Can wearable devices operate and get charged with no physical charging port? When talking about port-free charging, Qi wireless charging may be your first thought. However, compact wearables such as smart rings and miniature TWS earbuds have long faced constraints. Limited internal PCB space makes them poorly suited for traditional Qi solutions. Meanwhile, exposed physical charging interfaces suffer from corrosion and poor long-term durability.
To meet demands for ultra-compact layout, together with waterproof, dustproof and anti-corrosion performance, NFC Wireless Charging (NFC-WLC) provides a practical alternative. Built upon the 13.56 MHz NFC standard, energy is transferred wirelessly via inductive coupling. There are no spring contact pins or exposed metal ports. Hardware designers gain greater flexibility to implement streamlined enclosures with reliable waterproof and dustproof capability.
