BioInstrumentation final project ideas

• Blood pressure
  • Arm pulse/ox and ECG to get vital signs (including blood pressure by P-wave velocity)
  • Doppler blood flow meter
  • Blood pressure cuff.
• ECG/heart
  • ECG using capacitative electrodes on arm or fingers.
  • ECG using RF coupled passive sensors.
  • ECG with advanced QRS detection.
  • ECG with improved noise removal (example)
  • Electronic stethoscope and heart sound analysis.
  • Transistor hardware model of the heart with model pacemaker and defibrillator.
• Impedance
  • GSR and skin impedance measurement.
  • Impedance tomography.
• Eye
  • Eye-motion measurement by IR or camera or electro-ocular methods.
  • Pupil servo cnaracterization (example)
• Functional imaging
  • IR tomography -- Functional Near-Infrared brain imaging.
• EMG
  • Correlate and model IR reflectance with EMG.
• Oscillators
  • Hardware model of gene oscillator
  • Nonlinear oscillator synchronization (firefly problem)
• Infrastructure/instrumentation
  • Analog adaptive 60 Hz filter. (LMS or other algorithms)
  • Adaptive filters for ECG/EMG (example)
  • Eliminate the DAQ6008 interface and use audio input to the computer.
• Joint/sports
  • Wireless knee angle sensor.
• Acoustic
  • Measure head-related transfer function and synthsize sound using it.
  • Oto-acoustic response
