The global radiation-hardened sensors market will expand more than 4% yearly until 2035, according to a new analysis by Fact.MR.
The company has analyzed these sensors by type, across temperature sensors, pressure sensors and more, as well as by material and region. The inertial sensors (accelerometers, gyroscopes, Imus) is projected to grow at a faster rate of 6%, while temperature sensors will grow at 5.7%. The US is expected to see growth through the period annually of 6.5% followed by Japan at 6.3% and India at 6.2%.
With these growth rates in mind, Fact.MR said the global radiation-hardened sensors market is expected to reach $2.7 billion by 2035, up from $1.7 billion in 2025.
National security decisions by countries will affect the growth in aerospace and defense programs that rely on radiation sensors. Space exploration and more autonomous platforms will affect the growth. MEMS are now focused on greater reliability in orbital and tactical environments for inertial sensors and imaging. Wide-bandgap semiconductors have also improved sensors tolerance to ionizing radiation.
Satellites will make up the biggest radiation-hardened sensors market, now at nearly 30% of the entire market.
The biggest players in the radiation-hardened sensor market are Texas Instruments, Microchip, Analog Devices, Honeywell International, Infineon and STMicroelectronics, according to Fact.MR. In 2025, TI demonstrated a new family of 200 V radiation-hardened GaN FET gate drivers to be used in space grade power system. Analog has also introduced radiation-hardened ICs for use in high ionizing dose environments, ideal for small satellites.
The company noted that mass adoption of radiation-hardened sensors is suppressed because of the technological complexity of making the products. Sensors that resist high levels of high-grade materials like SiC, GaN and diamond substrates. Sometimes the designs require hardening with enclosed layout transistors and redundant designs. Certification and testing are time-consuming and products may require years to be validated. Also, foundry capacity is limited and wide-bandgap materials are limited.
