piezoelectric

I am working on a project that has this piezo sensor I want to know how I can solder wire to it 1)What kind of wire do I need to use 2)Do I need to place any contact points on the piezo disc (contact are metal plate placed on some piezo) 3)What is the redial and normal resonating frequency in...

Hi, im doing a project on piezoelectric disks where I want to harvest energy from them. I have ordered some and waiting on them, I wonder if someone is familiar with working with these and could answer some questions. thanks in advance

Hello, I am a farmer not an electrical engineer, but I have recently been trying to learn more about the electronics we use in farming. I have been trying to troubleshoot the grain loss system on our combine that hasn't worked in years. Keeping in mind that I am a farmer, as I understand it the...

Hello everyone! :) I am having difficulty in understanding a concept since I am not in the electrical field. I am working on a project to measure the dynamic force on a surface using embedded PVDF transducers. Based on the theories I studied so far, if I connect this PVDF to the charge...

Hi all I watched a video that someone used ferrous core and rounded a coil around it and made an oscillator circuit.. and he could make mist with it. I was wondering if we can use suitable size speaker to do the same thing.

Hello, I want to build a piezoelectric energy harvester, that can store the energy whenever it it pushed, into a standard 3,2v Li-on battery. This is a project where I want to build a powerbank, that charges itself in the shoe, through pressure onto a Piezoelectric element. My problem right...

I got some piezo discs, hook one up to my multimeter, apply pressure to disc, get voltage, switch over to measure current, get nothing. I repeat same process with a second and third disc, and get same results. Ive seen people use these, not mine, but these same piezo discs to power an led hooked...

Hi guys, Just wondering if this simple circuit will work as I expect it to. So this is for an engine, I'm utilizing multiple Piezo igniters to create a spark plug and I'm trying to figure out if this will work. I understand that this would be pretty easy to test I just don't have the...

Hi there, Recently, I have designed a new charge amplifier than can be used to implement a precision and low-cost interface for piezoelectric sensors. I have published an article about the novel proposed circuit in IEEE Sensors Journal. ( A brief information about the new proposed circuit has...

I want to detect the mechanical shock of a machine. To measure the vibrational shock I am using Minisense 100 Piezoelectric vibration sensor. I have done the feasibility test using it and it is giving output as expected. I have observed on the oscilloscope output frequency for all type...

Hello, I want to experiment with the properties of piezoelectric generator devices. I am looking to get a few PZT devices where I can stress / impact the material to produce current. I have concept to use multiple PZT devices where they will be stressed simultaneously. The PZT devices output a...

Hi Everybody, I am working on a project that needs to drive 5 (175 watts) Piezoelectric Ultrasonic Transducers, the system needs to output clear ultrasonic sound at 40 kHz (precise sine wave) The system needs to produce a very clear sound (of course not for the human ears) of 40 kHz sine wave...
