I have contacted them via email, but in case they don't respond, what do you guys think the specs of the PZT were given the results? I'm wondering if what Alec linked would work at an equal/better pace on a battery.
Thanks for the explanation!
I think I understand now, but I still don't understand the exact power output of it.
However, I am serious about "recreating" the experiment in the paper.
Looking at the Piezo you linked, do you think it would charge at the same rate (or even outperform) the one in...
Amazing!
You mentioned a DC-DC conversion, but wouldn't you need an AC-DC conversion since I thought the output was AC?
Also, where can I get the PZT they used, I'm trying to find similar ones online but there's lots of terms I don't understand :P
Ah okay, I understand alec.
So, in this article, https://institutes.lanl.gov/ei/pdf_files/JIMSS2005.pdf
A 750 mAh battery charges in 7 hours. Could the PZT output be run through a transformer that would increase the volts to 3.7? In theory, wouldn't that make the battery charge in 21 hours?
Oops, I meant in terms of recharging batteries, not in general >_<
For example, in this (2005) article they recharge a 1.2V battery https://institutes.lanl.gov/ei/pdf_files/JIMSS2005.pdf.
Any similar studies also use 1.2V, one of which stated that the root-mean-square voltage produced was 1.18...
So another thread here got me thinking about piezoelectronics.
From what I saw there and from what I can find, people have only been able to produce voltages capable of charging 1.2V batteries. Are there any that are capable of charging 3.7V batteries or has our technology not progressed that far?
Thanks. When I look at the specs it shows a wide range of frequencies at various voltages. How/can I control this? Also, am I right about the other part. If so, how can I modify it?
Remember, layman terms please.
I'm not well versed in electrical engineering, but I was looking at this. http://www.precisionmicrodrives.com/vibrating-vibrator-vibration-motors/pager-motors-erm-motors
It suits my needs for a project, but I need to modify some aspects of it.
In layman's terms, can someone explain to me how I...
@BvU I just realized, is there any sort of "magnitude" in vibrations (again, not my field)? Like if I had a 50 hz vibration (since that is the resonance frequency), if I change the amount/size of vibration, is there any difference in the output?
I mentioned in my original post that it should be at most a few centimeters or inches. Thanks for the cell phone motor idea, I'll be trying that one out. The more vibrations, the better though :P
I'm creating something as a side-project, but I've encountered a problem in a field I'm not well-versed in.
There is a material I am looking to excite with a resonance frequency of 50 Hz.
I need the smallest possible device to create the largest amount of vibration, I've looked into some small...
I understand that, but I was reading this the other day.
http://www.rh.gatech.edu/news/55147/improved-nanogenerators-power-sensors-based-nanowires
And from what I understand, when the nanogenerator is excited by mechanical energy, the sensor can operate.
Another way of saying what I'm asking is...
I know perpetual motion is by no means possible, but I want to make something self powered, in the same sense.
I don't have too many resources, but I am looking to make something whose own excitation would power the machine, for say, an hour.
I.e. pushing a button that would cause something to...
I'm fascinated by the prospect of them, but I can't seem to find much information/progress online aside from like small sensors which aren't quite the same thing.
Has there been anything developed that is a self powered vibration generator? As in, it vibrates and then is powered by its own...
