About a decade ago, NXP introduced its first generation Near Field Magnetic Induction (NFMI) radio, to help connecting hearing impaired persons with the digital world. Today, besides medical applications, NFMI is also being used in consumer devices to reduce power consumption and not be affected by body tissue absorption. NXP NFMI allows for hearable and wearable devices that can fit inside an ear canal or be worn on the body. Power levels are low enough to run for a week on a single ZnAir battery. Applications include truly wireless earbuds, implantable electronics, body area networks, under water communication devices, and many other low power.
