How electricity in your bones makes them stronger | Piezoelectric effect

A while ago I heard about something called the piezoelectric effect. I read a few articles and watched a few videos because I wanted to understand it and, here we are, a video with all my findings compiled. The piezoelectric effect describes a phenomenon where applying mechanical force to special materials results in electricity flowing through this material. In this video I describe the mechanism for the piezoelectric effect in an intuitive way and then describe the effects electricity has on bone growth (hint: it makes them grow). I also describe something I found extremely fascinating - how bones optimise their trabecular structure to maximise strength (for resistance to fractures) and minimise weight (for energy efficient movement). In engineering, this is called topology optimisation, and amazingly bones do a very similar thing!

Awesome info and beautifully said each and every detail 😊

[rvalasini]

I forgot to add... Can you please do a vid about cartlidge and all that stuff that cushions the body between the spine and also the Knees... the lubrication etc. How it all ties into the way the body heals and replenishes. Much appreciated.

[Kurbo]

Yooo how do you only have 76 subscribers? You talk about really cool stuff and your videos are high quality!

[harrisashraff]

Such a really cool video. I am a coach as well as an engineer and I understand the importance Piezoelectric effect, especially for tendon and soft tissue training with my athletes. Thanks for the very nice explaination.

[rvalasini]

Yes!!!! Now this is what I want to see more of.

OMG, this was so useful, I'm in highschool and only recently learned about piezoelectric eff in chemistry related to solid crystal structures...n i was wondering if it would be related to bones and when I searched ..there was a LOT of material which I was not expecting to find about it! N rn I'm skipping my online test to watch this vdo 😂

[bingoyes]

OMG! He jus stands and simply talks and i didnt lose focus AT ALL!

285hz tuning fork frequency is used to read and heal bones.

Contact care flinchlock release has covered this for 20 years in NZ

Makes a lot of sense in this electric universe.

Thank you for such interesting video. ‎
However, some factual corrections are needed.‎

At time (0:14), the following correction is needed. :…….charges will be displaced ‎and an electric field is setup as no current flows till wires close the circuit; a fact ‎you mention after that.‎
The same correction applies at time (1:24).‎

Have you read the body electric by Robert o becker?

[RomaWatkinsMain]

This is fascinating, what discipline of science/medicine would you say this type of knowledge falls under?

[abbyx]

Do you have a source for the topology optimization portion?:)

[SunilYadav-thwb]

How can this guy be so under rated.. YouTube algorithm you suck

[tmfd]

Can you use an outside source of electricity to stimulate the osteoblasts, since piezoelectric works both ways?

[abhinav.verified]

Curious doc wonder what do you think about how this affects hibernating mammals?

[erozi]

Didn’t explain how exactly the piezo effect induces change in the trabecular bone

[genkiferal]

Whew! A scientist in a longevity/Calorie Restriction group made a comment that my bones must be too porous or weak because of my low BMI. I was beginning to worry. Stronger ***AND*** lighter? yes!

We are electro-magnetic just as much as we are physical. I think there are many more “invisible” phenomenon that our bodies are involved with which we don’t understand.

I’ve read about evidence of cells being connected to each other electromagnetically through microstructures in the mitochondria that create electromagnetic waves. As in: your brain & nervous system could theoretically have “wireless” operations involved.

There’s also research suggesting that humans have more sensory capacity than the 5 we typically think of, and there are instances of military induced sensory deprivation being used to heighten sensitivity to EM Fields for use as a tool.
Other instances of these abilities could include Dowsing, which has been used successfully for centuries by many cultures (which some theorize is some sort of electrical field subconscious influence that recognizes the EMF patterns).

One thing is for certain, that we won’t ever all agree, or ever have it all figured out. But it is fascinating and beautiful how complex and ordered and purposeful our body and world is. All God’s handiwork.
