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:
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)

Ever hear about work hardening? The material slowly hardens with each use, and over time will become so stiff and brittle that it eventually breaks. That is why machines that bend are no where near as durable as properly designed and lubricated conventional ones.

In the realm of machines like the ones they exhibit here, flexibility can be very bad in the wrong spots. Imagine if the nuclear containment thing was made of flimsy material instead of steel, it would bend and open that seal, and arm the weapon. Bad idea!

Maybe someone who knows this is nothing new. Notch flexure hinges have been around for many decades. Professor W. van der Hoek pioneered with design principles like that and published his first book about it in 1962. His successor was professor M.P. Koster.
