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)

At 9:06 you present a clutch which is OK, but you avoid saying "centrifugal clutch." AND, you present it to your "physics girl," who likewise does not use the word "centrifugal." WTF is going on here? Rather than pretending that this is a new invention (thus insulting everyone who had a go-cart when he was a kid), you could have been honest and discussed its advantages/disadvantages with typical in-use clutches.

That mechanism was good for force in one direction, the X direction. For an earthquake you would need to handle forces for Z and Y as well.

I didn't realize how massively important this was. I knew of its existence... I've seen it in application on various devices for various reasons, just never knew to tag a name to it, and never thought of it as a such a revolutionary way of making moving parts. In fact I've always feared it breaking more easily like the lid on your toothpaste (a very simple compliant mechanism we've all grown accustomed to without knowing it)

Can we not pretend that that plastic 'gripper' is in any regard better than a vice grip? That sort of stupid comparison makes it look like you;re full of shite when some of these advantages are very legitimate.

me papa's career revolves around this for jets. There becomes a point where no computer in the world can calculate those forces to a T but the principles remain the same - for practical purposes, even with an unlimited budget there are situations where knowledge of principle and experience of a lifetime of data an almost mystical intuition can be formed that can pick out flaws in computer models just by looking at them

While this is extremely interesting, these materials are bending like a paperclip. Everyone knows many materials can bend, just the right material and thickness will get you elastic deformation for the application you need. That's all this is but in a very cool configurations.
