A growing number of medical products are clearly being designed to be “connected.” In other words, the device may make an immediate measurement and provide the readings locally, but it may then store the information for subsequent transmission to another device or location. Typically the transmission medium has been of either a wired (Ethernet, phone modem) or wireless (Bluetooth, WiFi, etc.). However, a technology called Near Field Communication (NFC) is entering the medical market after first penetrating the smartphone market. NFC is related to radio-frequency identification (RFID) with the exception that NFC is designed for use by devices within close proximity to each other sensing electromagnetic fields via inductive coupling. NFC works in the 13.56-MHz radio frequency spectrum, using little power to communicate data over relatively small distances. While NFC has received much publicity recently for its potential use in smartphone financial and filesharing applications, its use in medical applications has been limited. TechInsights has done an analysis of the emergence of NFC in a document entitled Market Landscape – NFC Technology Related to Mobile Communications. In addition, we have had the opportunity to acquire and teardown a number of units, enabling a look inside the evolution of this technology for medical devices.
