Paragraph starter
The interaction of millimeter-wave radiation with the human body is a critical consideration for wearable technology. Research indicates that these frequencies can cause localized thermal effects, primarily heating superficial tissues due to their low penetration depth. This necessitates careful design to manage heat dissipation and minimize direct exposure, ensuring user comfort and safety. For instance, the specific absorption rate (SAR) and resulting temperature rise are key metrics that designers must address to prevent adverse physiological responses.
