Network of electronic devices assembled on a flexible support and communication method

A system, comprising:

• a flexible first layer;
• and
• first circuits fixed to the flexible first layer, wherein the first circuits are configured to communicate with each other using a mutual coupling without contact,
• wherein the mutual coupling without contact comprises magnetic coupling circuitry comprising:
• an antenna for each of the first circuits;
• a first line of ferromagnetic material having a first end and a second end, the first line of ferromagnetic material extending in or on the flexible first layer and being magnetically coupled to the antenna for each of the first circuits;
• and
• a second line of ferromagnetic material having a first end and a second end, the second line of ferromagnetic material extending in or on the flexible first layer;
• wherein the first end of the first line is magnetically coupled to the second end of the second line, and wherein the second end of the first line is magnetically coupled to the first end of the second line to form a closed magnetic loop circuit;
• a magnetic generator coupled between the second end of the first line and the first end of the second line, wherein said magnetic generator applies an AC signal at a first frequency to the first and second lines to supply power to the first circuits, said first circuits communicating with each other of the first and second lines using a second frequency different from the first frequency.
