How Does a Skin Sensor Work? Skin sensors typically operate based on the following principles:

1. Sensing Biological Signals:
   • Electrical signals: Measuring electrical signals like electrocardiograms (ECG) and electromyograms (EMG).
   • Optical signals: Using light to measure blood flow and oxygen saturation.
   • Chemical signals: Analyzing sweat components to assess health conditions.
   • Mechanical signals: Measuring mechanical changes like blood pressure and respiration.
2. Signal Conversion: Converting the detected biological signals into electrical signals.
3. Data Processing: Processing the digital signals and extracting meaningful information.
4. Data Transmission: Wireless transmission of data to other devices such as smartphones or computers.
