Fingertip Force Measurement by Imaging the Fingernail
Shear and normal forces from fingertip contact with a surface are measured by external camera images of the fingernail. Due to mechanical interaction between the surface, fingertip bone, and fingernail, regions of tension or compression are set up that result in reddening or whitening due to blood flow. The effect is quantitative enough to serve as a transducer of fingertip force. Due to indivi...
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 کاملEstimating Gaussian curvatures from 3D meshes
A new approach to estimate the surface curvatures from 3D triangular mesh surfaces with Gaussian curvature’s geometry interpretation is proposed in this work. Unlike previous work, the proposed method does not use local surface fitting, partial derivative computation, or oriented normal vector recovery. Instead, the Gaussian curvature is estimated at a vertex as the area of its small neighborho...
متن کاملForces and torques on rotating spirochete flagella.
Spirochetes are a unique group of motile bacteria that are distinguished by their helical or flat-wave shapes and the location of their flagella, which reside within the tiny space between the bacterial cell wall and the outer membrane (the periplasm). In Borrelia burgdorferi, rotation of the flagella produces cellular undulations that drive swimming. How these shape changes arise due to the fo...
متن کاملMicroscopic Calculation of Spin Torques and Forces
Spin torques, that is, effects of conduction electrons on magnetization dynamics, are calculated microscopically in the first order in spatial gradient and time derivative of magnetization. Special attention is paid to the so-called β-term and the Gilbert damping, α, in the presence of electrons’ spin-relaxation processes, which are modeled by quenched magnetic impurities. Two types of forces t...
