    Compliant mechanisms have lots of advantages over traditional devices. SimpliSafe is awesome security. It's really effective, easy to use, and the price is great. Check out SimpliSafe here: simplisafe.com/veritasium
    I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:
    www.compliantmechanisms.byu.edu
    At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.
    What I learned about compliant mechanisms I summarize in the 8 P's of compliant mechanisms:
    1. Part count (reduced by having flexible parts instead of springs, hinges)
    2. Productions processes (many, new, different enabled by compliant designs)
    3. Price (reduced by fewer parts and different production processes)
    4. Precise Motion (no backlash, less wear, friction)
    5. Performance (no outgassing, doesn't require lubricant)
    6. Proportions (reduced through different production processes)
    7. Portability (lightweight due to simpler, reduced part count designs)
    8. Predictability (devices are reliable over a long period of time)

I was hoping you would have talked about metal fatigue. I mean plastic sure, but steel? What about inserting thread (carbon fiber) in the mold, kind of like rebar to give the metal even more strength at the bend point?

It's fascinating that "live hinges" which are typically maligned when creating moving mechanisms are becoming more and more acceptable. On the flip side, I've had such microscopic compliant mechanisms fail before (an accelerometer on a quadcopter), and fail in rather unpredictable fashion.

Bending is very handy for some mechanisms. I'd assume that tension and even the starting and resting point being dislodged could be an issue.. but I'm not an Aerospace engineer.... any you Egg heads got an opinion on it?

Serously, at 10:43 it looks like you are about to explain what is the matter with the mechanism at 1:19. But literally all you say is that the mechanism was miniaturized, then the hole is lined up with the laser beam and "all the crazy things happen from there". Where is the significance, what is the matter? Sorry, but in my mind, this is not "coming back to the device and explaining how it works", as you promised at 1:26. Please, if somebody reads this (highly unlikely, because of all te dumbf**k fanboys satisfied with mediocre explanations and praising this video and getting all the thumbs up for their needless comments), help me to understand what I am missing? I refuse to believe that I am the only person on Earth who thinks that there was no explanation whatsoever and hence there's no real purpose to this video, other than showing that interesting mechanisms exist.

At 1:19, you didn't understand how the mechanism is gonna keep a nuclear weapon safe, and neither did the viewer, sure. But by the end of the video, I still don't understand it, because you didn't explaint it even a bit. But of course, all the fanboys will still like and comment how awesome this video was. Am I stupid or something? Seriously, what the hell is going on? Somebody please help!

But how does this makes sence in a mass-production type setup? They will do 15.000 moves a day. It will be broken after the first week and you have to replace the whole thing. The 'normal' ones last decades with small to no repairs.

I'm no engineer; I just kept thinking about fatigue. Is that something that can be handled predictably, in how the materials are produced? (i.e. the type of plastic or metal, the curing/forging process, etc). It just seems to me that all that flexing is going to wear things out eventually (although, perhaps the whole point is that "eventually" is a much longer time than it would be in a similar device produced with multiple parts). Regardless, that is mind-blowingly awesome. I'll bet we'll be seeing more and more of this sort of thing in all sorts of products.
