MAGNETIC TECHNOLOGY Powerful. Affordable. Unique 3D capabilities

Operating principles

Based on magnetostatics principles (and not electromagnetism), ami’s technology consists of an array of tri-axis magnetic sensors measuring the magnetic field of at least one permanent magnet. Thanks to optimized and patented algorithms, these measurements allow to calculate in real time the 3D position & orientation of the magnet with a very high accuracy.

RF & touch interference-proof

As it is not based on electromagnetism, ami's technology cannot be affected by radio frequencies (RFID, NFC, BLE, WIFI, 5G.....). The ami technology is also compatible with existing touch surfaces and allows a transparent palm rejection.

Wireless charging interference-proof

Standardized components combined with ami intelligence

A permanent magnet as emitter

Our “simple magnet” emitter does not involve any electronics, hence may easily be embedded into everyday object, giving them a digital existence (a pen, a clutch pencil, a stylus ... a figurine, a joystick, a toy, a car...).

An array of standard sensors

Our technology is based on standardized low cost tri-axis magnetic sensors (less than 1mm3). Their number, position and type can be adapted according to the expected performances. Beyond design rules, ami’s engineering team may support you in all phases, from product design to sensor qualification, up to modelization.

Low computing power required

Since ami’s technology does not require powerful computing, it can be performed on an affordable IC. Cloud computing will also be an option in the near future. Processing is executed on an ARM Cortex M4F clocked at 180Mhz with 180k RAM & 256kb of flash memory.

Patented embedded Intelligence

Our patented algorithms are embedded in a secured IC. Thes algorithms allow different tasks:
- High accuracy real time 3D tracking
- Real time magnet orientation tracking (pitch & raw rotation)
- Magnet interference detection and compensation
