Special Issue Information

Dear Colleagues,

MEMS (microelectromechanical systems) and NEMS (nanoelectromechanical systems) are some of the most famous interdisciplinary research fields, requiring knowledge about a variety of research areas such as biotechnologies and nanotechnologies, as well as micro/nano-fabrication techniques.

The intersection of these technologies and the creation of integrated systems will impact many application areas, including medical research and diagnostic systems. Small, low-cost, low-power medical devices are essential for improving health care delivery, screening multiple medical diseases at the point of care, and detecting infectious pathogens associated with pandemic illnesses in global health applications.

The aim of this Special Issue is to gather original contributions or review papers from researchers that are actively engaged in developing new ideas and providing critical diagnostic devices which combine nanometer-scale devices and materials, such as metal and carbon nanoparticles, with molecular-recognition systems and optical, mechanical, or electronic transduction platforms to produce highly sensitive, high-throughput, and high temporal, spatial, and spectral resolution biochemical sensors. There is a strong and growing interest in research relating to life sciences and medicine, with a particular focus on bioelectronics, biophotonics and bio-MEMS, integrated circuit design, system-on-chip design, image sensor design, bioelectronics, and micro/nano-fabrication.

Nafion possesses many interesting properties such as a high ion-conductivity, hydrophilicity, and thermal and chemical stability that make this material highly suitable for many applications including fuel cells and various (bio-)chemical and physical sensors. However, the mechanical properties of a Nafion membrane that are known to be affected by the viscoplastic characteristics of the material itself have a strong impact on the performance of Nafion-based sensors. In this study, the mechanical properties of Nafion under the cyclic loading have been investigated in detail. After cyclic tensile loading (i.e., maximum elongation about 25% at a room temperature and relative humidity about 40%) a time-dependent recovery comes into play. This recovery process is also shown being strain-rate dependent. Our results reveal that the recovery behavior weakens after performing several stress–strain cycles. Present findings can be of a great importance in future design of various chemical and biological microsensors and nanosensors such as hydrogen or glucose ones. Full article
