Electrode Self Adhesive

Self-adhesive electrodes for TENS/EMS. Available in square, round, and rectangular profiles (e.g., 50x50mm, 50x90mm). Features carbon film and polyacrylamide hydrogel.

Self-adhesive electrodes are the primary hardware interfaces for transcutaneous electrical nerve stimulation (TENS) and neuromuscular electrical stimulation (NMES). The pads utilize a carbon film substrate coated with an ionic hydrogel to establish a reversible conductive bond with the epidermis. B2B clinical distributors utilize these consumables in physical therapy hardware deployments across various anatomical sites.

• Polyacrylamide Hydrogel Adhesion 

• Mechanical shear forces during patient movement dictate the failure rate of the pad. The polyacrylamide matrix is calibrated to a peel force of 3.0N - 5.0N. The cross-linking density restricts internal cohesive fracture, maintaining the polymer structure when peeling the pad away from the epidermis or the release liner.

   

• Carbon Film Current Dispersion

  High-impedance "hot spots" cause localized erythema, especially in smaller round configurations (e.g., Ø 25mm). The screen-printed carbon film functions as an electrical buffer between the metallic pin/snap and the gel layer. The carbon lattice disperses the electron flow laterally across the footprint, dropping the surface resistance below 50 Ohms. 

   

• Non-Woven Backing Stress Relief 

  Thermal insulation from thick backings accelerates gel desiccation. The 60g/m2 spunlace non-woven fabric allows passive vapor transmission. During dynamic joint flexion, the fabric accommodates mechanical strain without pulling the conductive film away from the underlying hydrogel.

• Supply Chain Routing: Base material die-cutting and carbon printing operate in our China facility. Final hydrogel lamination, connector assembly, and automated pouching are executed at our Vietnam hub for global tariff optimization. 

• Packaging Specs: 2 or 4 pads per PET/PE pouch depending on dimensions. Medical device brands utilize custom rotary printing on the pouch exterior and the PET release liner.

Quality Systems: Assembly lines audited to ISO 13485:2016 and MDSAP. .

Regulatory : Supported documentation for FDA 510(k), CE (MDR), and UKCA clearances.

QC Tracking: Batch-level log files record pre-lamination gel viscosity, 180-degree peel force limits, and DC impedance mapping.

B2B procurement teams can request standard dimension die-cut files and ISO compliance testing reports.
