Fingernail Configuration
BACKGROUND A number of conditions can alter a person's fingernail configuration. The ratio between fingernail width and length (W/L) is an important aesthetic criterion, and some underlying diseases can alter the size of the fingernail. Fingernail curvature can be altered by systemic disorders or disorders of the fingernail itself. Although the shape and curvature of the fingernail can provide ...
متن کاملGenetic analysis using fingernail DNA.
For the genetic analysis with the polymerase chain reaction (PCR), template DNA is generally prepared from blood cells. However, in some instances, when blood samples are not available, DNA from hair can be used for the analysis (1, 2). Both mitochondrial DNA (mtDNA) and nuclear DNA can be amplified using DNA extracted from one hair. While hair sampling is easy, there are still some problems, e...
متن کاملUnderstanding of Fingernail-Bone Interaction and Fingertip Hemodynamics for Fingernail Sensor Design
When the human fingertip is pressed against a surface or bent, the hemodynamic state of the fingertip is altered due to mechanical interactions between the fingernail and bone. Normal force, shear force, and finger extension/flexion all result in different patterns of blood volume beneath the fingernail. This phenomenon has been exploited in order to detect finger forces and finger posture by c...
متن کاملForce Prediction Using Fingernail Imaging: An Overview
This paper presents a method for automatically calibrating a fingernail imaging system used to detect arbitrary three-dimensional force on the human fingerpad. The calibration is accomplished using a Magnetic Levitation Haptic Device modified to apply calibrated forces through a flat plate to the fingerpad. The technique explained here is shown to accurately predict arbitrary shear force with R...
متن کاملFingernail Displays: Handy Displays at your Fingertips
Humans are mostly using their fingers to interact with their environment. We introduce our vision of Fingernail Displays: tiny displays that are worn on the fingernails. We describe and explore the following application scenarios of fingernail-worn displays: (1) FingerPhone, a standalone device for fast, lightweight interaction that is always at hand; (2) on-finger output on touch displays, whi...
