Smart Microcurrent Sleep Regulation Tool

Lightweight handheld tool (12.5 × 6.8 × 3.2 cm; 180 g) engineered for daily sleep rhythm support. Housing made from durable medical-grade ABS; electrode surfaces use skin-friendly silicone. Utilises safe, low-amperage microcurrent (0.1–0.5 mA) delivered through palm contact. Rechargeable 3.7 V / 800 mAh lithium-ion battery enables ~7 days of intermittent use per charge. Two core functions: Relaxation Mode (promotes parasympathetic dominance) and Excitation Mode (supports sympathetic engagement). Not a medical device; intended for wellness-focused adults managing everyday sleep variability. Relaxation Mode encourages vasodilation — users feel a gentle warmth in the palms within minutes, reflecting lowered sympathetic tone and improved readiness for rest. Excitation Mode elicits mild vasoconstriction and subtle cooling — correlating with sharper mental focus and reduced brain fog. These responses are rooted in established autonomic physiology and offer tangible indicators of nervous system engagement. The device is optimised for consistency: same placement, same duration (5–15 min), same outcome — building predictable, non-habit-forming routine. Suitable for use in bedrooms, home offices, hotel rooms or quiet corners of cafés. Its minimalist design avoids clinical connotations, making it socially acceptable for daytime use — whether resetting after lunch or preparing for an evening wind-down. Aligns with NHS-endorsed sleep hygiene principles by reinforcing behavioural cues (e.g., consistent pre-bed ritual) with gentle physiological reinforcement.
