Telecommunication – How NFMI facilitates a hearing aid system

The aim of this project was to develop a development application kit to demonstrate a hearing aid system composed of magnetic induction earplugs.


One of our clients had developed a single chip solution called NFMI (Near Field Magnetic Induction). This enables wireless streaming audio and data transfer using NFMI, a mature technology with proven results in the hearing aid industry. The NFMI technology boasts several important properties such as ultra-low energy consumption and the capacity to create an extremely reliable network in and around the human body, with audio and high-quality data transmission over short distances (<1m). An additional advantage of integration is that it requires very few external components. NFMI is a short-range technology and, as such, also creates a private network, which renders it much less sensitive to outside interference than 2.4 GHz.

The wireless headset contains two headphones: one earplug creates an NFMI network and the other joins the NFMI network.

ENGIBEX was responsible for the development of cards for the application development kit which enables functionality demonstration to consumers.
