▲ [18p-221B-7] [INVITED] Helical structure of human sweat ducts and their interaction with sub-terahertz waves
キーワード：terahertz, spectroscopy, sweat duct
The applications of terahertz (THz) waves have expanded into diverse fields such as homeland security, information and communication technology and non-destructive testing and analysis. Due to the use of THz wave in such applications, encounters between THz radiation and humans are expected to become common. Therefore, knowledge of the fundamental principles of THz wave interaction with human beings is crucial for understanding the various health consequences. Some studies have demonstrated that the sweat glands present in the human skin play a critical role in THz wave interaction with human beings. It was reported that the sweat ducts act as a helical antenna due to their helical structure and resonate in the terahertz frequency range. Here, we present the morphological features of human sweat ducts and their frequency of resonance in different modes of operation known as axial mode and normal mode.
