Mama always said you'd regret slouching one day, and while you've still got a few decades left before ultimately determining whether the sage-like advice was right or wrong, why take chances? The iPosture does the same thing as wearable posture reminders that we've seen in the past, but this one does so in a much more discrete fashion. The diminutive nano-sensor detects when your angle deviates just three degrees from the optimal position for greater than a minute, after which it emits a warning to straighten you out. Users insistent on keeping it crooked can turn the device off by powering it down, removing it or flinging it furiously into a wall. Life's next big nuisance will be shipping soon for $99.95.

Not like we haven't heard of at-home dialysis before, but a pair of researchers from UCLA and the Veterans Affairs Greater Los Angeles Healthcare System concocted a design which would make the process even more portable. The AWAK (automated, wearable artificial kidney) would "avoid the complications patients often suffer with traditional dialysis" by being bloodless in nature; additionally, it would theoretically "reduce or even eliminate protein loss." Fittingly, UCLA-VA has already inked an agreement with Singapore-based AWAK Technologies in order to develop a commercial version, but there's no mention of how soon the creators expect said device to be widely available.

Admit it: having a synthesizer in your pocket just isn't enough. No, you need one on your person in order to truly feel whole. If we just rang your bell, you should take a long, insightful look at the Square Band. The latest revision of the wearable synthesizer includes a volume control and a couple of flexible solar panels, the latter of which were added partly for aesthetics. Apparently wearers can simply trigger buttons tucked under their wrist with their fingertips, upon which a superabundance of cacophonic sounds will emerge and completely freak out any nearby bystanders. You have to have one now, don't you?

Those peeps at CuteCircuit, they of the SMS-sensing shirtsleeves, have come up with another wearable device of questionable practicality but definite coolness in the form of the Secret Message Glove. As its name suggests, the glove will let you pass messages secretly to another gloved individual with just a quick handshake, although we think they'll have to tone down the Michael Jackson-style design for more covert use. The glove was made as part of a workshop on smart textiles and physical computing but, sadly, plans for a DIY version don't seem to be available.

The last time we heard anything about the OnHand wrist PDA was probably close to two years ago. So, given its almost complete lack of marketing, distribution, buzz or sales, we're not exactly surprised that manufacturer Matsucom has decided to call it quits and stop producing the device, which managed to incorporate a full set of PDA functions into a fairly ugly watch. The OnHand was hobbled not just by a laissez-faire approach to marketing and a poor design, but by its use of proprietary technology and limited PC support (despite being introduced in 2003, it used a serial cable instead of USB). The small OnHand community did come up with some decent hacks, including a GPS hookup and an external keyboard, but that wasn't enough to keep this going. If you're still dying to get a wrist PDA, though, all hope isn't lost. Despite constant rumors of its death, Fossil's Palm-based Abacus wrist PDA is still available from TigerDirect for about $50.
