OPTICAL MEASUREMENT METHOD OF SKIN STRAIN DURING SHAVING
摘要
<p>A contact-less, optical method of measuring strain on a skin surface of a human test subject during shaving. Digital cameras record the deflection of a pattern applied to the skin as a series of digital images. Comparison of the deflected skin position under applied forces compared to an undeflected reference condition permits calculation of the strain in the skin. Strains in the skin are averaged over several positions of the razor blade unit during a stroke. Objective comparisons can be made between razors based on the strain data.</p>
