In humans, the tactile perception of fine textures (spatial scale <200 micrometers) is mediated by skin vibrations generated as the finger scans the surface. To establish the relationship between texture characteristics and subcutaneous vibrations, a biomimetic tactile sensor has been designed whose dimensions match those of the fingertip. When the sensor surface is patterned with parallel ridges mimicking the fingerprints, the spectrum of vibrations elicited by randomly textured substrates is… Expand
Effect of fingerprints orientation on skin vibrations during tactile exploration of textured surfaces
TLDR
Test the hypothesis that fingerprints may play an important role in shaping the subcutaneous stress vibrations in a way which facilitates their processing by the PC channel by directly recording the modulations of the fingerpad/substrate friction force induced by scanning an actual fingertip across a textured surface.

A Biomimetic Fingerprint Improves Spatial Tactile Perception
TLDR
The biomimetic fingerprint acts as an amplifier of high spatial frequencies, and provides evidence to suggest that the perception of high temporal frequencies is also one of the functions of the human fingertip. Expand

TLDR
Results from human microneurography experiments were performed and a selection of results is included in this work in order to support the significance of the biorobotic study with the artificial tactile system. Expand
The role of mechanical stimuli on hedonistic and topographical discrimination of textures
Abstract Recognition of texture properties requires sliding contact between finger and object surface. Although it is well known that vibrations stimulate the tactile afferents, the mechanism byExpand
Texture-induced vibrations in the forearm during tactile exploration
TLDR
The spectral analysis of the vibrations taking place in the forearm tissues revealed regularities that were correlated with the scanned surface and the speed of exploration, suggesting that the somatosensory system is able to collect textural information from other sources than fingertip afference.

Addition of a Biomimetic Fingerprint on an Artificial Fingertip Enhances Tactile Spatial Acuity
TLDR
This work endow a biomimetic sensor with both papillary ridges (fingerprint) and a dermal stiffness contrast (stiffer intermediate ridges) and demonstrates that the addition of a fingerprint to an artificial tactile sensors improves its acuity. Expand
Investigation of the role of contact-induced vibrations in tactile discrimination of textures
Tactile perception of texture is meaningful for numerous industrial and social applications. While the sense of touch is provided by several contributing factors, each related to different sensoryExpand
The Role of Exploratory Conditions in Bio-Inspired Tactile Sensing of Single Topogical Features
TLDR
It is demonstrated that the knowledge of these characteristic responses allows one to dynamically evaluate the position of a small hole within the contact zone, based on the micro-force sensors signals, with a spatial resolution an order of magnitude better than the intrinsic resolution of individual sensors.

Fingerprint-Inspired Flexible Tactile Sensor for Accurately Discerning Surface Texture.
TLDR
To demonstrate the texture discrimination capability, the sensors are tested for accurately discerning various surface textures, such as the textures of different fabrics, Braille characters, the inverted pyramid patterns, which will have great potential in robot skins and haptic perception, etc. Expand

Tactile detection of slip: surface microgeometry and peripheral neural codes.
TLDR
The results show that surprisingly small features on smooth surfaces are detected by humans and lead to the detection of slip of these surfaces, with the geometry of the microfeatures governing the associated neural codes. Expand
The vibrations of texture
TLDR
It is proposed that the roughness of a fine surface (spatial period<200 7 m) is a function of the Pacinian-weighted power of the vibrations it elicits, which is found to decrease systematically as spatial period increases. Expand

Evidence for the duplex theory of tactile texture perception
TLDR
Two components of stimulation (presumably vibrational and spatial) contribute to texture perception, as Katz maintained; mechanisms for responding to the latter appear to be engaged at texture element sizes down to 100 ^m, a surprisingly small value. Expand

It is suggested that the textural information conveyed by the Pacinian system concerns surface roughness and, possibly, stickiness. Expand

TLDR
The findings indicate that the RA and SA I units are well suited for the analysis of mechanical events on the skin surface with a high degree of spatial selectivity, whereas the PC and SA II units are suited for analysis of other mechanical events, e.g. vibration and various forms of tension in the skin and related tissues.

Both the lateral and height resolution of texture are comparable to the human finger at similar stress levels of ∼10 kilopascals, and the change in current density through the film and the electroluminescent light intensity are linearly proportional to the local stress. Expand
