“…One of the unique features of our study was the use of suction stimulation as the mechanical stimulus. By using the suction device developed in a previous report, 35,36 the skin deformation in response to mechanical stimuli was measured while assessing tactile perception. Furthermore, as the skin is not pushed in by using suction stimulation, the mechanical properties of the superficial skin layer can be observed rather than the properties of the muscles and fat in the deeper layers 37,38 .…”

Background The tactile perceptions arising on the skin mediate representations of the body and perceptions of the external physical world. Thus, these tactile sensations greatly impact our lives. Although tactile perception is caused by skin deformation, few studies have investigated the contribution of skin physical properties to tactile perception because the skin deformation in response to mechanical stimuli is difficult to measure in real time. In this study, we investigated how the skin deforms in response to externally applied mechanical stimuli and the effect of skin deformation on tactile perception. Materials and methods Tactile perception was assessed using psychophysical methods. A suction device was used to measure skin deformation in response to mechanical stimuli while assessing tactile perception. The relationship between skin deformation and tactile perception was investigated. Results Individuals show different skin deformation behavior in response to stimuli of the same intensity, and the amount of skin deformation affects the perceived pressure induced by suction stimulation. Furthermore, when the amount of skin deformation is small, tactile perception becomes more difficult, and the ease of tactile perception varies. Conclusion We argue that dynamic skin behavior is an important factor in tactile perception. Focusing on skin physical characteristics from a constructivist perspective of complex tactile perception may lead to improved tactile communication perception through the control of skin physical properties and realistic tactile presentation in remote environments.

“…The effect of hydration on tactile sensation depends on the participant's age and sex, 19 and even within an individual, the tactile sensation itself varies according to the stimulated site due to the complexity of skin tissue that exhibits markedly anisotropic and heterogeneous responses 20 . Therefore, we used a device that can measure skin deformation while simultaneously presenting tactile stimuli at the same site on the skin by suction 11,21,22 . This approach went beyond observing the compliance of the stratum corneum, allowing us to explore how it influenced the mechanism of tactile sensation.…”

BackgroundTactile sensation plays a crucial role in object manipulation, communication, and even emotional well‐being. It has been reported that the deformability of skin (also described as skin compliance) that shows a large mechanical response to stimuli is associated with high tactile sensitivity. However, although the compliance of the stratum corneum, the outermost layer of skin, can change daily due to skin care and environmental factors, few studies have quantified the effect of the stratum corneum on tactile sensation.AimsWe investigated the changes in tactile sensitivity resulting from skin hydration and identified corresponding alterations in the compliance of the stratum corneum.MethodsA randomized controlled trial was conducted. Participants were randomly assigned to an intervention group (n = 20) that had a moisturizing cream applied to their cheeks or a control group (n = 19) that had Milli‐Q water applied to their cheeks. Tactile discrimination performance was assessed using psychophysical techniques before and after application. The water content, mechanical response characteristics, and penetration of PEG/PPG‐17/4 dimethyl ether from the cream in the stratum corneum were evaluated to identify hydration effects. Skin deformations occurring during tactile sensation were measured concurrently using a suction device employed for tactile stimulation.ResultsTactile sensitivity was increased in participants who had cream applied to the skin surface, while no significant change was observed in participants who received Milli‐Q water. The improved discrimination of tactile stimulus intensity was directly related to the magnitude of skin displacement. The higher water content of the stratum corneum due to cream application decreased the dynamic modulus of elasticity of the stratum corneum and increased the skin's extensibility in response to tactile stimuli.ConclusionsHydrating the stratum corneum significantly enhances tactile sensitivity and is accompanied by an increase in skin extensibility, a factor in tactile intensity perception. The compliance of the thin stratum corneum layer plays a crucial role in tactile experiences that involve skin stretching.
