Increasing investments in the magnetic sensor ecosystem are driving market growth
The rising adoption of magnetic sensors in advanced applications, such as autonomous cars, is expected to spur the growth of the magnetic market across the globe. Magnetic sensors used in these systems are highly efficient, accurate, reliable, robust, and simple in design. Magnetic sensor manufacturers increasingly invest in different magnetic sensing technologies, such as 3D sensing, tunnel magnetoresistance (TMR), and giant magnetoresistance (GMR), to enhance their domain expertise and strengthen their market position. Moreover, these players are also expanding their magnetic sensor product portfolios by introducing newer products to cater to the needs of various end-use markets.
For instance, in February 2020, Allegro MicroSystems, LLC (US) introduced ATS19580, a fully-integrated, back-biased GMR transmission speed and direction sensor for automotive applications. The sensor helps reduce system size, complexity, and costs, improving fuel economy. This factor drives the market CAGR.
Hybrid and electric vehicles are also gaining traction as they are more digitally connected than conventional vehicles. Also, they reduce the consumption of fossil fuels, such as petrol and diesel, reduce warming and ecological damage, and offer superior fuel efficiency. Additionally, due to COVID-19, the automotive industry has been facing a slowdown in demand for hybrid, electric, and autonomous vehicles. However, the demand for hybrid, electric, and autonomous cars is likely higher than any other vehicle type post-COVID-19.
The surge in demand for these cars can be attributed to changing lifestyles, governments encouraging the adoption of green vehicles to reduce CO2 emissions, and the advent of advanced technologies.
One of the major advantages of using electric cars is that these cars are pollution free. In addition, several giant car manufacturers, such as GM (US), Ford (US), and Renault (France), are expanding their hybrid and electric car businesses. Power electronics is a key technology for hybrids and accounts for ~20% of the total cost of hybrid vehicles. This creates high growth in the Magnetic Field Sensor market revenue.
The increasing integration of magnetic field sensors in automotive applications, particularly for advanced driver-assistance systems, appears to drive innovation and demand within the global market.
