What is a piezoelectric crystal? Answered

I kind of know what it is, but i need a professional (Professer? Kiteman, my hero! LoL...) awnser. I know it is some form of crystal that when pressure is applied, positive (ions?) form at one side, and negative at the other. Also, how does a piezoelectrical ignitor work? What crystal does it use?

HELP WITH PIEZOELECTRIC EXPERIMENTS?

Hi, I am a researcher and I am interested in the piezoelectric qualities of certain materials, specifically quartz or bone and wondered whether anyone had experience of passing sound through quartz/crystals/animal bones? Is it possible to use one of those material to carry sound? I know that glass windows can be used as large bone conducting speakers, just wondering if anyone has any experience of this? I haven't done any hands on experiments myself as I am still at the research stage. Any advice would be appreciated and a big help! Thanks

How much and how efficiently can a capacitor store charge?

I recently found out all the items required to build this project: https://www.instructables.com/id/Electricity-Generating-Footwear/ .  I don't want to buy the power bank, so I though about using rechargeable batteries. But I had none, but I had capacitors and I thought of using them.  These capacitors 1000 uf . I am thinking about soldering 5 of them in paralell so that I have 5000 uf storage capacity, But I am concerned how well it would work, if at all.   Can this store upto the amount of charge that a powerbank can? Can it actually charge up at a constant voltage if I use it?  Thanks for helping!

Are there any alternatives to piezoelectric transducers?

I saw a post about an energy-generating device on shoes which generates electricity when walking. Piezoelectric transducers were used to generate energy but not enough to charge the battery full or even half full. Are there alternatives to Piezoelectric transducers that generates more energy than piezo? Thanks.

Effectiveness of sugar as a piezoelectric material

Most of the sites discussing piezoelectricity mention that sugar crystals can be used, but I have not found any examples of them being used. I've just tried it with about a 1cm chunk of low quality (conglomerate of small ~3mm crystals) crystal, and got a good 100mV wave when tapped with a pencil. I've not tried applying a signal to it yet, and some better single crystals are growing at the moment, so I was wondering how well it works compared to commercial piezoelectric compounds. I've not done anything like this before, so if anyone knows where I can find information of the best way to mount and apply a signal to the crystal, it would be appreciated. Thanks in advance.

Piezoelectricity Experiments. Help Needed!

I'm currently experimenting with piezoelectricity.And at the moment my experiment is limited to just a few piezo sparkers extracted from cigarette lighters.The sparker works with observable voltage spike on my multimeter. No voltage spike however when I use the tiny crystal (the size of a zippo flint) taken out from the sparker.I was trying to replicate this experiment (without the oscilloscope):Piezoelectric Rochelle SaltAnother thing, Would continuous vibration produce continuous voltage?It is known that piezo crystals produce high voltage, yet very low current. What are the options to increase the current? Would winding un-insulated copper wire around it (or any kind of contact with conductive metal) increase the current? Apart from lighter, what other surplus sources of piezoelectric crystals (i.e. quartz, PZT, Rochelle)? Can the crystal in RC toys, radios be used to generate electricity? Although there is the option to grow my own Rochelle salt, I'm not looking into it at the moment since it's going to take quite a while to grow.Thanks in advance!

How to design a piezoelectric speaker with high impedance at 30 - 150 watt?

I'm looking for a guide on how to build and measure a piezoelectric speaker with regular impedance 4ohm , 8ohm , 16ohm , with watts from 30 up to 150watts rms , the purpose use is for amplifiers such as hifi amps , guitar tube amps , also i want to know if it possible and how to make a high impedance piezoelectric speaker above the 1kohm for a OTL Tube Amps , to solve the problem instead using many tubes to lower the high impedance , to use a piezoelectric design that has the high impedance for example 4000ohm in this case no need for output transformer or too much of tubes, plugging the tubes directly to a piezoelectric speaker , the size of the speaker it may be bigger than a regular piezoelectric element due to the high impedance and adding other material for resonance , anyone can help? please :)

How do you use a piezoelectric ceramic to light an LED?

I have a small, round  piezoelectric ceramic sensor made from PZT (Lead Zirconate Titanate) material that I would like to try out to see how much mechanical force I need to apply to light a 5mm LED. The piezo ceramic has already been soldered with two wires (negative and positive). Nevertheless, I am completely new to creating circuits that involve a piezo ceramic. As a result, I have no idea whatsoever on how to properly connect the piezoelectric ceramic to the LED as to light it up. I have connected the two together before and applied force on the ceramic to see if it created some sort of charge, yet nothing occurred.

