TRUSEE

Qiushi Future (English brand TRUSEE), relying on Tsinghua University, The top scientific research team of Northwestern University of Technology and China University of Science and Technology has been formed as a benchmark enterprise for high-precision sensing of MEMS in the whole stack of domestic research and development, received a yuan-level A round of strategic investment in Zhejiang province's industrial investment, and filled the gap in the high-performance inertial sensing industry chain in Zhejiang. It has a complete intellectual property self-development system, has a whole-process patent layout for MEMS chips, and realizes the capability of MEMS wafer architecture design, ASIC signal development, precision TO / patch packaging, factory calibration in multi-temperature zones, and algorithm adaptation in the whole chain, localized and controllable mass production. In the future, we will explore three core technical routes: high-performance MEMS inertial measurement, infrared thermoelectric reactor non-contact temperature measurement, NDIR / electrochemical gas detection, self-developed structure of precipitation MEMS resonant accelerometer, anti-interference gyroscope process, IMU multi-axis fusion algorithm, infrared thermal reactor wafer microfabrication, The whole set of self-developed processes for gas-sensitive materials marking, high-temperature multidimensional compensation has been developed, and five core product lines have been developed: MEMS accelerometer, MEMS gyroscope, six-axis / nine-axis IMU inertia unit, infrared thermoelectric reactor temperature sensor, and multi-category gas sensors (CO2, TVOC, flammable gas). Full-system inertial chip equipped with on-chip ADC, EEPROM, mainstream support SPI, I2C digital communication output; Different from ordinary consumer MEMS devices, relying on self-developed resonant isolation structure, original full-temperature full-field multi-point calibration, with very low zero bias drift, strong anti-vibration, anti-stray magnetic field advantages; The infrared series relies on the thermopile infrared radiation temperature measurement, and is not affected by the temperature drift of the RTD resistance. The gas sensors go out of factory to complete cross compensation of temperature and humidity, and the vast majority of models do not require a customer to adjust themselves twice. With the core advantages of high precision and low noise, high temperature stability in a wide temperature range, resistance to adverse environmental disturbances, rich packaging forms, stable batch shipment consistency, and high military / industrial / automotive multi-scenario embedded adaptability, it has widely entered defense and military navigation, aerospace, The field of oil drilling, drones, humanoid robots, autonomous driving, industrial automation, new wind and heating, cold chain temperature control, environmental monitoring, smart home, medical temperature measurement, has reached long-term stable strategic cooperation with domestic military research institutes, head robot companies, industrial control, and vehicle manufacturers. Following the two strict quality control standards of military industry and industrial industry, Hangzhou headquarters R & D general base, Suzhou R & D quantitative production center, multi-site external co-testing production line, and domestic whole-area distribution support a localized delivery system that can scale the inertia of mass supply. Infrared and gas sensors have a large number of patents for MEMS structure, packaging, calibration, and algorithm inventions, and can provide standardized sensing components, customized range customized calibration schemes, special packaging development, supporting drive algorithms, and complete original factory specifications. In the future, TRUSEE, as the national high-precision MEMS inertial sensing leader, takes into account the high-end needs of military industry and the high-volume market of civil uses, continues to promote the domestic substitution of high-end sensors, and solidifies the advantages of domestic inertial awareness, infrared temperature measurement, and gas detection.
