Cosmetic camouflage

Journal of Cosmetic Dermatology, 2006
SummaryAlthough many skin conditions are amenable to treatment, on certain occasions dermatology and plastic surgery have not much to offer and patients are left with disfigurements. Cosmetic camouflage is a therapy that has been developed to alleviate the suffering of those who have been disfigured by a congenital or an acquired lesion and who have no

Design of an omnidirectional camouflage device with anisotropic confocal elliptic geometry in thermal-electric field

iScience, 2022
Summary: The designed confocal elliptical core-shell structure can realize the omnidirectional camouflage effect without disturbing temperature and electric potential profiles as the directions of heat flux and electric current change.
