Abstract

ZnTech is a bioelectric, compression-ready textile sleeve designed to protect fragile, aging skin and lower the incidence of skin tears on the forearm and hand. The sleeve provides gentle, distributed mechanical support while delivering microcurrent through its embedded systems to support skin integrity and microcirculatory health during daily living skills. Intended users include older adults in home and long-term care, dermatology and wound-care clinics, and caregivers needing a comfortable, wearable prevention device that can be placed on independently.

This device consists of nylon/polyester-based fibers infused with zinc for biocompatibility and antimicrobial properties, and has silver-plated conductive microthreads integrated throughout the device in a low-profile electrode path. Targets for core performance are stimulation current of 0.1–0.5mA pulsed microcurrent (1–10 Hz), uniform current density of ≤0.2mA/cm² at the skin-textile interface, electrode line resistance <50Ω over 25 cm, and optional mild compression of 15–25mmHg without pressure hotspots. Moisture management will incorporate wicking yarns and a hydrophilic liner to maintain a relatively dry microclimate (wicking rate ≥ 3mm/min; air permeability ≥ 200L/m²/s), while maintaining natural tactile feel and dexterity. Durability objectives are around 40 wash cycles with electrical resistance <10% change overall and durability against abrasions according to ASTM D4966. Materials and components in contact with skin will be assessed to ISO 10993 with electrical safety in accordance with IEC 60601-1 for low voltage electronics and leakage limits.

Design for manufacturing focuses on circular-knit construction for uniform compression mapping, heat-bonded or flat-lock seams to reduce shear, and an automated process for placing conductive paths with bar-tack strain relief. The estimate cost of goods per sleeve is $25–$35 (textiles $6–$10, conductors $2–$3, trims/packaging $1–$2, labor $6–$8, electronics pod $8–$12 when included), and expected retail pricing is $79–$119, supporting a sustainable margin and demonstrating clinical usability and safety.
