Capturing 8-12 Hz Physiological Hand Tremors on Steering Wheel Sensors
Using piezoelectric ceramic accelerometers embedded in the steering armature to isolate metabolic tremor bands from coarse mechanical chassis vibrations.
Spectral Energy Concentration
Power spectral density analysis reveals a sharp surge in the 8-12 Hz band that correlates with blood glucose drops below 55 mg/dL, prompting an early roadside pullover.
- Detects hypoglycemia up to 20 minutes before neuroglycopenic confusion.
- Real-time FFT and power spectral density evaluation on steering wheel signals.
- Zero wearable medical sensor patches required on the driver's body.
- Automated in-cabin prompt advising immediate carbohydrate consumption.
