Piezoresistive Pressure Sensor Zero Drift under Variable Atmospheric Humidity
Dynamic atmospheric humidity alters gel swelling stress and dielectric passivation properties in piezoresistive sensors, driving measurable zero baseline drift.
Prony Series Deconvolution of Viscoelastic Die Attach Relaxation in Accelerometers
Real-time digital inverse Prony filtering decouples time-dependent polymer stress relaxation from true acceleration signals in high-precision micro-sensors.
State-Space Thermal Observer Firmware Implementation for Tactical Inertial Measurement Units
Real-time state-space thermal observers reconstruct unmeasured internal temperature gradients to eliminate dynamic bias drift in tactical MEMS IMU firmware.
Modeling Non-Stationary Bias Drift across Thermal Gradients in Extended State Estimators for Tactical Sensors
Dynamic thermal gradients induce non-stationary bias drift in tactical sensors; state estimators must augment state vectors with thermal rate terms.
Ground Alignment Metrics for Inertial Sensor Bias Drift Estimation
Static ground alignment accuracy depends on isolating Earth rotation rate from sensor bias instability through multi-position indexing and Allan variance metrics.
