A sensor (in English: transducer/sensor) is a detection device that can sense the information being measured and convert the sensed information into electrical signals or other required forms of information in a certain pattern to meet the requirements for information transmission, processing, storage, display, recording, and control [3] [5]. The national standard GB/T 7665-2005 defines it as “a device or apparatus that can sense the measured quantity and convert it into an available output signal according to certain rules, usually consisting of a sensitive element and a conversion element” [3]. The existence and development of sensors have enabled objects to possess perception functions such as touch, taste, and smell, among others. Their characteristics include miniaturization, digitization, intelligence, multi-functionality, systematization, and networking. They are the primary link for achieving automatic detection and automatic control [2]. The new type of aluminum nitride sensor can operate at temperatures around 900°C, setting a new record for the highest working temperature of piezoelectric sensors [2]. The 2025 Intelligent Sensor Industry Development Conference in Hefei was held, and Lu Yang District of Hefei created a 100-billion-yuan intelligent sensor industrial cluster, establishing an “One Port Seven Parks” industrial ecological pattern [6]. In the same year, 46 projects were signed at the Zhengzhou Sensor Conference, with a total amount exceeding 26 billion yuan, and the “Declaration of High-Quality Development of Sensors in China” was released [7]. The Xinjiang Institute of Physical Science and Technology of the Chinese Academy of Sciences developed a 40-micron-thick ultra-thin temperature sensor, using a water-soluble sacrificial layer-assisted transfer technology, with a resistance temperature coefficient of -4.1%/℃ [9]. The team from the Hong Kong University of Science and Technology developed the DM-Tac W tactile sensor, integrating 40,000 sensing units in the area of a fingernail, and passing a 5 million times pressing test [8]. Chuan Dong Magnetic Electronics obtained a patent for a new type of Hall sensor, enhancing the impact resistance through the design of protective shells and shock-absorbing components [10]. Bosch applied for a patent for sensor data processing, improving the accuracy of environmental detection through multi-dimensional data models [11].
