability, and stability. Some of their applications include integrated relative humidity (RH) detection devices with a small form factor based on SAW sensors.

Based on end-user industries, the global surface acoustic wave sensors market is bifurcated into automotive, aerospace and defense, consumer electronics, healthcare, industrial, and other end-user industries. 

The consumer electronics segment owns the highest market and is estimated to grow at a CAGR of 10.37% during the forecast period. Consumer electronics has historically been a significant investor in and user of SAW sensors, which has considerably impacted the advancement of SAW sensors and devices. In many consumer and communication applications, RF filters have significantly benefited from using SAW sensors. SAW devices, for instance, have a relatively straightforward design. The cost of sensor materials has decreased over the past three decades due to the widespread use of SAW filters in the smartphone sector. Acoustic wave filters, commonly SAW devices, are produced in more than one billion units annually, primarily for cell phones. The SAW devices serve as band-pass filters in the transceiver circuitry's RF and intermediate-frequency parts. Most touchscreen input on smartphones and personal digital assistants uses this technology.

Applications that use the extraordinary sensitivity of SAW devices to surface perturbation include engine coolant temperature control, outside air temperature management, cylinder heat temperature management, and dangerous chemical vapor sensing. If these are coated with a substance that selectively adsorbs molecules from the air, SAW devices can also monitor/sense gases and organic solvents. Industrial robotics' expanding use will also present market vendors with prospects for future expansion. The advantages of SAW sensors have recently attracted the attention of the renewable energy industries. Measurements of pressure, torque, and temperature are essential in the never-ending quest for adequate renewable energy and industrial applications.
