Sensor Nobleman Technology: A Pioneer in the Localization of High-End Pressure Sensors
The sensor industry is a fundamental and strategic sector of the national economy. It provides essential core technologies and equipment indispensable for national defense facilities, major engineering projects, and critical industrial equipment. Yet, China finds itself in a vulnerable position—“choked” by Western countries—in many fields, especially in high-end industrial sensors. The degree of dependency on foreign suppliers in this area is even more severe than that for chips: in the realm of precision instruments and meters, nearly 100% of sensors are imported! In today’s era, marked by the vigorous development of information technology and the digital economy, as well as the burgeoning growth of the Internet of Things, the importance of sensors—situated at the forefront of intelligent sensing and serving as the very source of data collection—is self-evident. We are currently witnessing a once-in-a-century shift toward “deglobalization.” Under the country’s 14th Five-Year Plan, the primary and critical task is to overcome bottlenecks in core technologies, integrate both domestic and international resources, and enhance the security, stability, and high-end sophistication of industrial and supply chains—thereby breaking through external constraints imposed by other countries and opening up the “internal circulation”!

[Patent Introduction] A Small-Volume High-Temperature Pressure Transmitter
“A small-size high-temperature pressure transmitter” is an invention patent—both international and domestic—that has been applied for by Suno-Meng Technology Co., Ltd. (Application No. 2019109513119). The product features a 300℃ high-temperature nanofilm pressure sensor core developed independently by the company, and it is completed through a specially designed structural configuration. The product can operate in media temperatures up to 250℃ (with potential expansion to 350℃), boasts a combined accuracy better than 0.2%FS, and has a length of less than 40 millimeters. Its output signals are either 0.5–4.5 VDC or 4–20 mA DC. This high-performance pressure transmitter is ideally suited for applications in weapon systems such as missile propulsion systems, as well as in various civilian fields.

Film Structure and Quality Requirements for Nanometer-Thick Film Pressure Sensors
The multilayer film used in nanofilm pressure sensors is fabricated using a vacuum ion-beam sputtering process. Because the thickness of the core-sensitive film is less than 100 nm, it is referred to as a nanofilm. Pressure sensors manufactured using this process are called nanofilm pressure sensors.

Nanofilm technology has significantly enhanced the stability of pressure sensors.
The main performance indicators for pressure sensors include accuracy (overall accuracy), temperature characteristics, thermal influence performance, zero-point drift, long-term stability, and reliability. Long-term stability refers to the sensor's ability to regain its originally calibrated performance when recalibrated after being used for a certain period—whether stored in a warehouse or operating online. Among the calibrated performance parameters, nonlinearity errors, temperature errors, and thermal influence errors within the overall accuracy can all be corrected and compensated for using modern electronic technologies, thereby minimizing their impact on measurement accuracy. However, zero-point drift is a random error that cannot be corrected by circuitry. Even if a sensor boasts high accuracy and other excellent performance metrics, zero-point drift often renders the measurements unreliable. Given the critical importance of zero-point drift in reproducing performance specifications, stability indicators are frequently expressed as the maximum allowable zero-point drift error over a specified period under defined conditions, typically reported in units of "% FS/year."

Preparation of Nanofilms and Enhancement of Performance of Nanofilm Pressure Sensors
In nanotechnology, the first observation was made using a scanning tunneling microscope, which employs an extremely sharp probe equipped with an enhanced electric field. Under the influence of this strong electric field, the probe can attract individual atoms and then move them to another location, arranging them into the desired structure. The multilayer thin films used in high-performance nanoscale pressure sensors are fabricated by a kinetic-energy-transfer method, in which individual atoms are excited and transported to new locations, where they are deposited to form nanoscale thin films. There are numerous reports from abroad on the use of kinetic-energy-transfer methods for atom relocation. For example, Professor Makoto Matsui of Japan has used NEC’s precision ion-beam equipment to fabricate tiny components with thicknesses less than 0.1 μm (micrometers) via ion-beam deposition technology. Abroad, there have also been reports on equipment developed specifically for surface micromachining in the fields of nanotechnology and nanomanufacturing—for instance, ion-beam mercury transfer and plating, molecular-beam epitaxy, and etching techniques using electron beams and light beams—all of which can be applied in these processes. Mr. Toshiyuki Takagi, a leading expert on thin films from Japan, pointed out that by leveraging ion-engineering, laser ablation, and laser-processing technologies to precisely control the orderliness of atoms and molecules, it is possible to create functional ultra-thin deposited films.
