“…There were two categories of these materials used in this tactile discrimination study: surface roughness and material hardness. All of these samples were prepared under the same laboratory conditions (25 °C and relative humidity (RH) 55%) and appropriately cleaned by relevant approaches with ethanol or acetone solutions, as mentioned in a previous study [ 14 ].…”

“…The interlocked microstructures between the epidermal and dermal layers of the skin are supposed to be functional amplifiers and efficiently transfer the tactile stimulation to various cutaneous mechanoreceptors [ 9 , 10 ]. Within human skin, slowly-adapting (SA) receptors, such as Merkel and Ruffini corpuscles, respond to sustained touch and pressure on the skin, and rapid-adapting (RA) receptors, for example, Meissner and Pacinian corpuscles, respond to dynamic touch and vibration stimuli [ 11 , 12 , 13 , 14 ]. All of these mechanoreceptors enable humans to precisely perceive and discriminate mechanical and thermal stimuli.…”

“…Complex mechanical fluctuations take place, as well as the transitory phases between sticking and slipping, during the fingertip scanning of a material’s surfaces for a range of rubbing velocities and loads. As shown in Figure 1 , when the fingertip reciprocatingly rubs the material’s surface with increasing rubbing velocity and pressing normal loads, various vibration signals are detected by the mechanoreceptors distributed in the skin dermis of the fingertip [ 14 ] and are conducted to the nerve fibers, then finally recognized by the human brain [ 40 ]. Figure 1 a,b presents a simplified schematic of human roughness and hardness tactile perceptions, which illustrate the correlation of surface textures and interfacial deformations as a function of sliding velocity and normal load at the interface between the fingertip and the material surface.…”

The human fingertip is an exquisitely powerful bio-tactile sensor in perceiving different materials based on various highly-sensitive mechanoreceptors distributed all over the skin. The tactile perception of surface roughness and material hardness can be estimated by skin vibrations generated during a fingertip stroking of a surface instead of being maintained in a static position. Moreover, reciprocating sliding with increasing velocities and pressures are two common behaviors in humans to discriminate different materials, but the question remains as to what the correlation of the sliding velocity and normal load on the tactile perceptions of surface roughness and hardness is for material discrimination. In order to investigate this correlation, a finger-inspired crossed-I beam structure tactile tester has been designed to mimic the anthropic tactile discrimination behaviors. A novel method of characterizing the fast Fourier transform integral (FFT) slope of the vibration acceleration signal generated from fingertip rubbing on surfaces at increasing sliding velocity and normal load, respectively, are defined as kv and kw, and is proposed to discriminate the surface roughness and hardness of different materials. Over eight types of materials were tested, and they proved the capability and advantages of this high tactile-discriminating method. Our study may find applications in investigating humanoid robot perceptual abilities.

“…Various types of rapidly and slowly adapting mechanoreceptors are distributed throughout the body and function as selective encoding devices for the detection of various mechanical stimuli, including touch, stretch, vibration, and textures . As the rapidly adapting mechanoreceptors, Meissner corpuscles perceive dynamic skin deformation and slip motion in the frequency range from 10 to 60 Hz, and Pacinian corpuscles, which are the most sensitive receptors, perceive the high‐frequency vibratory stimuli in the range from 50 to 1000 Hz.…”

Electronic skin (e-skin) technology is an exciting frontier to drive the next generation of wearable electronics owing to its high level of wearability, enabling high accuracy to harvest information of users and their surroundings. Recently, biomimicry of human and biological skins has become a great inspiration for realizing novel wearable electronic systems with exceptional multifunctionality as well as advanced sensory functions. This review covers and highlights bioinspired e-skins mimicking perceptive features of human and biological skins. In particular, five main components in tactile sensation processes of human skin are individually discussed with recent advances of e-skins that mimic the unique sensing mechanisms of human skin. In addition, diverse functionalities in user-interactive, skinattachable, and ultrasensitive e-skins are introduced with the inspiration from unique architectures and functionalities, such as visual expression of stimuli, reversible adhesion, easy deformability, and camouflage, in biological skins of natural creatures. Furthermore, emerging wearable sensor systems using bioinspired e-skins for body motion tracking, healthcare monitoring, and prosthesis are described. Finally, several challenges that should be considered for the realization of next-generation skin electronics are discussed with recent outcomes for addressing these challenges.

“…There was also no obvious change in superoleophobicity and superhydrophilicity. The wearing resistance was also tested using an accelerated tribometer . The coated glass was placed facedown onto 240 mesh sandpaper; 3.2 kPa of pressure was then applied to the glass, and a reciprocating relative sliding with an amplitude of 10 cm was driven by the tribometer (Figure c).…”

Superoleophobic/superhydrophilic surfaces have incomparable advantages for oil-water separation and oil droplet manipulation; however, such surfaces are difficult to obtain on the basis of surface tension theory, and existing attempts are either not fully functional or are nondurable. Here, a solution to achieve the combination of superoleophobicity and superhydrophilicity by emphasizing the polar component of surface tension is proposed. The developed surfaces can be flexibly applied to almost any solid substrate and exhibit superoleophobic and instantaneous superhydrophilic property. The surfaces applied to certain substrates can be used for controllable oil transport, oil-water separation, and emulsion demulsification. Furthermore, a novel ferroconcrete-like structure to substantially increase the durability of the developed surfaces without affecting the superwettability is developed. The coated steel meshes preserve the ability of the material to separate oilwater mixtures even after over 400 m abrasion, which can be a significant step toward its widespread application.
