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").
