Article Abstract
Proprioception is essential for coordinating human movements and enhancing the performance of assistive robotic devices. Skin stretch feedback, which is used within natural proprioception mechanisms, presents a promising method for conveying proprioceptive information. To better understand the impact of interference on skin stretch perception and to provide insights into how to best balance between perception performance and the workload required for its understanding, we conducted a user study with 30 participants that evaluated the effect of two simultaneous skin stretches on the user's ability to perceive changes in skin stretch and the associated perceived workload. We observed that when participants experience simultaneous skin stretch stimuli, a masking effect occurs which deteriorates perception performance in the collocated skin stretch configurations without changing the perception of workload. These findings imply that multi-channel skin stretch designs should avoid locating modules in close proximity due to the lower sensitivity in perception.

Cortical somatosensory responses evoked by orofacial skin stretch experimentally applied during speech movement planning in stuttering and nonstuttering adults.

Prior findings indicate that individuals who stutter do not show the typical modulation of auditory processing that is observed during speech movement planning in nonstuttering speakers. We now ask whether this lack of planning-related sensory modulation in stuttering adults is specific to the auditory domain. In this first study (15 stuttering and 15 nonstuttering participants), we implemented the prior stimulation timeline in a paradigm with orofacial skin stretch stimuli.

Background: Ultrasound-assisted transdermal drug delivery, or sonophoresis, enhances skin permeability, offering a non-invasive alternative for drug administration. However, its clinical application remains limited because of an insufficient understanding of its underlying mechanisms and optimal parameters. This study investigates the factors influencing ultrasound-enhanced drug absorption and examines its biological effects on skin structures and HaCaT cells, providing a comprehensive analysis of its mechanisms.

Tactile sensing arrays play a crucial role in human-machine interaction, robotics, and artificial intelligence by enabling the perception of physical stimuli on robotic surfaces or human skin. However, skin-attachable sensor arrays still suffer from strain interference and signal crosstalk under stretching or bending, particularly on curved or deformable surfaces. Here, we present a stretchable tactile array that is both strain-insensitive and crosstalk-suppressed, achieved via a hierarchically segmented design that mitigates lateral and vertical deformations synergistically.

Desmoplakin (DP) is a key DSM protein which anchors plaque proteins to keratins, thereby ensuring tissue integrity under mechanical stress. Clinically, DP mutations impair keratinocyte adhesion and structural integrity, leading to skin fragility disorders.

Soft tissue manipulation is used widely to assess myofascial tissue qualitatively but lacks objective measures. To quantify the mobility of myofascial tissue, this effort derives optical biomarkers from the skin surface, as observed in the hands-on workflow of clinicians. Digital image correlation using three high-resolution cameras captures the cervicothoracic region as a clinician deeply engages and stretches the skin and myofascial tissue.
