Special Issue Information

Dear Colleagues,

Sensors are an integrable part of modern technologies and thus very important for sustainability as they are the eyes of the control systems which keep all the processes running. All safety warnings are generated by sensing signals, which then are used to shut down uncontrollable devices or to readjust input parameters, so as to maintain our every day technological processes within acceptable safety limits. It is not surprising that a modern car accommodates 60 to 100 sensors on board which provide continuous information to the car ‘s CPU about vital engine parameters for its normal operation and safety (such as internal temperature, pressure, fuel concentration), about the exhaust gas quality for compliance to environmental regulations, about safety conditions for safety activation processes (such as collision warnings). The modern trends in sensor technology are miniaturization due to size/weight restrictions, multi-parameter sensing, improved sensitivity, integration/embedding. These trends can only be realized with the use of new, advanced, smart materials utilizing both new and conventional research fields such as nanotechnology, large scale integration, flexible design, composite material synthesis, signal processing etc. The scope of the current issue is to bring all these edge research fields in one issue so as to serve as a reference for tomorrow’s sensor technology. As new materials with fascinating properties are continuasly developed, such as flexible materials, 2-D materials, nanoporous materials, the current issue will enrich the up-to-date literature on sensing materials with the new advances. All sensor technologies are welcome.

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. Sustainability 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 2400 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.

The magnetoelastic materials find many practical applications in everyday life like transformer cores, anti-theft tags, and sensors. The sensors should be very sensitive so as to be able to detect minute quantities of miscellaneous environmental parameters, which are very critical for sustainability such as pollution, air quality, corrosion, etc. Concerning the sensing sensitivity, the magnetoelastic material can be improved, even after its production, by either thermal annealing, as this method relaxes the internal stresses caused during manufacturing, or by applying an external DC magnetic bias field during the sensing operation. In the current work, we performed a systematic study on the optimum thermal annealing parameters of magnetoelastic materials and the Metglas alloy 2826 MB3 in particular. The study showed that a 100% signal enhancement can be achieved, without the presence of the bias field, just by annealing between 350 and 450 °C for at least half an hour. A smaller signal enhancement of 15% can be achieved with a bias field but only at much lower temperatures of 450 °C for a shorter time of 20 min. The magnetic hysteresis measurements show that during the annealing process, the material reorganizes itself, changing both its anisotropy energy and magnetostatic energy but in such a way such that the total material energy is approximately conserved.

Advances in cell and tissue therapies are slow to be implemented in the clinic due to the limited standardization of safety and quality control techniques. Current approaches for monitoring cell and tissue manufacturing processes are time and labor intensive, costly, and lack commercial scalability. One method to improving in vitro manufacturing processes includes utilizing the coupled magnetic and mechanical properties of magnetoelastic (ME) materials as passive and wireless sensors and actuators. Specifically, ME materials can be used in quantifying cell adhesion, detecting contamination, measuring biomarkers, providing biomechanical stimulus, and enabling cell detachment in bioreactors. This review outlines critical design considerations for ME systems and summarizes recent developments in utilizing ME materials for sensing and actuation in cell and tissue engineering. Full article
