Abstract
A removable tattoo for applying a pattern to the skin for use with an optical measurement system to measure forces on the skin such as during shaving. A transfer paper is printed with a random pattern of different size dots. The pattern can have two or three different sized dots. The pattern of dots has a pattern density of between about 40% to about 60%. The pattern is printed with inks suitable for skin contact that are not water soluble so as to withstand a moist shaving environment. The pattern is removable from the test person with alcohol.
Claims26
A removable tattoo for patterning a section of skin to provide a reference marking for use in optical skin deformation measurements, comprising
- a substrate (73), and
- a pattern (45) comprising a plurality of indicia randomly distributed to form a pattern density of between about 40% and about 60%.
A moisture-activated, removable tattoo for patterning a section of skin to provide a reference marking for use in optical-based skin deformation measurements, comprising
- a substrate (73), and
- a random pattern (45) comprising a plurality of distributed dots,
- said dots comprising an ink or dye, said ink or dye being substantially water insoluble and being substantially soluble in an alcohol.
