Talk:Piezoelectric sensor

I would like to know the pronunciation. — Preceding unsigned comment added by Punstress (talk • contribs) 17:18, 2 July 2014 (UTC)

I'm dubious about the claim that charges due to piezoelectricity in bones are the cause of local bone growth and replacement. Current research at stanford mechanical engineering (http://www.stanford.edu/group/biomech/faculty/carter.html) suggests that it's actually the flow of fluid through pores in the bone corresponding to the cyclic loading of the bones that actually is responsible for triggering growth.

The equations and explanations for the longitudinal and shear effects seem to be the same (except for the factor of two). What's the difference?

I suggest to remove the commercial links. —Preceding unsigned comment added by 129.132.25.167 (talk) 07:49, 25 January 2010 (UTC)

Diagram
We need a diagram like or  — Omegatron 02:17, 3 November 2007 (UTC)

Also mimic the diagrams on this page. — Omegatron 01:52, 8 November 2007 (UTC)

Frequency range ???
Anyone got any info on this ? Keller-Druck would be the people to ask. —Preceding unsigned comment added by 161.184.145.73 (talk) 21:38, 24 December 2010 (UTC)

Drastically more info needed
What is possible size, sensitivity, how long it lasts, price range... Even theory is not entirely complete

anyhow, thanks for the good work so far!

Modulus of elasticity
Up to 105 N/m²... seems like quite a small number?? Jdpipe (talk) 01:29, 23 July 2010 (UTC)

frequency range
Please note that piezoelectric sensors can and actually are used both below, in, and beyond the resonant range. Also, that there is typically much more than a single resonant frequency. Therefore the figure "Frequency response of a piezoelectric sensor; output voltage vs applied force" - is misleading simplification, only applicable to specific kind of piezoelectric sensor (possibly a guitar pickup) — Preceding unsigned comment added by 78.105.184.252 (talk) 23:48, 22 February 2014 (UTC)

Piezo transducers as sounders
I can't find a wiki entry on this anywhere. If one exists, this article should surely link to it. Tabby (talk) 21:25, 29 June 2015 (UTC)

Electrical properties section's diagram seems to be missing parallel resistance for main capacitor
the citation https://www.ti.com/lit/an/sloa033a/sloa033a.pdf has a resistance *in parallel* with the main capacitance. TI's paper calls this resistance Rp and the main capacitance Cp, while the has "Ce" but that capacitance doesn't have a parallel resistance. TI's paper says "the resistance accounts for the dissipation of static charge." That seems to be important enough to include in the model. I am just trying to reconcile what that TI article says with Wikipedia's first circuit diagram. Em3rgent0rdr (talk) 05:18, 25 April 2023 (UTC)
