3. Smart healthcare
• Applications of a smart healthcare system:
1. Human activity recognition using wearable sensors
2. Channel State Information (CSI) based human activity
recognition
3. Human health monitoring

4. Human activity recognition using wearable sensors
• Electromyography (EMG): To assess the health of
muscles.
• Electroencephalograph (EEG): To detect abnormalities in
the brain waves.
• Electrocardiogram (ECG): To record electrical activity of
the heart.
• Accelerometer (ACC): To measure acceleration of the
body.
• Electrodermal Activity (EDA): To measure changes in the
electrical properties of the skin.
• Respiration (RESP): To measures breathing rate.
• Force (FSR): To detect numbness of the body.
• Temperature (TEMP): To measure body temperature.
