5 weird wearable technology products

So far, most wearable tech products are made to be worn on your wrist (as in smart watches and activity trackers) or, in at least one instance, perched on your nose (Google Glass). But judging by some new and pending projects we've come across, you could soon be wearing technology on your fingers, feet, and numerous other interesting places.

Nod Gesture Control Ring

This "universal controller" device, expected to ship this fall, fits around your finger (with the thicker part next to your palm) and lets you control various types of smart devices—phones and tablets running iOS or Android, computers running Mac OS X or Windows, Bluetooth/Wi-Fi-enabled bulbs, Nest thermostats, and more—by using natural gestures. You can preorder the ring now for $149.

Sensoria Fitness Socks

Here's one way to keep your wearable tech underfoot: The Sensoria Fitness Socks count your steps and track speed, calories, altitude, distance, and more. Also check out the Sensoria Fitness Sports Bra and Fitness T-Shirt with heart-rate monitors that let you track your performance. Each product costs $150; the socks ship this summer.

Misfit Bloom Necklace

This pretty pendant ($80), which ships May 16, is built to contain the Misfit Shine activity and sleep monitor ($100), which tracks walking, running, swimming, and other activities, as well as deep and light sleep. (The monitor can also be worn in a wristband.)

ElectroZyme Temporary Tattoo Biosensors

They aren't really tattoos but are more like a thin, flexible electronic sticker that contains biosensors. When the "tattoo" is applied to skin, these sensors analyze the wearer's sweat to determine fitness level, physical performance, electrolyte balance, and hydration level and see how effective the wearer's athletic performance is over time. They're not yet available for sale.

Smart PJs

These kids' pajamas look pretty normal—except for the unusual print, which is actually a series of QR codes. When you scan one with a smart phone or tablet, a bedtime story appears that you can read or listen to. They come in girls' or boys' sizes, $30 a pair.
