ElectroCalm: Investigating User Experience and Physiological Responses to Multi-Node Transcutaneous Electrical Stimulation for Stress Modulation
依据摘要，Shon 与 Paredes 将 8 节点经皮电刺激阵列分别置于颈部与手臂，在认知负荷较高的 2-back 任务中考察用户体验与生理反应。可用性研究中两个部位舒适度相当且未干扰任务表现，但同一刺激在两处被解读不同；在电极贴附条件相同的主动与不主动刺激对比中，仅颈部刺激出现与压力调节一致的皮层和自主神经变化，手臂刺激与不主动条件无差异。
arXiv:2610.22748v2 Announce Type: replace Abstract: Transcutaneous Electrical Stimulation (TES) for stress modulation has largely focused on vagus nerve stimulation at the neck, yet two questions remain underexplored: how users experience electrotactile sensations at this sensitive site, and whether electrotactile feedback itself can function as a haptic stress intervention. To investigate this gap, we applied an 8-node TES array to two body sites during a cognitively demanding 2-back task: the neck, a site used in prior vagal TES research for its anatomical proximity to the cervical vagus nerve, and the arm, the most common haptic wearable site, which primarily provides cutaneous electrotactile sensation without vagal access. In a usability study, both sites were rated as comparably comfortable without disrupting task performance, though the same stimulation was interpreted differently across sites. A second study assessing the physiological effects of active versus inactive stimulation under identical electrode attachment revealed that only neck TES produced cortical and autonomic changes consistent with stress modulation, while arm TES did not differ from inactive conditions. These findings suggest that neck TES can be acceptable despite the site's sensitivity, and that both the physiological effects and the sensory experience of TES depend on placement.
