Special Issue Information
Dear Colleagues,
Carbon nanotube (CNT) threads are piezoresistive continuous structures composed of several thousand carbon nanotubes in their cross sections that can be twisted, densified and further tailored to serve as sensors for structural health monitoring. Due to their microscale dimensions, they are amenable to integration in materials, and especially in fiber reinforced composite materials. The proofs of concept to detect damage and measure distributed strain in laminated polymeric composite materials using integrated CNT yarns are already available. Additional concepts of standalone or integrated piezoresistive strain gauges and other sensing mechanisms to monitor temperature are also being explored for the CNT yarns. This Special Issue focuses on papers that include experimental, modeling or theoretical studies about the fabrication and characterization of CNT yarns and their use as sensors to monitor the health of structures or sensing in aerospace, mechanical, civil or biomedical applications. Of special interest are studies on the piezoresistive response of the CNT yarns and the effect of their structure, geometry and loading parameters on that response. The main sensing mechanisms of the CNT yarns are based on their piezoresistive response but piezoimpedance or other mechanisms that may be tapped for temperature sensing are also of interest. The papers of this Special Issue may contribute to realize integrated, distributed and real-time sensing using CNT yarns and lead to robust and simple health monitoring techniques and maintenance of structures or devices.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
