NASA | Piezoelectric Energy Harvesting Transducers

This research project was funded in 2010 by the Innovative Partnerships Program at NASA Langley Research Center in Hampton, Va.

3 years ago, I did the same experiment with very interesting results. I used half-wave rectifier circuit to convert the energy from AC to DC, and it lights up the LED pretty brightly! All of these components were taken from the electronic waste. The project is capable of powering low-power devices such as sensors.

I'm here to verify my own ideas thank you.

NASA keep in touch so we produced battery powered by human temperature and Peltier effectively used for charging battery

I did the same experiment and able to generate around 8 to 12 volt. But the current is only within the micro amps. I hope to be able to try some new and better performance piezo material.

Long trail backpackers need a way to generate about 12 watts of electricity per day to keep their cell phones and headlamps running. Many carry almost 1/2 KG batteries to make this happen and recharge whenever they are in towns. What they need is a lightweight way to get their "juice" while hiking. A pair of insoles in their hiking shoes might be able to generate that electricity and reduce their load of gear. What do you think?

Great area of research. Keep up the good work and upscale it please. For example, large units in highway offramps to assist vehicles in slowing by extracting energy would be one way to add to the powergrid. H

[rcarver]

A little misleading. Much like electromagnetic waves, a higher frequency vibration inherently contains more energy, therefore more energy is transferred to the device.

Please share the details of the shaker used along with the piezo patch

Di recente ho fatto domanda al istituti di ricerca perchè non utilizzare i cristalli piezoelettrici o piezomeccanici per regolare con una piccola tensione le diottrie le messa a fuoco e la struttura di prismi ottici, visto che per regolare la collimazione o messa a fuoco della lente di plastica del laser del lettore cd rom, cd audio, dvd, utilizza un solenoide "quanta energia risparmia un cristallo piezoelettrico da un solenoide"?

the earth earth to quartz to dual capacitor that makes an arc flash that ionizes the air and tricks the trapped sun rays in the ionosphere into more piezoelectric on the 2nd coil with conductive top...

After almost 7 yrs of time how is everything?

Did this accomplish the desired task?
What uses are these used for at Nasa?
Was this a net loss or net gain?
Are these commercially available?
Can I get a sample?
Can I buy a sample?
Have you improved these?
Can you do an update video?

can u produce 100w from a 1mm x 1mm piezzo

[anilsharma-evmy]

NASA if we produced such devices which use centrifugal energy for charging our cellphone then it becomes a boon
We can use our mussel power 🔋 for charging many gadgets

[kenrutherford]

Mia Siochi is beautiful. I love her bob haircut

[escuelacerogrados]

Still too expensive for commercial application...

[billjohnson]

4 time efficency but 100 time more power to input ummm arnt those both the same thing??, hiw is one 4 times and other 100 times lol

[romansobczyk]

Przy dobrym projekcie da się z objętości 1m3 i częstości 100hz wyciągnąć 160kW/s i 7MV/s.😉

[billjohnson]

anyome notice we they compared the two the vibrator was way louder wen running "there" pizo device lol ya i can get 100 times more power from pizo if i vibrate it with 100 times the force lol

[redneckhippiefreak]

I am now questioning everything I ever imagined about NASA...This is about as scientific as a game of Rolette. How can a supposed Scientist overlook the factor of Mass in these equations and results? Of Corse its gonna make more energy as it Now TAKES more energy to generate the needed force.. I seriously hope the rest of NASA isnt feeling there way through science like this.

[selfhealing]

This is the most non-sense video about piezos ever!
I wonder if these 2 guys are really from NASA
