Oh sure, we’ve seen gadgets used as motivational tools before, but Sega Toys is apparently banking on you not being a hothead. Otherwise, you just might fling its Body Trainer headset from your dome as soon as you hear “please exercise a little bit harder” over your incessant panting. Nevertheless, those with oodles of self-control may actually benefit from having a personal trainer (of sorts) in their ear while working out, and by monitoring the wearer’s heartbeat via a sensor, it can blurt out messages at the appropriate time to help users through their session(s). Reportedly, this nifty exercise buddy is set to launch in Japan this April for ¥5,775 ($54), and while we’ve no idea if this thing is destined for US soil, we can definitely see it being used more so for its musical abilities and less for its steadfast encouragement.

Sega Toy’s new Body Trainer is a “medical entertainment” product, we kid you not, designed to guide you through your exercise regime. Taking account of your age, weight and so on, it advises you with spoken prompts along the lines of “Let’s start warming up.” It actually measures your heart rate with an earlobe clip, so it can tailor its advice and can even detect if you’re slacking— you wont get a crazed Army drill instructor-style insult from it though, just a wimpy “please exercise a little bit harder.”

With three modes for walking, jogging and aerobics, the device also accepts audio input from an MP3 player so you can jog along to your favorite tunes, or a recording of your most inspiring jody if you actually are a military type. Available in April for around $53. [Tech.co.uk and Dvice]

The default Aliph Jawbone Bluetooth headsets already look quite stylish for a Bluetooth headset, but these Yves Behar-created limited edition sets beat his originals by quite a bit. The white, brown and black headsets are smooth, unlike the pock-marked original design, and represent trash talk, sweet talk and dirty talk, respectively. We can’t quite make out what the picture for sweet talk is supposed to be, but the dirty and trash talk are obvious. If we didn’t already own a Jawbone for our in-the-car conversations, we’d nab one of these ASAP. [Fuse Project via Josh Spear via Yanko]

Finally someone has combined the two things we love most — Bluetooth headsets and microSD storage — into one, sweet package. Enter the Bluetrek Bizz, a marriage of seemingly disparate products that actually kind of makes sense. On the headset side, you get up to seven hours of talk time, ten days on standby, and a customizable color panel. When you crack it open, you’ve got direct USB 2.0 connectivity, as well as a slot for a microSD card up to 8GB. You can charge the headset directly from any USB port, thus making your efforts to keep it at the ready a little bit easier. The headset weighs around 10 grams, and is slated in sell for around £40 (or roughly $80). Check out the totally jazzed-up video after the break to see what it’s all about.

Human trials are about to begin on a new device that goes inside a woman’s body for up to four days, holding fresh IVF embryos in place like an artificial fallopian tube. Developed by Swiss company Anecova, the 5mm-long “silicon womb” is pierced with hundreds of 40-micron holes, the better to expose the embryos to the natural environment of the uterus, rather than having to be developed artificially in an incubator. Scientists hope this will improve the chances of successful pregnancy from in-vitro fertilization. [Anecova and New Scientist]

Get to sleep in the brightest conditions with the Lights Out Sleep Mask, which, according to weblog Cool Tools, helps you go dark almost anywhere.

I was stationed for a couple months in Qatar and am currently stationed in Kuwait. The mask is more effective and comfortable than the other ones I’ve worn. You can open your eyes no matter the time of day and think it’s the darkest time of night. It blocks the light most effectively due to the contour over the nose.

The author also says that the mask’s room for your eyes allows you to completely open your eyes, see nothing but black, and keeps your eyes from drying out. Add this one to our list of the best ways to sleep smarter and better. The mask will set you back $10 on Amazon.

Oakley’s Split Thump MP3 player sunglasses’ fashion offenses are too numerous to mention, and we’re not sure this is helping matters. According to the folks over at Tech Digest, the wrap-around music players will be getting a very special 500-piece, 1GB Jamiroquai edition, replete with purple and white camouflage design and two new remixes from the disco-aping singer’s 1993 album Emergency on Planet Earth. Grab your glasses, get out your floppy hat, slip on some Mickey Mouse gloves, and crack open a bottle of Vicks VapoRub — it’s time to party like you don’t know any better.

Oh sure, there’s a multitude of head-mounted cameras out there for devout lifebloggers to snap up and wear, but we’re guessing the world looks a bit different when you’re scaring everyone off while waltzing down the street. Granted, the Momenta necklace isn’t a whole lot more attractive, but at least it’s a touch less noticeable. This concept would reportedly capture anything and everything that happened in front of the wearer, and when it detects a sudden jump in heart rate, it’ll log everything that happened five minutes prior and continue rolling until you tell it to halt. Kind of freaky, sure, but capturing the faces of folks who see you wearing this thing for the first time would undoubtedly be worth the price of admission.