Bite force transducer embedded in a gumshield

I am a quadriplegic and paralysed from the shoulders down. I am working on a project to allow me to control a go kart. I have limited use of my arms which should allow me to control the steering but I am trying to get another degree of freedom to control acceleration and/or braking One of the ideas is to use a piezoelectric type force transducer in the mouth to control and acceleration via an arduino or similar. The transducer would detect bite force and it would be converted into control signals for the throttle and/or brake. It would be embedded in a gumshield and it would be acceptable to have a cable coming from the front of it to the control System. I am wondering has anyone worked on such a project and could anyone point me in the right direction please. The gumshield may end up looking something like the image here.

Is it possible to make a wearable Heart Beat Sound amplifier?

This is for my final project for one of my university papers and what I want to do is to make a object that can amplify or create the sound of the heart and can either worn on the hand or the neck like a necklace, as a form of communication and/or self expression. Visual aesthetics are important for this one so ideally, if its possible Id like to make this wearable object portable and super simple since I'm an amateur when it comes to anything electrical like this! I did see another question on this site which was practically the same as mine, amplifying the sound of the heart beat for a project and one of the comments mentioned using piezoelectric elements to pick up the movement of the veins and therefore create a sound through an amp and a speaker. This would be perfect for my project even though its not the exact sound of the heart but its doable, except connecting it to an amp etc isn't exactly small or compact enough for it to be wearable.  (Here's the web address to the other question I mentioned above: https://www.instructables.com/answers/How-do-I-connect-a-stethoscope-to-a-speaker-How-/)  So...is there any other way to use piezoelectric elements to pick up the movement of the veins and output it somehow preferably through sound, but representing it visually through LED lights could also be an option, but again, how do you make this inexpensive, wearable and simple to make?? Any suggestions anyone?? Thanks :)

HAARP mind control?

Allegations have been made that the HAARP project is behind mind control experiments. The ex governor Jesse Ventura, interviewed a professor who demonstrated in his show that it is possible to send messages to people's minds without any need for hearing. The professor put two piezoelectric transducers on Ventura's chin and Ventura claimed to be able to "hear" music in his brain. Real science or pseudoscience? If this device could be made, wouldn't this device help people without hearing? What about the possibilities of learning devices or communication? I believe that this device could put thoughts on people's minds but not necessarily control them (unless it is an easy suggestible subject). Please watch a segment of the show and share your opinion:

Does Voltage Or Current Kill Electronics? Answered

I've heard it a million times "It's the amps that kill".  But what if we are talking about electronics?  Would something that is 1.5 volts at an amp affect an electronic device? What if I had something at 10 kV, but virtually no current, like a piezoelectric ignitor?  (Maybe both of these examples would, I'm not sure,  but which is more likely?) Just wondering if someone can tell me whether it is mainly the volts or amps that fry electronics. And also how this happens. Does the high voltage short circuit things? Or is it the current that would overheat the small little circuits inside? I'm thinking that both are possible, but I'd like to know which is more likely to kill electronics, voltage or amperage?

How would I make a sensor sense motion coming at me from behind while I'm moving forward?

I'm trying to make a small sensor that would detect a large object coming at me from behind at about 60mph while I'm moving forward at around 7mph. What kind of sensor would I use? I looked up the different types and I found Passive/active infrared, optic-based, piezoelectric, and ultrasonic. I tried to figure it out myself and my best guess is ultrasonic? Like what cars use to detect deer, they use "ultrasonic airflow sensors". Ideally the sensor would beep and get louder or faster as the object approaches. Would I use an arduino? I'm very new at this :/ Thanks for any help!

Does anyone know how to make piezo triggered Kick drum light?

Does anyone know how to make piezo triggered Kick drum light? One that lights up the inside of the drum when hit? I want to make one for my drummer. I plan to use the flexible strings of LEDs I've seen available to line the inside of the front kick drum head. Then some how wire up a piezo (either mounted in the shell or on the drum head itself) trigger so it flashes when he uses the kick pedal. There are some vents to feed wires through so if an exterior power source is necessary, thats not a problem. I know it will need power of some sort ha, but batteries are preferable. If anyone could help me with a circuit and/or a list of components that would be great! Thanks in advance!

