Talk:List of piezoelectric materials

Dear Fellow members

Please suggest additions and contribute to the database.

See the parent article

Wikipedia has an article on piezoelectricity. That is the article where properties are discussed. It would be confusing for readers to have two articles on the same subject. This article, I guess, could be a list of all useful or interesting piezoelectrics. But it definitely should not compete with the parent article.

If a classification scheme is being introduced (e.g., polymeric, ceramic, crystalline), it must be sourced, ideally with a textbook.--Smokefoot (talk) 12:39, 28 January 2020 (UTC)[reply]

Confusion on units for piezo coefficients

The section on Key piezoelectric properties suggests the piezoelectric coefficients are expressed as meters per volt, but then the table header says they're in (pC/N), which I'm not sure, but is that pico coulombs per newton? Maybe I misunderstand, or maybe they're equivalent, but it seems a bit confusing at the moment, and worth clarifying by someone who knows more than me. --Tleave2000 (talk) 02:00, 25 June 2021 (UTC)[reply]

Yes, I came to complain about the same thing: the unit is picoCoulombs per newton. I don't think either of these units is particularly practical - Volts per metre isn't much help to someone who is not going to be able to measure the nanometres of compression, and coulombs won't tell you the voltage, which will depend on charge separation, so the most useful unit would be volts per newton, or perhaps depending on the size of the device, volts per pascal! 2001:56A:F0E9:9B00:70C9:8143:900D:6088 (talk) 19:07, 18 May 2022 (UTC)JustSomeWikiReader[reply]
