Piezoelectric speaker element generates electricity

[FineHawaiianArt]

i loved your walking on the floor idea. their are however some engineering and cost issues to contend with. perhaps a more efficient back massager, energy wasted in the handle could be translated into power that would recirculate back into the massager unit and reduce the cost of operation.

thank you for this video

[mikeakaspike]

By the way just found out tokyo is using your idea in sidewalks...

[piper4seeformerly]

Wow, that's a brilliant idea: to put a bunch of piezoelectric speakers into the sidewalks and as people walk over them they create electricity.

[zzzlt]

or kids can put in the shoes and led and when walking led flash and flash and flash...

[brsqrd1]

You are brilliant.Go to u tube, Monolith Biocrete Biobloc

[graceman25]

I like your idea about using this effect to generate electricity from walkways.

[mynameisjamesj]

This guy has got an amazing point, if someone made the peizo electric effect more efficient and started selling it as a carpet to save or generate energy for the home.... well you get the picture!

[CoolDudeClem]

I did this with a ordinarry speaker and an led, it worked but I had to tap the cone pretty hard to get the led to blink. Also I tried using a piezo speker in a home made microphone and it worked, the sound quality was pretty clear, but no low freqencies, whitch is understanderble.

awsome lab man! :O do want!

[Bp1033]

I found that out when I was six when messing around with an electronics kit (the little earpiece is a piezo). I miss that mess of cardboard and springs. :D

[markdem]

i dunno much about piezo speakers but it makes sense to me. i mean, you can generate electricity from moving a magnet through a copper coil, which is EXACTLY what a speaker is. so instead of putting current in to produce movement, you put in movement to produce current

"I did not know that" ... it's elementary school lesson. Very strange guy ....

[mattsyme87]

Haha, I first realised that you are from Dutchforce by your lab, didnt even notice the name. Some cool vids on here man.

[80amnesia]

so i'm not the only twisted minded , thanx for the video

[TNFlightNurse]

I need this lab so badly...

[Pujc]

Thats not new , such are in Lighters, and , the kitchen torch that one there you must pus the button , and many time lil sparks jup ower (tere one there are battery-less) and use that on many places as like furnace igniter ....ect ect ...

[Bp1033]

@Pujc those use magnetos.

[rayroy3]

dude, no offense, but HOW DID YOU NOT KNOW THIS?!? I mean you have such an awesome looking lab its surprising. aren't you curious WHY the material has this magical property? piezoelectric elements are not just made of crystal, they are also made of ceramics, and even wood. the effect comes when a specific and uniform atomic structure is deformed. resonate a piezoelectric element and you can get more stable, more usable energy, yes. look into cymatics.

[Jo0ngle]

@rayroy3 Not surprisingly, I don't know everything. I do however like to experiment out of the blue, I have no scientific schooling other than basic school required by the gov. that everyone takes. The instrument guides me, helps me figure out how things work without having 10 years of math & physics theory, it like a practical hands-on approach to learning, that always worked for me. Thanks for the cymatics hints. we had a discussion about how to make these at the dutchforce electronics forum.

[Pilesofplenty]

Mount it to a bike and let it smack the spokes like they use to do with playing cards.

[vwest7ife]

This is exactly how ceramic phonograph cartridges work... the needle wiggles the piezo element, and then the piezo makes electricity matching the sound on the disc.

Is that a Toshiba Libretto mini-laptop computer in the backgroup?

[Jo0ngle]

@vwest7ife - Yes, that's a Libretto 70ct, with a small Color TFT screen, running on windows - over 13 years old I assume, but works amazingly well, including the Lithium battery.

[Vinylrecordsneverdie]

Wow, I never knew that 'til now! Neat demo!
