Sensors are an important component of various electronic devices. Most of the motion sensors in China rely on imports. However, Nanjing University of Science and Technology recently announced that motion sensor technology can be made domestically, breaking the monopoly of foreign countries.

Did you know that the sensors that we use every day to measure movement parameters such as sport bracelets, pedometers, and car navigation are imported? A research result of Professor Su Yan from Nanjing University of Science and Technology can not only localize this technology, break foreign monopoly, but also lead the world in certain technical indicators. Recently, the research results have been published in the top international periodical "Solid State Circuit Journal" in the field of microelectronics and integrated circuits.

"The sensor that measures motion parameters is also called inertial sensor. It consists of an accelerometer and a gyroscope. It can measure the acceleration, tilt, impact, vibration, and rotation of an object in real time, realizing the real-time monitoring of the position and motion information of the carrier." South University Inertial Sensor The team leader Professor Su Yan introduced that the existing domestic inertial sensors have added a whole set of signal detection, signal processing and other circuit systems to the periphery of the design. The volume is relatively large, the performance is unstable, and it is difficult to use on mobile phones, navigation and other electronic products. Their team through design and development, the circuit system around the sensor are all integrated in a small chip, so that the performance of the sensor has been improved, the volume is greatly reduced.

Su Yan introduced that although China is a major producer of electronic products, the core components such as inertial sensors involved in the products have long been dependent on imports. "On the market, more than 90% of consumer electronics products use the core components purchased from foreign countries, and the domestic market is only integrated and assembled." Su Yan said that this research made China's own production of consumer electronics products. Needed inertial sensors become possible.
