This paper deals with simultaneous classification of shape, size, and softness of cylindrical objects by using soft tactile sensor array system of a five-links single robotic finger using the most effective 7 kinds of 8-cells patterns.
Proposal of a Micromachined Tactile Sensor Having Four Stories and Its Information Processing Method using Module Networks
Imitating the human skin structure, an arrayed type tactile sensor composed of many force sensing elements distributed on four stories is proposed. The information processing method for this sensor
Development of an Arrayed Tactile Sensor Having Four Stories and Recognition of Contact State Using Neural Networks
In the human skin, four kinds of tactile receptors are distributed three dimensionally, i.e., not only on the skin surface but also in the four corresponding depths of the skin. Imitating this, a
Presenting Surface Features Using a Haptic Ring: A Psychophysical Study on Relocating Vibrotactile Feedback
In the context of the haptic ring being developed, these findings indicated that it is feasible to display information experienced at the fingertip on a more proximal location on the hand, thus freeing the fingers for other tasks.
Recent Progress in Technologies for Tactile Sensors
State-of-the-art tactile sensors are reviewed in terms of their diverse sensing mechanisms, design consideration, and material selection, and two major potential applications of tactile sensing systems are discussed in detail.
A method for abstraction and reproduction of environment based on frequency characteristic
A method for abstraction and reproduction of the environmental stiffness based on the frequency characteristic is proposed and the validity of the proposed method is shown by experimental results.
Tactile display with rigid coupling based on soft actuator
The tactile display is a device which physically stimulates the human skin to reproduce the feel of touch. This paper presents a novel tactile display device driven by a dielectric elastomer
An endoscopic tactile sensor for low invasive surgery
In order to improve the manipulation ability of endoscope, we have developed a new tactile sensor system using image processing. As this system uses an infrared (IR) cut pattern, it is possible to
A tactile synthesis method using multiple frequency vibrations for representing virtual touch
A total texture feeling display combined with the methods for roughness, pressure, and friction sensations showed that some combinations of multiple tactile sensations could express texture feels of the expected materials.
Highly Transparent and Integrable Surface Texture Change Device for Localized Tactile Feedback.
A new concept for on-demand surface texture augmentation that is capable of physically forming local topographic features in any predesigned pattern is demonstrated and highly useful for applications such as display touchscreens, touchpads, braille displays, on- demand buttons, and microfluidic devices.


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.
The sense of flutter-vibration: comparison of the human capacity with response patterns of mechanoreceptive afferents from the monkey hand.
This paper combines two experimental of the first importance for sensory neurophysdesigns which differ remarkably in method, iology, for they establish the dynamic and in their historical and conceptual derange required of the input on the afferent side of the system to account for the output-the measured sensory capacities.
Properties of cutaneous mechanoreceptors in the human hand-related to touch sensation
Recordings from single peripheral nerve fibres made it possible to analyse the functional properties of tactile afferent units supplying the glabrous skin of the human hand and to assess directly the

It is found that it is not possible to reliably deduce the difference between contacting the sensor's surface with various axisymmetric objects.
Contact mechanics
Contact problems are central to Solid Mechanics, because contact is the principal method of applying loads to a deformable body and the resulting stress concentration is often the most critical point
A model accounting for effects of vibratory amplitude on responses of cutaneous mechanoreceptors in macaque monkey
Almost all of the response properties studied here were accounted for by the equivalent circuit model; changes in membrane time constant and amplitude sensitivity accounted for the differences between the three mechanoreceptive fibre types.
