Thanks Bob S,
I will give it a shot.
Its actually really interesting how these electrical probe stations actually work. I don't what is actual data or what is derived data.
i have spoken to a few of them on the phone asking how to calculate the polarization from the current obtained...
For my calculations I am taking the current obtained (amperes) and mutilpying by the difference in time. I then divide by by the area of my capacitors and I believe that will yeild (C/m^2) or polarization.
But looking at the data obtained by some colleagues from a machine that does the...
Hey Berkeman,
Ferroelectric capacitors are used for mostly nonvolatile memory devices. My particular ferroelectric capacitors are comprised of SRO top and bottom electrodes with PZT material inbetween.
I am using a simple 3 probe station to collect my data. I use triangular or sin waves...
Hey All happy holidays,
Some time back I took electrical measurements on a ferroelectric capacitors in which I would apply sin or triangle waves for a certain amplitude (typically 4-5volts) and I collected/mointered/measured the current. I then was hoping to take that current and calculate...
Hey All,
This is a question I have faced many times, but I never fully grasp the difference.
All ferroelectrics are piezoelectric, but not all piezoelectrics are ferroelectric...
I understand that ferroeletrics are due to their noncentrosymetric crystal structure and they can therefore...
I was thinking something a long the lines of;
You have a 1000 N force striking a block of PZT that has a 20 cm by 20 cm area and that has a thickness of 3 cm. How much voltage and power is created.
What you know: Youngs mod, piezoelectric coef, relative permitvity, etc.
Step 1)...
Hey I am looking for an example problems that have piezoelectrics generating electricity.
I would like to have and use a simple problem in which a piezoelectric is squeezed to generate electricity. Does anyone know where I can find such problems and solutions?
Hey All,
Is there a cooling system similar to your car's radiator coolant system that does require a fluid pump?
I am looking for a simple system that will behave similar to such a system, but the difference in heat ( or resulting pressure) from hot source to cold area (which would be...
OK so my labmate was holding out!
He had the same exact board and I was able to construct the circuit just like the lab.
So far results are mixed it works and then it doesnt.
Berkeman, do you know of any sawyer-tower based circuits that would work for studying PZT capacitors? We want...
Berkeman, thanks for all the help.
I attached a picture of the board I got from Radioshack.
The ferroeletric cap. and linear capactior look exactly the same as the picture from the lab report. We made the ferroelectric cap. which is why we are testing to see if it will work. I bought...
I can do this but then I guess how are the connections getting to the wires and capacitors. This was confusing to me as well when looking at the pictures in the lab
Wow quick response.I thought that by having it on that strip would make it all in series. Should I connect it sockets that are connect by the strip?
I am a novice when it comes to using this boards/ making this sawyer-tower circuit.
Hey thanks Beckman!
Ok last question. I could not find the exact same breadbox electronic circuit board. I was able to get a simple one from radioshack and I was wondering if this will work.
I tried to duplicate the exact circuit from the earlier pdf. I attached a sketch of the circuit I...
