Summary: The combination of skin stretch and kinesthetic information leads to better weight detection thresholds compared to presenting uni-sensory cues. Kinesthetic information is less reliable for lighter weights, while both sources are equally reliable for weights up to 300g. The presence of correlated noise might explain the discrepancy between an Optimal Integration model and the measurements for heavier weights.

Summary: The somatosensory system in humans allows quick identification and processing of sensory information, with skin as the largest sensory organ containing numerous receptors to transform stimuli into electrical signals. By simulating this human system, a flexible smart sensor system can be optimized for sensing and perceiving processes, reducing power consumption and improving speed.

Summary: A simple and effective vertical stacking sensor strategy was developed for high-performance dual-parameter sensing systems, which can detect and distinguish pressure and temperature. The sensor exhibits good performance in terms of sensitivity, response time, detection range, and stability, and can distinguish between pressure and temperature inputs without signal decoupling.

Summary: We have developed a simple and effective vertical stacking of sensing components strategy for high-performance dual-parameter sensing systems that can detect pressure and temperature. The dual-parameter sensor exhibits good sensing performance and can distinguish between pressure and temperature inputs. The preparation of the sensor is simple and low cost, and it has low requirements for the readout device.

Summary: This study explores users' tactile sensitivity and perceptual thresholds in a virtual environment by utilizing electrovibration tactile feedback and generating tactile stimuli with different waveform, frequency, and amplitude characteristics through two psychophysical experiments. The significance and potential of studying tactile perceptual thresholds can lead to improved haptic experiences in VR applications.

Summary: The study investigates the threshold changes of different nerve fibers (A beta, A delta, and C) due to somatosensory stimulation. Non-noxious stimulation showed a significant increase only in A beta fibers, while noxious stimulation increased pain thresholds in both A delta and C fibers and sensory thresholds in A beta fibers. These findings suggest that nociceptive inputs selectively suppress nociceptive stimuli.

Summary: This study assessed the benefit of a once-daily serum containing Adenosine, Magnesium Sulfate, Vitamin C Glucoside, and pre-and probiotic fractions in subjects with sensitive scalp. The results showed that the serum significantly improved global discomfort and sensitive scalp symptoms, reduced oxidative stress, and received high satisfaction from the subjects.

Summary: Tactual encoding of information is important for communication, especially for individuals with visual impairments. While Braille is widely used for text transcription, effective use of tactile graphics to communicate spatial or graphical information is lacking standardization. This study investigated tribology and perception aspects to identify key surface parameters. Results showed that modifying pattern pitch improved perception ability, but ridge width had a negative effect. Perceptive ability was closely related to the number of pattern ridges in contact with the fingertip during tactile graphic exploration, rather than friction mechanisms.

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: The purpose of this study was to evaluate regional differences in cutaneous warmth and hotness thresholds in response to radiant heat exposure. Measurements were taken on 17 body regions, and it was found that the forehead, lower back, and palm had the highest warmth thresholds, while the foot and sole had the lowest values. It was also observed that thermal thresholds from radiant heat exposure were lower than those from conductive heat exposure.