Electric Ukelele & Viola, Violin or Octave Violin Build

I am searching for inexpensive means to create aesthetically pleasing electric stringed instruments. I started this project when I started playing viola years after I was forced to quit private lessons. I discovered the F-f-fiddle on openfab.com which is a super rad 3d printed electric violin but since I do not have access to any 3D printer in the tiny town which I reside in, I sent the files to an online 3D printing business and they quoted me at least $500 just for the Fffiddle body! I didn't even bother to ask for a quote on the electric ukelele which I want to print & build so badly as well. I am interested in this project so that I can possibly help low income public school students in creating their own instruments to inspire them to take up an instrument and show them how much fun it can be to create something by yourself rather than buy. I am especially interested in acrylic plastic/lucite/celluloid, resins, exotic wood, recycled plastics, plastic injection molding, piezo pickups, and any other interesting materials that could be incorporated into these projects. I have been studying luthier tools, supplies, etc, along with design/fabrication of lucite/acrylic stringed instruments, furniture and other home goods. 3D printing/scanning, vintage celluloid guitar finishes, pre amps, recycling plastic bottles, landfill harmonic instruments, leather, pearl inlay, metallic finishes, enameling kilns, metal smithing, hand engraving & everything in between. I have been a mixed media artist for nearly my entire life and my father was a jeweler. I am going to find a way to create some functional and beautiful instruments no matter how long it takes me to narrow down the right combination of materials and how to make them, model them, mold them, dye them, etc! The photos attached are simply inspirational photos which I have collected over the past 6-8 months. Many of them are possibly patented, licensed, etc and I do NOT want to simply RIP OFF any of these photos! Please email me at svbacklund@gmail.com if you believe you could help me with my low income student instruments program or leads on 3d printing grants for public schools or anything else that may help me on my latest project or contact me directly via my instructables question here. I especially am interested in creating an electric violin which incorporates both classical and contemporary design. Any advice? Could you help?

Dorkbot Anglia 30th June 2011 - brief report, and an announcement.

It was a very pleasant evening, once I got parked (a lot of Bury St Edmund's car parks close early).  Only about two dozen people came to hear the speakers, but many more would have been cramped in the main room of the small gallery.  Bowls of snacks were out, along with a small "bar" (a table of bottled beers, available for a donation to the evening).  Unfortunately, whilst I remembered to take a notebook, I forgot to take my camera... Sitting with a beer, surrounded by Art and listening to enthusiastic Makers in the company of like-minded folk.  Mmmmmmm. Smith's Row curator, Rosie Grieve, kicked off the evening with an outline of how and why she ended up offering to host Dorkbot and arrange speakers for the event. The second speaker, and the main highlight for me, was Fraser Reich of Kore Technologies, showing off his mass spectrometer in a briefcase.  It's not a brand-new technology by any means (the machine he brought had been under constant vacuum for eleven years), but I am old enough to remember when samples had to be sent to dedicated buildings, and results came back days later, and Fraser's enthusiasm for the machine (it's largely his baby) was a joy to listen to, as he did a live test of the air in the room (benzene! toluene! silicone!) and the vapours given off by an orange, turning out useful results in only ten seconds. The third speaker, Lee Patterson, is a sound artist who works with recordings made "in the wild".  He attaches cheap piezoelectric microphones (so beloved of makers of cheap electric guitars) to street furniture, or makes his own hydrophones and records the lives of invertebrates and event weeds in the urban ponds of his native Manchester (MP3 files available here).  He talked us through his work, and also gave a live performance of nuts and seeds burning, attached directly to two of his microphones - the sound was... weird.  It sounded like tunnel-traffic, trains and room full of over-boiling kettles.  Although Fraser was the better speaker, Lee inspired in me more ideas for future projects.  I took notes. The final speaker, Anton Woodward, talked us through his work on stage automation - the sort of bespoke-built devices that fly actors through the air, lift scenery out of the stage, and don't quite drop chandeliers on the audience (yes, that was his).  He took us through a brief history of stage automation, from the early days when each motor had to be controlled by hand, live, by an operator as well-rehearsed as the actors, to modern systems that can automatically throw tonnes of equipment around the theatre with hundreds of motors, all under computer control, and showed us video of the kit in action.  His work includes Phantom of the Opera, Billy Elliot, and he has now moved into screenwork in Bollywood and  X Men: First Class (he created the mechanics of Banshee's flight sequences, which involved hanging the actor stationary in a harness, then shooting the camera towards his face at 40mph...). A very enjoyable evening, I shall continue to get to Dorkbot Anglia events whenever I can. ------------------------------------- For future notice, the event was compered by John Bowers of the Curiosity Collective, who have a show coming up in Ipswich soon, an exhibition of "interactive curiosities" with the general theme of "time". I don't know if I'll get to that one, but if I do, I'll definitely take my camera...
