The cool thing about cyborgs is that they have abilities beyond that of the native human—similarly, this ear can do things mine can’t. For a start, the researchers printed an antenna in the ear that has significant sensitivity to microwaves. This is actually a very impressive achievement, because the entire electronic circuit was printed using polymer gels (the conductive parts were silicone doped with silver nanoparticles), which generally don’t cope well with radio frequency currents.
In principle, with a bit of extra electronics, the cochlea implant would allow a human to hear radio, TV, Wi-Fi, microwave ovens, airport radar systems, and various other electromagnetic signals (much like a satellite finder). This sounds kind of cool on one level, but you would really want to be able to turn it off. Imagine trying to go to sleep to the sound of your Wi-Fi arguing with the neighbor’s about who gets channel one.
