What is the Relationship Between Piezoelectric Materials and Electrical Output?

AI Thread Summary
Piezoelectric materials generate low-current voltage pulses when deformed, typically producing currents in the range of 50-100 microamperes under realistic loads. There are no specific tables available detailing the electrical output per gram of material under a 1N force. The Wikipedia article on piezoelectricity provides useful references for further data. For detailed operational parameters, resources like the Mide Volture datasheet can be consulted. Understanding these outputs is crucial for applications in energy harvesting devices.

hello!

what is the maximum of electrism we can get from piezoelectric materials? can you give me some examples, or are there any tables, showing for each gram of piezoelectric material, applied a force of 1N, we get 1 ampere constant(?) current or something?

thanks!

Piezoelectric solids give a low-current voltage pulse as they are deforming. I don't know of any tables.
 
The Wikipedia article on piezoelectricity has discussions. The reference links in the article point to places where you might find the data you seek.
 
This is a typical small 'energy harvesting' device operational parameters.

Expect to see currents in the 50-100uA range with realistic loads.

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'How can I find the cleanout for my building drain?'

I am a long distance truck driver, but I recently completed a plumbing program with Stratford Career Institute. In the chapter of my textbook Repairing DWV Systems, the author says that if there is a clog in the building drain, one can clear out the clog by using a snake augur or maybe some other type of tool into the cleanout for the building drain. The author said that the cleanout for the building drain is usually near the stack. I live in a duplex townhouse. Just out of curiosity, I...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
