IPhone12 will stop your implantable defibrillator

iPhone 12 and 12 Pro

In a recent paper in the journal Heart Rhythm, doctors describe how they turned off the potentially life-saving cardiac defibrillator function of an implanted Medtronic device simply by holding an iPhone 12 near it. The authors had nothing personal against Medtronic, or for that matter, against the new iPhone. The main reason they singled the phone out here was because it is compatible with some of the most advanced new technologies available for various magnetic-based communications and charging.

This technology, known as MagSafe, is basically harmless. It typically integrates charger, magnetometer and NFC reader into a compact package that depends on fairly decent alignment for efficient operation. The problem, at least for Medtronic, is the magnets that facilitate the positioning and docking. The iPhone 12, for example, has a ring of them around its central charging coil. In a nutshell, permanent magnets are never going away, they are simply a perfect solution to many gadget problems. Applications including securing cochlear implant links, joining cables and fastening wristbands now make extensive of use of strong, miniature magnets.
