3-Axis accelerometer characterization: A dynamic analysis varying the operating temperature

In today's technological landscape, precise sensing solutions are increasingly required for diverse applications across industries. MEMS (Micro Electro-Mechanical Systems) accelerometers are crucial in automotive systems for positioning estimation and fault diagnosis. Despite their increasing role, still remains a research gap in understanding sensor's performance under temperature and motion dynamic conditions. Indeed, existing literature overlooks the impact of the actual operating conditions on the sensor metrological performances. This study addresses this gap by presenting a preliminary characterization of a 3-axis MEMS-based accelerometer under varying temperatures and various motion conditions, simulating a real-world automotive environment in a reproducible laboratory testbed. Results reveal significant drift and uncorrelated behavior between temperature and sensor response, highlighting the necessity for comprehensive sensor characterization. Such findings offer valuable insights for enhancing sensor reliability and accuracy in diagnostic applications.
