• Symmetrical Planar Current Redistribution (3.5 × 10^7S/m Rolled Foil Web Suppressing Focal Current Crowding)

  Thaum monopolar radiofrequency tam sim no rov qab los ntawm cov dav hlau phais sib sib zog nqus, nws nkag mus rau hauv cov hluav taws xob hydrogel ntawm qhov sib txawv qhov xwm txheej. Nyob rau hauv nyias vapor- deposits metallized films (<10 um), the electrical sheet resistance of the thin conductor is high, creating a localized potential barrier that forces incoming current to discharge through the narrow perimeter edge nearest the surgical site. This boundary bottleneck produces thermal hotspots exceeding the 6.0C safety threshold. We eliminate this failure mode by utilizing a 38 um thick, high-purity (99.5% Al) rolled aluminum foil web exhibiting a bulk electrical conductivity exceeding 3.5 × 10^7 S/m. The high lateral electrical and thermal conductivity of the heavy-gauge rolled metal structure forms an equipotential plane: incoming RF current spreads instantly outward across the full X-Y footprint of the foil. Average current density across the 132 cm2 hydrogel contact area remains below 60 mA/cm2 under full-power cutting modes, distributing ther

• Tsis yog-Polar Hydrophobic Fluorinated Acrylic Foob (Hloov lub kaum sab xis θ> 105℃Halting Electrolyte Track Tsim nyob rau hauv cov kua dej)

  Continuous fluid irrigation during surgical resection procedures presents a severe failure risk: saline and blood wicking under the return plate create conductive bypass routes, causing current to divert toward grounded metal fixtures on the operating table. Standard medical adhesives formulated with hydrophilic tackifiers swell and lose cohesive strength upon water contact, accelerating this fluid path formation. We construct our perimeter seal from a crosslinked, non-polar fluorinated pure acrylic adhesive applied onto a 1.0 mm closed-cell polyethylene foam carrier. The cured adhesive surface delivers a deionized water contact angle exceeding 105 degrees, actively repelling aqueous solutions through interfacial surface energy mismatches. The closed-cell PE foam backing provides an impermeable elastic seal, resisting fluid penetration under hydraulic pressures up to 15 kPa. The adhesive perimeter retains a continuous peel bond (>5.5N / 25mm) mus txog 8 teev ntawm kev sib txuas ntxiv ntsev, tiv thaiv cov dej nkag, ntug nqa, thiab tsis muaj kev cuam tshuam tam sim no.
