Editing Gyrator (section)

== In other energy domains ==
Analogs of the gyrator exist in other energy domains.  The analogy with the mechanical gyroscope has already been pointed out in the name section.  Also, when systems involving multiple energy domains are being analysed as a unified system through analogies, such as [[mechanical-electrical analogies]], the [[transducer]]s between domains are considered either transformers or gyrators depending on which variables they are translating.<ref>Clarence W. de Silva, ''Mechatronics: An Integrated Approach'', pp. 62-65,  CRC Press, 2004 {{ISBN|0203502787}}.</ref>  Electromagnetic transducers translate current into force and velocity into voltage.  In the [[impedance analogy]] however, force is the analog of voltage and velocity is the analog of current, thus electromagnetic transducers are gyrators in this analogy.  On the other hand, [[piezoelectric transducers]] are transformers (in the same analogy).<ref>Forbes T. Brown, ''Engineering System Dynamics'', pp. 57-58, CRC Press, 2006 {{ISBN|0849396484}}.</ref>

Thus another possible way to make an electrical passive gyrator is to use transducers to translate into the mechanical domain and back again, much as is done with [[mechanical filter]]s.  Such a gyrator can be made with a single mechanical element by using a [[multiferroics|multiferroic]] material using its [[magnetoelectric effect]].  For instance, a current carrying coil wound around a multiferroic material will cause vibration through the multiferroic's [[magnetostrictive]] property.  This vibration will induce a voltage between [[electrode]]s embedded in the material through the  multiferroic's [[piezoelectric]] property.  The overall effect is to translate a current into a voltage resulting in gyrator action.<ref>Haribabu Palneedi, Venkateswarlu Annapureddy, Shashank Priya and Jungho Ryu, [http://www.mdpi.com/2076-0825/5/1/9/htm "Status and perspectives of multiferroic magnetoelectric composite materials and applications"], ''Actuators'', vol. 5, iss. 1, sect. 5, 2016.</ref><ref>Nian X.
