Ekahau’s T301W Wi-Fi Bracelet will tell you exactly where the person is who is wearing it. And it doesn’t use GPS. Instead it uses Wi-Fi. But the T301W only works on preconfigured Wi-Fi networks that are coupled with additional beacons. Basically you build your own Wi-Fi triangulation network in a small area.

That may not be the best option for you, but it’s a neat idea. For $60 you get a waterproof wristband that operates up to a month between recharges. Hospitals can track patients, family members can locate one another at an amusement park etc.

The Bluetooth bracelet is designed to be worn on your wrist. When your pal calls your phone it vibrates to alert you of the incoming call. This is handy, say, if your phone is tucked away in a travel bag or if you have left it somewhere.

An LCD display on the front shows who is calling and when your phone goes out of range it also lets you know that the link has been lost. It’s also a watch. Some other features include: LCD Display Caller ID (showing Caller’s name from your phone book / Caller number), Can be charged by laptop or home PC via the USB cable provided, or the bundled AC adapter, LCD Display Size: 22mm wide, Bluetooth Spec: version: 1.2 – Compatible with V1.1, V1.2 & V2, Bluetooth Profiles: supported Headset and Hands free profile, Frequency range: 2.4GHz, Stand-by time: 100 hours.

This device is called the On Time Headset System, though it’s actually a bracelet that tells the time and handles all your incoming and outgoing phone calls. It will alert you to phone calls with rings and/or vibration. Vibration is good for quiet environments like the library.

The entire face of the On Time Headset System pops out as a wireless headset and when you use it as such, you still have a display since there is a secondary LCD display built-in. Both LCD displays would be touch enabled for ease-of-use. It’s a concept at the moment, but you can easily the benefits of wearing rather then carrying your phone.

Meet the dorkiest looking wrist accessory ever. You might think this is a cool cyberpunk bracelet thing. Actually, it’s the ultimate way to charge your batteries and look like a loser at the same time. If you don’t believe me, then by all means, check out the product site. There you can find pictures of people wearing and using this device.

It’s sad that it looks like such a train-wreck, because it’s a convenient way to charge up all your gadgets on the go. It uses a rechargeable li-on battery and comes with 8 different types of power connectors that will work with major brand mobile phones, the PSP and Nintendo DS. To recharge the portable battery, it takes about 5 hours. When used as a direct power source, it’ll give you 3 hours of talk time or 8 hours on your MP3 player.

For those looking to be stylish while always having some extra memory around their wrist, Brando has released its new USB thumb drive with decorative crystals.

The pros: No one is going to want to steal this tacky crapped up wrist-hugger with jeweled glass bits, so your data should be safe. Cheap crap should be in again this season. The cons: You’ve got a crappy piece of jewelry and already have plenty of flash drives lying around. For $33 you could do much better and probably get 3 rows of crap “Jewels” instead of 2. It’s available in silver or gold colors and the drive supports USB 2.0, Microsoft Windows XP/Vista, MAC OS and Linux OS.

Here’s a followup to the iPod Touch Nano concept that’s wearable and even fashionable. Once again, it’s from designer Isamu Sanada. It’s an iPod Shuffle Bracelet with integrated Bluetooth connectivity, dock connector, and a rugged casing.

It even sports a built-in rechargeable battery for 16-hours of continuous playback. Hey, why not? As long as we are playing make believe. This is actually something that the ladies would love, in fashionable pastels. Who knows, one day Apple may get behind it. But we aren’t holding our breath.

This concept security bracelet for kids comes from a project led by Rodrigo Torres. The idea is that if you combine a security bracelet with LEGO, kids will be more apt to wear it and be tracked for safety reasons. It’s got several features that will get your kid to keep it with him/her.

First off, they can design it the way they like with LEGO bricks. Throw in some games, photos, speaker and the a Lego man in front, and your kid is suckered into being tracked while having a fun device of their own. Heck, I want one myself. I don’t care if it’s tracking me. Sadly, it remains but a concept at the moment.

The iPod pretty much owns the day in the world of MP3 players, but that doesn’t mean they can’t give it a drastic upgrade in the future. Designer Gopinath Prasana prefers a wearable player and so created the iBangle concept. Wearing it is better then carrying an extra gadget after all.

This MP3 player is in the form of a bracelet or bangle, hence the name. It features a multi-touch track pad so you can control your playlist. It’s pretty small, so you won’t be watching videos or movies, making this like the iPod shuffle. Since everyone has different wrist sizes, the iBangle adjusts by inflating a cushion so it will fit snugly.

The Flux PC concept is one possible evolution of today’s portable computing systems. The PC becomes a whole new entity as the input and storage devices are more compact, adaptable and…Wearable .

A wearable bracelet acts as a hub for this new system. It interfaces wirelessly with a portable display and holds the users digital information while the display is used for a larger viewing area and multimedia devices. The display is used in those instances when larger viewing and interfacing is needed. The system can interface wirelessly with a portable display as well as other computers. This touch screen display is made with environmentally friendly materials. The bracelet itself would be highly customizable.
