message: A correction: *acoustical* energy is an instance of *mechanical* energy. Our auditory system converts the mechanical vibrations to an electrical signal we recognize as sound. Just as *light* energy is electromagnetic energy, *acoustic* energy is simply mechanical energy. There is no transformation of mechanical to *acoustical* energy from the cone to the air. If you held your head to the mechanical cone in a vacuum chamber, you would STILL hear the sound. This is because the mechanical vibration of the cone travel from the cone to your head and resonates. Your ears pick out the vibration and will convert it to the electrical signal we recognize as sound if it's of an appropriate frequency.   —Preceding unsigned comment added by 75.12.148.193 (talk) 01:35, 1 January 2008 (UTC)
replies: text: Just like a transistor, a switch is not a transducer.  An ideal switch has no energy involved in going from off to on.  I am removing it. -Athaler 18:51, 13 November 2007 (UTC)

text: Agree. This list has become bloated beyond all usefulness. --Heron 19:50, 18 April 2006 (UTC)

text: I've done it. I hope I haven't been too bold - but the revert link is always there if you don't like my version. --Heron 20:02, 18 April 2006 (UTC)

text: While I agree, I'm not sure how to categorize them beyond "biological".  What form of energy are neural signals?  From my limited neurobiology, I seem to remember that individual neurons store the signal as electric charge imbalances, but the signal is transmitted between them as a chemical signal. -Athaler 18:51, 13 November 2007 (UTC)
thread_title: Initial posts

message: In cybernetics and systems engineering, there is a notable and well-documented usage of the term "transduction" in the Viable System Model, which refers to the transformation of signals or information. The editors of this page evidently wish to restrict this page to the transduction of energy. This restriction may be valid within some forms of engineering, but is not valid across all forms of engineering. For the sake of clarity, therefore, I am therefore changing the hatnote (and the disambiguation page on Transduction from "engineering" to "mechanical and electrical engineering". --RichardVeryard (talk) 11:51, 3 March 2008 (UTC)

message: Why do machines that convert kinetic energy into electrical energy included in typical lists of transducers? I see no reason they should not count, except a single arbitrary limitation to the definition. --Kaz (talk) 01:33, 22 July 2008 (UTC)
thread_title:  Why Aren't Electrical Generators Called Transducers 

message: According to my Computer Science Theory textbook (An Introduction to Formal Languages and Automata 4th Edition - Peter Linz), a transducer is a "more general automaton, capable of producing strings of symbols as output". However, I'm not sure how to include this information on this page. Perhaps a disambiguation page is in order to provide links to the various appropriate pages?

replies: text: As a follow up, the section Finite_state_machine#Transducers should be linked to on this page. I got here looking for that information. Somehow, people that get here need to be aware of that section. ThomasOwens (talk) 01:59, 15 December 2008 (UTC)
thread_title:  Transducers in Computer Science 

message: This link http://www.americanpiezo.com/products_services/transducers/transducers_background.html to "Utrasonic Transducer Background, Materials and Examples" has been added and taken away from External links. The page has some useful information and is not without merit, but I think it could be best employed as a reference to back up technical details presented in the article about Piezoelectric sensors. This Transducer article doesn't go into enough piezo detail to require a reference. Binksternet (talk) 23:20, 19 June 2009 (UTC)
thread_title:  Piezo Ultrasound link 

message: The article starts off by saying that a transducer transforms one form of energy to another. A photoelectric cell is such a device. However this is not listed in the applications. The French article says that a transducer is a device that converts one physical signal to another. This is not the same definition!!

thread_title:  Is the definition satisfactory? 

message: If someone could be so kind as to explain the etymology of the term, that would be useful.
I make this request because in electronics, many names are based on existing things (for example, transistor comes from TRANSference resiSTOR, modem = MODulator/DEModulator, CMOS = Complimentary MOSFET [Metal Oxide Semiconductor Field Effect Transistor], and transceiver = TRANSmitter/reCEIVER.) 
So, I'm curious of transducer has a similar origin.  — Preceding unsigned comment added by 24.5.207.235 (talk) 05:59, 19 October 2018 (UTC)
