Present day implants?

As you know, some girls wear them, but I think this technology would evolve with time. What would you use in cyberpunk/shadowrun instead of the current technology? And how would you set essence / humanity costs for such implants?

Using smart materials for changes in size / shape is a likely change, probably some hidden compartments as well. In fact they can install a lot of things in this implant. And for essence / humanity loss? I would say, it depends on options.

I would say the trend will be a bit more natural versions. At pregnacy, and in teen years some hormones control how big the breasts of a girl will be. Now imagine a small patch that releases some chemicals and cloned cells that help the breasts to grow. No cuts, no visible side effects, etc. Later they can make the patches smarter (they can react to changes in your body) or can use genetic engineering, etc. for more advanced adjustments. Next time, it will be a single injection with "smart" bacteria and cell samples. Who wants to wear a patch for ages when they can have this?
