穿戴式装置从手腕与指环走向「头戴式」神经科技：以 EEG（脑电波）读取大脑电讯号，再用 AI 解析状态。例子包括 Elemind 以 350 美元头带侦测入睡/清醒并以「粉红噪音」引导更深睡眠；在 21 人的小型试验中，超过四分之三的人更快入睡。另有 Neurable 500 美元耳机以 EEG 追踪与专注相关的 β 波，回馈专注度并在长时间深度专注时提醒休息。

大型科技也在切入：Apple 于 2023 年申请可感测 EEG 的 AirPods 专利，并在 2025 年稍早公布让 Vision Pro 可透过脑波而非肢体动作控制的无障碍功能，使其可整合脑机介面（BCI）。新创 Cognixion 已为 Vision Pro 开发 AR 应用与头带，当前聚焦协助因麻痺造成言语障碍者恢复沟通，但也可想像未来扩展到游戏或「用意念打字」。

医疗与监管面则有 Flow Neuroscience：其以微弱直流刺激（tDCS）搭配 App 行为治疗，于 2025 年 12 月获美国 FDA 核准，成为首款可在家使用、治疗重度忧郁症的非药物装置；并已在英国、欧洲、澳洲等地核准。临床试验 174 人显示 10 周缓解率 45% 对照假装置组 22%，预计 2026 年春季在美国上市。文末同时强调：可穿戴装置尚无法读出「私密想法」，但脑波资料高度敏感，将带来储存、保护与滥用（如广告或雇主监控）风险，且未来可能走向更隐形、无缝整合的形态。

Wearable tech is shifting from wrists and rings to head-worn neurodevices that use EEG brain signals plus AI. Elemind sells a $350 headband that detects sleep vs wake and plays “pink noise” to encourage deeper delta-wave sleep; in a small trial of 21 people, more than three-quarters fell asleep faster. Neurable markets $500 EEG headphones that track focus-related beta waves, report concentration patterns, and nudge breaks after sustained focus.

Apple is moving toward brain-based interfaces too: it filed a 2023 patent for EEG-sensing AirPods and, earlier in 2025, announced an accessibility feature enabling Vision Pro control via brain waves rather than physical movement, allowing integration with brain-computer interfaces (BCIs). Startup Cognixion is already building a Vision Pro AR app and custom headband, initially targeting communication restoration for people with paralysis-related speech impairments, with clear consumer spillovers like gaming or hands-free texting.

Medical-grade wearables are also emerging. Flow Neuroscience’s tDCS headset plus app-based therapy won US FDA approval in December 2025 as the first at-home, non-drug treatment for major depressive disorder; it’s also approved in the UK/Europe/Australia. In a 174-person trial, remission at 10 weeks was 45% with Flow vs 22% with a sham device. Flow expects US availability in spring 2026, amid growing privacy concerns over highly personal brainwave data.
