The dynamics of fingertip contact manifest themselves in the complex skin movements observed during the transition from a stuck state to a fully developed slip. While investigating this transition, we found that it depended on skin hydration. To quantify this dependency, we asked subjects to slide their index fingertip on a glass surface while keeping the normal component of the interaction force constant with the help of visual feedback. Skin deformation inside the contact region was imaged…

A review of fingerpad contact mechanics and friction and how this affects tactile perception

In the sliding contact between the fingerpad and a rough surface when touching a product’s surface, friction plays a role in the perception of roughness, slipperiness and warmth. For product…

Surface strain measurements of fingertip skin under shearing

The temporal evolution of surface strain, resulting from a combination of normal and tangential loading forces on the fingerpad, was calculated from high-resolution images and it is concluded that some of these deviations depend on local fingerprint patterns.

Biomechanics of Finger Pad Response under Torsion

Surface skin deformation of the finger pad during partial slippage at finger-object interfaces elicits tactile feedback. During object manipulation, torque is often present, which can cause partial…

Dynamics of fingertip contact during the onset of tangential slip

It is concluded that the complex, but highly patterned and reproducible, deformations measured in this study are a potential source of information for the central nervous system and that further mechanical measurement are needed to better understand tactile perceptual and motor performances.

How to Measure the Area of Real Contact of Skin on Glass

Two methods to measure the variations of contact area are presented; one that improves upon a tried-and-true fingertip imaging technique to provide ground truth, and the other that relies on the absorption and reflection of acoustic energy.

Fast Grip Force Adaptation To Friction Relies On Localized Fingerpad Strains

A significant increase in skin deformation inside the contact area arising over 100ms before the motor response, during the loading phase, is found, suggesting that local and partial deformation patterns prior to lift-off are used in the nervous system to adjust the grip force as a function of the frictional condition.

Role of Occlusion in Non-Coulombic Slip of the Finger Pad

An investigation of the relationship between occlusion and the non-Coulombic slip of the finger pad, which results in the frictional force being a power law function of the normal load, with an index n, shows that the power law index tends to a value in the range of 2-3.

University of Birmingham Why do pens have rubbery grips?

The process by which human fingers gives rise to stable contacts with smooth, hard objects is surprisingly slow. Using high-resolution imaging we found that, when pressed against glass, the actual…

Finger pad friction and its role in grip and touch

Many aspects of both grip function and tactile perception depend on complex frictional interactions occurring in the contact zone of the finger pad, which is the subject of the current review. While…

A continuous measure of fingertip friction during precision grip

Dynamic contact of the human fingerpad against a flat surface.

A model based on the contact of a rigid plane and a linear viscoelastic sphere, modified to include a nonlinear modulus of elasticity, can account for the principal features of the distributed pressure response.

Characteristics of human fingertips in the shearing direction

Impedance characteristics of the human fingertips in the tangential directions to the tip surface are described and it is shown that the average strain rate of the fingertip in theTangential direction to the fingertips surface became slower and converged to a constant value with higher contact forces.

Review of the frictional properties of finger-object contact when gripping

Abstract Gripping is an everyday task which is taken for granted by many. The current paper examines extant knowledge of howobjects are gripped for manipulation, and the relationship, the coefficient…

Fingertip moisture is optimally modulated during object manipulation.

A modulation of the grip force with moisture level is shown and novel mechanisms of moisture regulation that tend to stabilize the moisture level toward the value that minimizes grip force are hypothesized.

Fingerprints are unlikely to increase the friction of primate fingerpads

Investigating the frictional performance of human fingertips on dry acrylic glass using a modified universal mechanical testing machine showed that fingertips behaved more like rubbers than hard solids; their coefficients of friction fell at higher normal forces and friction was higher when fingers were held flatter against wider sheets and hence when contact area was greater.

An investigation of the mechanics of tactile sense using two-dimensional models of the primate fingertip.

The role of mechanics in the neural coding of tactile information is investigated using simple models of the primate fingertip and strain energy density is found to be a better candidate to be the relevant stimulus for SAIs.

Friction, not texture, dictates grip forces used during object manipulation.

Friction appears to be a more important factor in determining the grip force than either texture or surface films at least for the range of textures and coatings examined in this study.
