Analysts expect the wireless pressure sensor market to register a compound annual growth rate (CAGR) of 20.8% from 2019 to 2024, driven by advancements in microelectromechanical systems (MEMS) technology, growing demand from automotive and medical device industries, rapid adoption in connected devices, increasing adoption of pressure sensors in consumer goods and wearables, and stringent government regulations.

The wireless sensors market is growing rapidly as many sensor manufacturers focus on technological research and improvements.

The use of MEMS wireless pressure sensors in industrial control applications and processes, heating, ventilation, and air conditioning (HVAC) applications, and level measurement is driving market growth. Government regulations or laws to ensure passenger safety in automobiles are also expected to be a major growth driver.

Key challenges for wireless pressure sensors include a highly fragmented market, scarcity of open bandwidth, low reliability, frequency hopping challenge, and constantly evolving standards.

However, the demand for high-performance, cost-efficient, and reliable sensors has increased, leading to higher spending in research and development (R&D) by market vendors. These technological advancements in nanotechnology and micro-technology are expected to propel market growth for several years.

Key market trends

The automotive segment should grow at a steady rate as technology progresses and automation advances. Motor vehicles have been an important end-user segment for legacy pressure sensors as high quality and absolute reliability are preferred in automotive manufacturing.

To achieve the optimum condition regarding performance and system cost, pressure sensors have been a prime choice in many critical applications. However, with emerging applications, such as vehicle dynamics control, offline navigation, external airbag deployments, and tire pressure monitoring, wireless pressure sensors are becoming increasingly popular.

With futuristic innovations, such as electric and self-driving cars, automotive sector demand for wireless pressure sensors is assumed to grow quickly. Powertrain applications represent more than 50% of the business, followed by safety, with tire pressure management systems (TPMS) being the largest single automotive application (federal rules mandate TPMS on motor vehicles). Driven by carbon dioxide emission reduction and automation, wireless pressure sensors will increasingly be adopted and used in the future.

Strong market share

North America is expected to hold a dominant position in the global wireless sensors market. The U.S. is primary with companies such as Rockwell Automation and Texas Instruments. Technological proliferation and advancements in nanotechnology and micro-technology are expected to propel the market growth in North America throughout the forecast period.

Moreover, the growing demand for wireless sensors in the defense sector is anticipated to fuel market growth. In 2019, the U.S. Department of Defense estimated a budget of $13.7 billion for investing in technological development. These investments are expected to increase s technology advances, which will further boost the wireless sensors market.

Competitive landscape

The highly competitive wireless pressure sensors market consists of several major players. The numerous applications offer manufacturers increased potential to adopt collaborative initiatives such as product innovations to increase their market share and increase their profitability. Market concentration is low with players striving to expand their reach.
