Those aren't integrated in watches, jewelry or clothing, as Kurzweil suggested. In fact the whole trend around wearable devices never really seemed to reach a sophistication necessary for the mass market, just like 3D printed clothing. So far we've got Google Glass which disappeared as quickly as it arrived, smartwatches that were mostly a question of time, and some fitness products like those running shoes with Bluetooth. But the actually challenging, futuristic part is still more a topic for blog articles in the maker community than a serious product category.

Even with those insulin devices the biggest innovations were made by some of its users themselves as far as I'm aware(see "looping").

That’s a marvel which is ubiquitous in developed counties. However, there’s been too much hype around the wearables. Manufactures have foreseen that progress in smartphones will inevitably stall and promised wearables as the next big thing. And, as it turns out, “smart watch” is still dumb as hell, at least when it comes to health.
