Sensors: The Hottest “Perception Engine” in the Era of Intelligent Connectivity

In 2026, when we talk about Industry 4.0, Made in China 2025, smart cities, autonomous driving, or wearable health, one term appears everywhere yet is often underestimated—sensors.

They are not just optional accessories but the "eyes, ears, and skin" of the entire intelligent system. Without high-precision, low-power, multifunctional sensors capable of extreme environments, even the most advanced algorithms, 5G-A networks, and edge computing remain on the PPT stage.

The Ministry of Industry and Information Technology has repeatedly emphasized that sensor and chip technology are the key breakthroughs for IoT. Globally, surging mobile devices, popular wearables, and the explosion of IoT are pushing sensor demand to trillion-level scales. IDC data shows that sensors and related modules account for about 32% of total IoT industry output, serving as a decisive growth engine.

Global Innovation Wave: Accelerating from Lab to Commercialization

Research institutions and companies overseas are rapidly redefining sensor boundaries.

• Monash University in Australia solved flexible bending and stretching issues for wearable sensors. These skin-like biosensors can continuously capture biomarkers such as sweat and skin conductance in remote health monitoring.

• A consortium of four top UK universities focuses on “smart sensor systems,” aiming to create next-generation sensors with higher autonomy and long-term stability, empowering smart cities, big data analytics, and L3/L4 autonomous driving.

• Sweden's Fingerprint Cards has made fingerprint recognition “invisible” by integrating under-display fingerprint sensors beneath the glass. Users can unlock devices by touching designated areas without home or side buttons, enhancing industrial design freedom.

These breakthroughs are not isolated cases but represent the global shift from “traditional” to “new-generation” sensors.

Five Core Features of New Sensors: From Miniaturization to Networking

• Miniaturization: MEMS processes shrink sensor sizes to millimeters or even microns, enabling integration in phones, wearables, and industrial devices.

• Digitalization: Native digital output reduces analog noise and improves system compatibility.

• Intelligence: Embedded edge AI enables local feature extraction, anomaly detection, and self-calibration.

• Multi-functionality: Single-chip sensors integrate multiple parameters such as temperature, pressure, humidity, and gas sensing.

• Networking: Support wireless mesh networks and low-power wide-area communication (LoRa, NB-IoT, Thread) to achieve “perception of everything.”

Sensor Market Landscape: Flow, Pressure, and Temperature Dominate; Emerging Tracks Poised to Explode

Traditional categories still dominate the global sensor market:

• Flow sensors: ~21% market share, widely used in industrial process control and energy metering.

• Pressure sensors: 19%, core for automotive tire monitoring and hydraulic systems.

• Temperature sensors: 14%, essential for almost all smart devices.

However, the fastest-growing sectors are emerging directions:

• Wireless sensor networks (WSN): flexible deployment in industrial sites without wiring.

• MEMS sensors: driven by consumer electronics and automotive electronics.

• Biosensors: the next hotspot for health monitoring and precision medicine.

Photoelectric sensors exemplify this trend. In 2014, China produced 450 million units, with a demand of 250 million units. Today, these numbers have multiplied, penetrating optoelectronic detection, smart lighting, and security monitoring.

China’s Sensor Industry: Policy Boosts Create a Golden Window

Although core technology gaps remain, China’s sensor industry is rapidly catching up under strong policy guidance.

Made in China 2025 and Industry 4.0 aim for intelligent production, with sensors at the forefront. National investment continues to promote domestic chips, sensitive materials, and packaging/testing processes.

Simultaneously, downstream applications like IoT security, smart homes, and connected vehicles are booming, driving demand for high-reliability sensors. By 2030, China is expected to become one of the largest global sensor consumption markets.

Future Trends: Complexity, Functionality, Safety, and Customization

From 2026 to 2030, sensor companies must innovate along these dimensions:

• Complex environment adaptation: high temperature, corrosion resistance, electromagnetic interference protection.

• Real-time intelligent processing: embedded AI accelerators for edge signal preprocessing.

• Safety and reliability: hardware-level encryption, self-diagnosis, and self-repair mechanisms.

• High customization: collaborate with customers to develop solutions tailored to specific scenarios.

Meeting these standards allows companies to stand out in the competitive components market and create truly differentiated value for clients.
