A '''dynamic torque sensor''' is an [[Electronics|electronic]] measurement device used to measure and record [[torque]] variations in rotating or dynamically moving [[mechanical systems]]<ref>{{Cite patent|number=US8752439B2|title=Dynamic torque sensing system|gdate=2014-06-17|invent1=HYTE|inventor1-first=JEFFREY Alan|url=https://patents.google.com/patent/US8752439B2/en}}</ref>. As compared to static torque [[Sensor|sensors]], which measure torque when the object is stationary, dynamic torque sensors specifically measure rapid fluctuations in torque<ref>{{Cite journal |last=Mateev |first=Valentin |last2=Marinova |first2=Iliana |title=Magnetic Elastomer Sensor for Dynamic Torque |url=https://ieeexplore.ieee.org/document/9097051/ |journal=2019 19th International Symposium on Electromagnetic Fields in Mechatronics, Electrical and Electronic Engineering (ISEF) |pages=1–2 |doi=10.1109/ISEF45929.2019.9097051}}</ref>. Thus, they provide valuable insights into real-time mechanical performance<ref name=":9">{{Cite journal |last=Karki |first=Dipesh |last2=Dura |first2=Hari Bahadur |last3=Poudel |first3=Laxman |date=2023-12-30 |title=Design, construction and performance analysis of dynamic torque transducer |url=https://www.nepjol.info/index.php/jiee/article/view/43809 |journal=Journal of Innovations in Engineering Education |language=en |volume=6 |issue=1 |pages=118–123 |doi=10.3126/jiee.v6i1.43809 |issn=2594-343X}}</ref>.

These sensors are crucialused where precise [[Control engineering|control]] and monitoring of torque are required, and they play a major role in [[Safety|operational safety]]<ref>{{Cite journal |last=Ahmed |first=Rocksana N. |last2=Akram |first2=Muhammad |last3=Iqbal |first3=Sajid |last4=Bilal |first4=Muhammad |title=Design and Analysis of Joint Torque Sensor for Safe Human-Robotic Collaboration |url=https://index.ieomsociety.org/index.cfm/article/view/ID/5340 |journal=4th European International Conference on Industrial Engineering and Operations Management |language=en |publisher=IEOM Society |volume=11 |doi=10.46254/EU04.20210030 |isbn=978-1-7923-6127-2}}</ref>.
