Paragraph starter
The electromagnetic interaction between wearable devices and the human body is a critical consideration for reliable performance. Research, such as that by Augustine (2009), highlights the importance of using biocompatible phantom materials that accurately mimic human tissue properties when testing antenna performance for Body Area Networks. This ensures that the observed performance reflects real-world conditions, where the body can significantly attenuate or distort wireless signals. Consequently, design strategies to mitigate these effects, like incorporating ground planes, are essential for robust device functionality.
