Miniaturization lets you create amazing things. She also paid attention to gadgets and jewelry. Amazing products were born - “smart” jewelry.
Today, a beautiful pendant or an elegant bracelet can hide a USB flash drive or something more, designers have not bypassed rings, earrings and other jewelry.
Actually, you won't surprise anyone with a flash drive + pendant hybrid, such a combination has existed for ten years, if not more, and not only in spy films. Flash drives are embedded in bracelets, watches, key chains. But you can find more interesting options. For example, practically useless, but very beautiful options for “smart” jewelry, such as a bracelet with a screen over the entire surface (using the program installed on a smartphone, you can decorate it with new patterns every day), a necklace that can change color to suit your mood.
Of course, more useful are pendants, bracelets, hairpins or other jewelry with built-in buttons to alert the police about an attack on the owner of the gadget, fix the coordinates of this event.
Competing with smartwatches are jewelry that can notify the owner of messages and calls that have come to his smartphone, as well as jewelry with built-in sensors to improve the quality of life. Among the latter are a bracelet that tells you when to stop sunbathing, earrings to correct your posture and a multifunction bracelet that offers personalized advice on physical activity.
A separate line is worth highlighting the result of the "crossing" of jewelry and medical devices. Interesting concepts already exist in this category, for example, a ring for the timely, painless and inconspicuous administration of insulin.
You say that these are strange toys? Perhaps … But every day there are new options for smart jewelry and not all of them are completely useless. Of course, one cannot do without comical hybrids, but if all medical devices become beautiful, miniature and painless, then one will have to sincerely thank the inventors for this alone.
