  "main_findings": "A coplanar-coil based RF link design for communication between a programming wand and implantable medical devices was modeled, simulated, and tested. Experimental results were fairly consistent with simulations, and a typical circuit achieved a voltage transfer ratio up to 0.02, stated as sufficient to meet communication requirements.",

    "No RF frequency or exposure parameters reported in the abstract (e.g., frequency, power, SAR).",
    "No biological/health outcomes assessed; focus is on communication/link performance.",
    "No sample size or detailed experimental setup described in the abstract."
