Neck Relax Electrode Pads

Consumable electrode pads for wearable neck massagers. Engineered with low-profile PU and high-cohesion hydrogel to absorb cervical flexion shear forces and support host device payloads.

These cervical contour electrodes act as the physical and electrical interface between the human epidermis and wearable TENS/EMS neck massagers. Unlike standard wired pads, these substrates are deployed on the high-curvature anatomy of the cervical spine. The geometry is specifically die-cut to avoid the central spinous processes while anchoring directly onto the trapezius and splenius capitis muscles. We supply these custom hardware interfaces to B2B massager brands and OTC electronic therapy OEMs.

• Host Payload Anchorage 

  Modern neck massagers are wireless. The battery, PCBA, and casing are physically snapped directly onto the electrode pad. This introduces a constant vertical and lateral gravitational shear force on the hydrogel matrix. A standard gel formulation fractures internally under this weight. We titrate the carbomer cross-linking density to increase the cohesive strength of the hydrogel, allowing the consumable substrate to suspend a 50g to 80g hardware host without structural tearing or dermal separation. 

   

• Dynamic Edge-Lifting Control 

  The radius of the neck changes continuously during head rotation. Rigid electrodes fail to contour to this shifting topography, causing the outer edges to lift. When an edge lifts, the active conductive area shrinks, forcing the constant-current pulse generator to push the same mA load through a smaller footprint. This impedance mismatch causes sharp focal stinging. The highly conformable PU backing, combined with a 3.0N tack hydrogel, locks the edges flush against the moving tissue to maintain uniform current density. 

   

• Rivet Tear-Out Reinforcement

  Users detach the heavy host device by pulling it forcefully away from the neck. This concentrated pulling force often rips the metal snap rivet straight through the soft PU backing, destroying the electrode. During the lamination phase, a localized layer of high-tensile Tyvek is inserted specifically around the rivet puncture zone. This physical barrier distributes the mechanical extraction force outward across the substrate, preventing the hardware from tearing through the polymer film.

• Rotary Die-Cut Tooling : The external geometry must precisely match the OEM client's hardware casing footprint. We machine custom steel rotary anvils to match any proprietary host contour, maintaining a $\le$ 1mm edge overflow tolerance.

• Logistics Routing : Conductive printing and base lamination run through our China lines. Terminal hardware riveting, QA visual sorting, and retail pouching are executed at our Vietnam hub to manage supply chain disruptions and optimize global import tariffs.

• Systems : Assembly lines operate within audited ISO 13485:2016 frameworks. 

• Biocompatibility: Raw material batches are documented against ISO 10993-5 and ISO 10993-10 limits.

Wearable hardware developers can request custom die-cut prototyping and vertical shear-force testing data.
