Summary: Shortly after touching an object, humans can perceive the sudden changes in the friction of the surface. The perception is robust only when the friction coefficient is reduced. This change in frictional properties during initial contact is interpreted as a normal displacement of the surface, which could enable the development of haptic surfaces that create illusions of interacting with mechanical buttons.

Summary: This paper studies the relationship between fractal surfaces and tactile perception. A multimodal tactile experiment was conducted using an EEG-fNIRS simultaneous joint imaging platform. The results show that fractal surfaces can be characterized by MFCC, sample entropy, and permutation entropy, and these three samples also have different brain functional reflections from fNIRS results.

Summary: Measuring the friction between human skin and textiles is crucial for preventing skin-related health problems and discomfort. This study used a portable friction measuring device to evaluate the repeatability of friction coefficient measurements and tactile perceptions at various body regions. The results showed that the friction coefficient and tactile perception differed significantly across different body regions.

Summary: The study shows that conscious perception of frictional information requires a sufficiently large lateral movement, as moderate tangential forces alone are not enough to perceive frictional differences. These findings may be useful in designing haptic devices based on friction modulation principles.

Summary: By studying mice, it is found that sensory neurons labeled by Mrgprb4 are able to detect mechanical stimulation and play a crucial role in sexual receptivity and dopamine release. Optogenetic stimulation of these neurons can induce a conditioned place preference and a copulatory posture even in social isolation. In the absence of Mrgprb4-lineage neurons, female mice no longer find male mounts rewarding and show aggression instead.

Summary: The research investigates the normalization of finger pad friction data to correlate between individuals, allowing for the discussion of data with respect to other variables. The study demonstrates the elimination of unknown parameters by using a reference smooth sample to normalize the dataset.

Summary: This article discusses the challenges in touch neuroscience research and compares it to vision science. The lack of naturalistic stimuli, especially in social touch research, has hindered progress. However, new methods and recent successes offer hope for overcoming these obstacles.

Summary: Soft sensors capable of differentiating shear and normal force can enhance machines' control in physical interactions with humans. The capacitive sensor, composed of patterned elastomer, distinguishes between normal force and shear using signal summation and differences. With low crosstalk and high sensitivity, this sensor shows potential for application in humanoid robotics.

Summary: Individual differences in skin stiffness modulate the mechanical signaling of touch and shape individual differences in perceptual acuity. Softer skin can better discriminate compliant objects and generate more prominent patterns of deformation.

Summary: Human perception of touch is influenced by inputs from multiple channels. Contrary to classical theories, it was found that inputs from two sub-modalities of mechanical input channels interact to determine tactile perception. Sustained mechanical pressure was shown to inhibit tingling sensations induced by a bioactive compound, without mediation from nociceptive or affective channels.

Summary: A full-skin bionic electronic skin driven by artificial intelligence (AI) is proposed, which exhibits high sensitivity and fast response/recovery time. It can evolve from tactile perception to intelligent tactile cognition, and can achieve real-time cognition of object material species and locations via one contact. It has broad application prospects.

Summary: Two studies were conducted to examine the influence of names on object touch. Negative-named objects were touched for shorter durations and rated more negatively, while positive-named objects were touched for longer durations and rated more positively, similar to chemosensory verbal context effects.

Summary: This study utilized a multimodal method to investigate tactile perception, analyzing the surface properties of different grit sandpapers, conducting psychophysical experiments, and measuring mechanical parameters and EEG simultaneously to observe the entire tactile loop. The results showed that the 600-mesh sandpaper had the largest characteristics and significant differences and correlations between 3000- and 600-mesh sandpaper in various aspects.

Summary: Through experiments involving slip events on a fixed fingerpad, researchers found that tactile afferents respond quickly and sensitively to slip events, with FA-I afferents in particular faithfully encoding compressive strain rates resulting from those slips. Due to the high density of FA-I afferents in fingerpads, they are well-suited to detect incipient slips and provide essential information for grip force control during dexterous object manipulation.

Summary: Research has shown that finger skin deformations during active object manipulation encode behaviorally relevant information to the central nervous system. Monitoring finger skin responses in an active setup can help identify aspects of deformations relevant to online control. A novel device has been developed to monitor finger forces, skin deformations, and kinematics during fine manipulation, showing a direct influence of grip force on fingerpad skin strains.

Summary: In this study, the influence of gravity on isometric force control was examined. It was found that gravity creates an illusion that upward forces are larger than downward forces of the same magnitude. Additionally, gravity also affects the control of grip force. These findings have implications for the design of haptic devices to be used during flight or space activities.

Summary: Research shows that surface skin deformation during partial slippage at finger-object interfaces triggers firing of tactile sensory afferents. This study investigates the dynamics of surface skin under purely torsional forces on the finger pad, revealing that partial slips develop from the periphery towards the center and result in surface strains. The findings also demonstrate the effects of normal forces and angular velocities on torque, strains, and the twist angle required for full slip.
