Best of both worlds (LED technology)

People working under Professor John Rogers of the University of Illinois at Urbana-Champaign have managed to combine the robustness of inorganic LEDs (the kind we use so much here), with the physical flexibility of organic LEDs.They have devised a new mass-production method that allows large numbers of small LEDs to be picked up by a robotic arm and embedded into a wide variety of other surfaces, including glass and rubber.The LEDs are bright enough that they can be spread out far enough to be transparent, paving the way for displays built into windows.This is not new science, just new engineering. What would you do with it?BBC storyUniversity of IllinoisThe BBC picked the story up from Science magazine.

Flexible LEDs to boost biomedicine

Nature News is reporting today on the development of thin flexible sheets of LEDs which could be used for medical diagnostics, or even implanted in the body to use with light-activated drug delivery.  Besides these uses (obviously cooked up for the grant proposal :-) ), the clothing and other DIY uses seem fantastic! The interesting thing to me is that these sheets are made with conventional semiconductor LEDs (surface mount) and the flexibility of the leads is handled simply with extra lead lengths to pick up the slack. The original paper is being published in Nature Materials (Kim, R.-H. et al. Nature Mater. doi:10.1038/NMAT2879 (2010).

Looking for Heat Resistant Flexible Material

I am trying to find a heat resistant material that is flexible... I am trying to make a pull down shade to attach to a tension rod, that will make my home more energy efficient... This means It will also need to be thin enough to roll up into a small roll... It needs to be reflective or at least block out all the sun... I work nights and sleep through the day, and have trouble sleeping when the sun gets through...

Are there any inexpensive ways to make a material flex/contract when an electrical current is applied to it? Answered

I'm working on a small-scale prototype toy and it would be nice to have the ability to apply a charge to a piece of material and have it flex or contract. I kind of see it working a bit like a mechanical solenoid (and that is a possible option here although they would have to be tiny!) in that if the material looks like ____________ to begin with, when you apply a charge to it it becomes like __/\__ (excuse the poor ascii art!)

Flexible PCB rewiring

Hi,     I'm working on a project where I want to strip a 'roll up piano' down and take the rubber keyboard innards which feed into the electronic sound unit and get rid of the floppy rubber roll up piano keyboard and replace it with a standard PC qwerty keyboad. I got used to using a qwerty keyboard for playing tunes already and want tomake one that is stand alone that I don't need to connect to the PC to play music with. That means I need to take all the connections that you can see in the photos I uploaded and re connected each one to a key on the keyboard.  First of all, I don't know if pressing the rubber key on the roll up keyboad 'completes a circuit' and therefore prompts the electronic unit at the end of it to play the sound or if it 'breaks the circuit'. These units have two flexible pcb sheets as you an see in the second photo so when the rubber key is pressed they touch (although they all seem to be pretty much touching anyway). In an old casio solid keyboard I have there is a hard pcb and the piano keys touch a small rubber disk (much like is what under qwerty keys) to the pcb.   would it be better for me to take a razor and painstakingly slice up the flexible plastic which the pcb is printed on then lead them to the innards of the qwerty keyboard I'm going to modify or would it be better for me to just chop the flexible pcb off and use some kind of very thin coppe wire to feed dirctly into the unit and to the underside of the qwerty keys?   Any guidence would be appreciated.

Materials question? Answered

I know it is possible to by "flexible plywood" or "flexible MDF" - sheet material that can be rolled up in a single direction, whilst remaining rigid in the other. However, I have only found versions that roll with a minimum radius of about 15cm / 6". Does anybody know of a similar material that can be rolled with a much smaller minimum radius, say only 5cm / 2"? It doesn't have to be wood, any easily-worked sheet material will do if it can be rolled in one direction whilst remaining rigid in the other will do.

Anyone know a source for "GorrillaPod" type materials? Answered

I've been searching for a cost-effective source for "GorrillaPod" type parts.  Could be really helpful for many projects.  The closest things I'm able to find are http://www.modularhose.com    A bit expensive for many purposes. http://www.loc-line.com/              Seems like lengths are generally limited to 5.75 inch segments. Both of these products seem very good for what they are intended.  The loc-line looks like it can be joined - so maybe that is a good one. Is loc-line stiff enough to behave similar to gorillapod? It would be really nice if we could snap together pieces to make what ever lengths desired. Maybe this already exists and I've just missed it....

I recently got one of those 'LED shoelace' kits off eBay and I have use for the fiberoptic filament itself, not the LEDs and driver circuits. The filament is very flexible, somewhat rubbery in texture. I believe it's polyester or silicone. It's not a wonderful light conductor but it will work for my purposes. I have attached an image. The filament is the exact diameter of a T1 LED. Any help in finding this stuff would be most appreciated. Thanks!

Light(ish) and non flexible.

I am toying with the idea of putting together a non flexible notebook case. I really liked the look of my Timbuk2 sleeve and other sleeves out there, but they always leave out adequate support to prevent flex when in a messenger bag. I am pretty sure that being flexed across my back while cycling with a good amount of weight pressing on it killed the motherboard (twice!) on my old notebook and would like to avoid it again. I need some materials suggestions though. I need a non-flexible material to act as plates to be sewn into the outside covering of the case. Ceramic plate would be ideal, but the things that I have found are anti-ballistic and ridiculously expensive. Plate steel would work but it is heavy. Anyone out there with experience with plate steel or aluminum that can tell me how thin I can go without flex, or maybe some advice on materials that I haven't thought of?

Gluing PVC sheet: Can you identify 'this' glue? Answered

I am gluing black pvc sheet - I presume its pvc, although not 100% certain, it has that distinctive 'new beach ball' smell to it.  I'm prototyping right now, and I want to do more stuff like this - and will likely post an instructable - trouble is it walks a fine line of 'family friendly'/sfw. Either way; I used Lepage Flexible Plastic adhesive.  It worked quite well, and has proven to be quite strong and flexible so far...Works like a contact cement, but stays very flexible.  No mention on the packaging exactly what type of glue it is though.  My question:  What type of glue is this?  Characteristic acetone volatile smell, works like contact cement.  Package says apply, let dry to touch ~10-30 minutes then close surfaces.  I find it's dry to the touch within a minute or three. (extremely dry climate + warm room I was working in). Rationale:  It's expensive, 4 bucks for 30mL, and I'd rather have a can-container to dip a brush in.  At the hardware store they have plain-ol contact cement, but the transparent/flexible aspect of this is must. Thanks in advance!
