It is demonstrated that the thermal origin of the excess wing in the THz portion of the dielectric spectrum of water is the same as that of the main dielectric peak. The implication is that models positing the free rotation of water molecules to account for the Excess wing are not correct. A self-terminating Proton cascade is one possible explanation.
Recent publications show strong correlation between the sub-THz reflection coefficient of a human skin and various stress related ECG parameters. The main hypothesis explaining the phenomenon is based on the coiled nature of human sweat ducts. The way to the development of disruptive commercial applications exploiting this phenomena, traverses through multi-pixel imaging of the human skin tissue (in...
The sub-THz reflectance of the Human palm was imaged while the person was subjected to varying degrees of stress. The pattern of individual pixel intensity and their correlation to stress matched the actual physical distribution of sweat pores on the hand surface. This fact is put forward as a possible novel biometric avenue.
