Feasibility Analysis of a Textile Metal Detector Utilizing a Conductive Yarn

Research output: Chapter in Book/Report/Conference proceedingsConference contributionpeer-review


In working areas where a human is in contact with
moving machines, it is mandatory to establish a safe working
environment. Such environments are secured with electronic
sensors. In contrast to industrial production, other working areas
like forestry cannot rely on electronic sensors. Both working
areas have an approaching metal object as one cause of injury in
common. This is where a wearable metal sensing concept comes
to use. To further increase the practicability and usability of
those metal sensing devices, the sensing element is implemented
directly in the textile, which is worn on the body. A combination
of the metal sensing principles of commercially used metal
detectors and the utilisation of smart textiles as the sensing
element is the main focus of this paper. It is investigated by
using a textile yarn to detect a metal object approaching the
sensing element, by measuring the change of voltage and phase
and therefore the change in inductance. The results show the
possibility of implementing a textile metal detection sensor by
using a conductive yarn as a sensing element.
