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:
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 about 3:44, you ask the question about how long the switch piece lasts. He referenced fatigue testing which got over a million cycles before failure. Is there any kind of metric or estimation to what that equates to in terms of time in real-world use? How long would that be expected to last?

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.
