Power Scavenging 2.0

A few months ago (has it really been that long?) I posted the story about the Australians kicking off a new initiative for a power-scavenging shirt at CSIRO (that post can be found here). In that post a mentioned (and linked to) a group of guys who are working at the nanoscale to achieve the energy harvesting. And while it was certainly impressive, they were only able to scavenge at ultrasonic harmonics (not mechanical) -- well guess what? They've now developed a methodology to grow the scavenging nanowires on the surface or polymeric fibers and can harvest mechanical energy. The group's homepage can be found here, I would suggest reading through the previous papers first to get a sense of how they've progressed over the past few months.

They estimate that with this fibers integrated into a yarn, a square meter could yield roughly 80 mW -- granted this is assuming A LOT (the ability to make enough of this fiber affordably, the ability to make a yarn, and an interconnect scheme with low loss!) however it at least gives some vague parameters for developers on the other end to pull this through as it develops. Of course, the usual applications are mentioned: ipod shirt, biomedical applications, etc...but I feel like there are much cooler applications that can be explored, what do you think?

Surveillance Vest!

I love this post (saw it on gizmodo via Danger Room)-- it is the perfect snapshot of where we are in terms of technology for Interactive Textiles... (at least in the marketplace). May I present the surveillance vest!

Discrete electronic components with a honkin' big battery pack. I seem to recall someone at a SmartFabrics conference refer to this as the "textile as a container" methodology. I really think we can do better (flexible polymer-ion battery, fiber-optic mic, textile button interface -- ok, admittedly the camera is a bit harder). But in terms of its actual application you might as well be wearing this:

The gizmodo posting is good, the comments are better. The company's website can be found here. It is obvious that their strong-suit lies in the back-end and infrastructure rather than the sensors and packaging -- but if the iphone and ipod has taught us anything it is that design and packaging equal adoption.

I've also read a good blog on why the spider-suit idea is dead in the water...I'll address that in the coming days...

Fashion and Interactive Textiles

To be cool is to be fashionable. It seems that these days technology and fashion are starting to merge -- see Angel Chang and Elena Corchero. And while certainly not mainstream yet, you can see trends developing out of niches. But we don't typically talk fashion here, other people do that much better than we do (see talk2myshirt.com or this blog entry) -- in fact I've taken my own jabs at it from time to time.

But I will say this, these types of efforts do push people to think in different ways about technology and how they interact with it. The fuel for most of these efforts is of course the emergence of the cell phone and the ipod -- all of a sudden there are technologies that people want with them at all times...since we have our clothes with us at all times (mostly), it seems like a great fit. But I don't think we're quite there yet (at least on the technology side). We have yet to get away from bulky processing and power (although Nantero and Konarka are making headway). We need textiles to "enhance" the technology, not hold it -- we can buy an elastic band for that or simply use a pocket. It's expensive to integrate the technology and thus its only available in high end items that can absorb the cost -- and with Eleksen's hiccup we may have seen that the business model isn't proving out for that route either.

So who do we look to? Who still researches this stuff? Check out these efforts in the US, and these companies/universities in Europe...

The OR Show recap

It was truly exciting and there was lots of technology to see -- unfortunately there was very little in the way of "interactive" textiles. There was a good deal of heating applications in apparel with a number of companies such as Mountain Hardwear, Outdoor Research hinting at using the technology as well as a handful of less-technical products that used the technology for novelty purposes.

But still no major technology insertions coming from the big companies...

So the question remains: Are interactive-textile technologies doomed to remain confined to SkyMall or will they actually find their way to be adopted by more established companies?

Winter OR Show

I am heading to the Winter OR Show this month (January 23rd - 25th in Salt Lake City) and I'm looking forward to seeing some new technologies hitting the market. Hopefully we'll see something beyond the standard "ipod" or "MP3 jacket" type of product.




This winter season is expected to have more interactive textiles than the summer show, but we'll have to wait and see. For a look back at the sparse "summer market" OR Show, visit my August review. Stay tuned...

"Did You Know..."

I realize this isn't necessarily about Interactive Textiles, but it is something worth looking at nonetheless.




Thanks to Winston for pointing it out (this is version 2.0 by the way)...
