ZnTech™ Technology

Microcurrent
Engineered Into Fabric

ZnTech™ is Ion Technologies’ proprietary elemental zinc technology — designed to generate continuous low-level microcurrent on skin contact, with no wires, no charging, and no external power source. Applied as embedded zinc in polyester yarn for textiles, and as zinc-particle coating on carrier materials for wound care.

Overview

Bioelectric Activation, Engineered Into Materials

ZnTech™ is built on a clear scientific premise. The body is bioelectric, and the skin is an active electrochemical environment. When the right material meets that environment, wear can become more than passive coverage — it can become a functional interface.

ZnTech™ uses the natural oxidation of elemental zinc. When exposed to skin, moisture, and oxygen, the zinc generates continuous low-level microcurrent at the surface — whether it is embedded in a polymer yarn worn against the skin, or coated onto a wound care dressing in contact with tissue. This creates a localized electric field at the skin interface, with applications relevant to performance, recovery, hygiene, and emerging therapeutic formats.

Core Mechanism

The Zinc-Oxygen Battery Effect

ZnTech™ leverages a fundamental bioelectric reaction. Elemental zinc — either embedded within polyester yarn for textile applications, or applied as zinc particles coated onto carrier materials for wound care — undergoes oxidation when exposed to moisture and oxygen at the skin surface. This oxidation reaction — the same principle governing a zinc-oxygen battery (Korall et al., US Patent 5,445,901) — generates electrochemical potential.

That potential drives continuous low-level microcurrent generation during wear. Measured voltage at the skin surface ranges from 0.17 to 0.6 volts, producing current delivery of 3-7 microamps, a range that mimics the body’s natural current of 2 to 10 microamps (Richter, 1929; Fish & Geddes, 2003).

No electronics. No battery pack. No charging cycle. A passive material response activated by normal wear conditions — particularly by moisture such as sweat.

No wires. No batteries. No device.

Architecture

Embedded, Not Applied

What differentiates ZnTech™ is how the elemental zinc is integrated into the material — and this differs purposefully between the two application formats.
For textiles, elemental zinc is embedded directly into polyester-based yarn during the yarn manufacturing process — forming the ZnTech™ yarn. This is not a coating applied to a finished fiber, not a surface print, and not a temporary treatment. The zinc is integral to the yarn structure itself. This is why the technology is designed to remain active through repeated use and laundering: the zinc is in the yarn, not on it.

For wound care, elemental zinc particles are coated onto existing carrier materials — such as collagen matrices, hydrocolloids, or other wound care substrates — using a proprietary process developed by Ion Technologies. The process is designed to achieve consistent, effective zinc distribution on the carrier surface, ensuring reliable microcurrent generation when the dressing contacts the wound environment. The carrier material itself is chosen for its clinical relevance to the wound type; the zinc coating adds the bioelectric layer without altering the carrier’s fundamental wound care properties.

In both formats, the active material is elemental zinc and the mechanism is the same: zinc oxidation in the presence of moisture and oxygen drives continuous low-level microcurrent at the skin surface. The material format is adapted to the application. The chemistry is consistent.

How It Works

A Three-Step Bioelectric System

STEP 1

Activation

Contact with skin, combined with moisture and oxygen present at the surface, initiates the electrochemical reaction in the elemental zinc. For textiles, this occurs across the ZnTech™ yarn in contact with skin; for wound care dressings, it occurs at the zinc-coated carrier surface in contact with the wound. In both cases, the skin or tissue acts as a conductive partner. The body becomes part of the circuit.

STEP 2

Microcurrent Generation

Zinc oxidation drives continuous low-level microcurrent during wear. The system is self-regulating — current output responds to the conductivity conditions at the skin surface, which vary with moisture level, heat, and skin resistance. This means current delivery naturally increases during exertion, when it is most relevant.

STEP 3

Skin Interface

The microcurrent creates a localized electric field at the skin surface. This field interacts with the body’s existing bioelectric environment — stimulating underlying tissue including nerves, blood vessels, sweat glands, and muscle (Bogie & Triolo, 2003; Pfeiffer, 1968). The result is a range of targeted physiological responses.

Functional Effects

The Bioelectric Effects of ZnTech™

Once activated on skin contact, ZnTech™ creates a microcurrent interface that drives observable effects at the skin surface and throughout the local wear environment. Each effect is grounded in documented mechanisms.

Enhanced Blood Flow & Circulation

Microcurrent stimulates capillary density, blood flow, and tissue oxygenation (Bogie & Triolo, 2003; Park et al., 2011). In thermography testing conducted by Integrated Pharma Services (August 2021), subjects wearing ZnTech™ patches showed measurably elevated skin temperature (+2–3°F) compared to control fabric over 1–3 hour wear periods — a validated indirect indicator of increased blood flow. Improved circulation supports oxygen and nutrient delivery to tissue, ATP synthesis in mitochondria, and elimination of metabolic waste products.

Reduced Moisture & Odor

The electrical current produced by ZnTech™ inhibits sweat gland activity — an effect well documented in hyperhidrosis treatments (Bolton et al., 1980; Sheftel clinical study). In a controlled left-foot/right-foot internal study, participants wearing the ZnTech™ sock on one foot and a standard sock on the other consistently reported significantly less sweating and odor on the ZnTech™ side.

Microbial and Fungal Protection

Low-level electrical current inhibits bacterial and fungal activity — the organisms responsible for foot odor, athlete’s foot, and skin infection (Bolton et al., 1980). In independent bacterial and fungal testing, ZnTech™ demonstrated significant inhibitory activity against relevant microbial targets.

Antiviral Activity

In two independent studies conducted by Integrated Pharma Services (August and September 2020) using ISO Standard 18184:2019 methodology, ZnTech™ fabric demonstrated viral protection activity against Influenza A (H1N1, H3N2), Human Coronavirus NL63, Human Coronavirus OC-43, and Feline Calicivirus. Reduction rates ranged from 92% to 99.99% across tested viruses. These are lab-context findings; clinical claims are not made.

Iontophoresis — Enhanced Absorption

The microcurrent generated by ZnTech™ demonstrates iontophoresis properties — the ability to drive ionic compounds through the skin barrier using electrical current. In IPS testing (November 2021), ZnTech™ showed positive absorption of a topical compound within 1 second of contact, while control fabric showed no transfer even after overnight incubation. This positions ZnTech™ as a potential delivery platform for pharmaceutical and cosmeceutical applications.

Collagen Stimulation & Tissue Repair

Microcurrent stimulation is associated with increased protein synthesis, enhanced collagen production, and support for wound healing at the tissue level (Cheng et al., 1982; Isseroff & Dahle, 2012; Singer & Clark, 1999). These effects extend the ZnTech™ platform’s relevance into dressings, patches, and therapeutic wound care formats.
