An apparatus (130) including an integrated circuit (200 200a) and at least one coupler (302a 302b) for electromagnetically coupling the integrated circuit (200 200a) to a conductor (323a 323b), which may be man-made or naturally occurring, such as in a human or non-human animal. The coupling is electromagnetic, i.e. indirect, and not a result of a mechanical attachment, but instead via an electromagnetic field (or only an electric or magnetic component). The conductor (323a 323b) may be suitable for conveying electronic or spintronic or optical signals, and the coupling is more specifically a coupling to the fields associated with such signals. The integrated circuit/chip (200 200a) can be electrical, optical, optoelectronic, or quantum, and can be of ordinary scale or nanoscale, and can make use of spintronic devices. A connector (100 100a) including such an apparatus (130) is also provided.
