    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'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.

Compliant mechanisms look like the next scientific advancement. Truly amazing, sometimes we chemically design a new material that minimizes cost, and this time someone developed a mechanism that can minimize the amount of moving parts significantly reducing cost.
