Juntong Cui from the School of Integrated Circuits, Jiangnan University, has contributed significant research on improving the calibration of MEMS-based pressure sensors. In the paper “Design of a Rapid and Accurate Calibration System for Pressure Sensors with Minimized Temperature Variation” published in Sensors on 25 August 2025, the study addresses the challenges of nonlinearity and zero drift in mass-produced sensors. Using finite element method (FEM) simulations, the research confirms the accuracy of temperature control in the proposed calibration system while accounting for slight temperature distribution non-uniformity. A home-developed automatic calibration setup is then employed, enabling the rapid calibration of nine sensors within 80 minutes. The results demonstrate remarkable improvements, reducing linearity error from 46.5% FS to 1.5% FS and lowering the temperature coefficient from −1.35 × 10⁻⁴ V·K⁻¹ to −8.8 × 10⁻⁷ V·K⁻¹, showcasing the system’s efficiency and precision.
