This article is the preface to the Special Issue of the Journal of Intelligent Material Systems and Structures on occasion of the Symposium A53 'MEMS/NEMS for Sensorial and Actorial Materials' held at the Euromat 2011 Conference, Montpellier, France, September 12-15, 2011. The authors outline the concept of material-integrated sensing and intelligence, which is summarized in the term sensorial materials. Such materials are understood to incorporate sensing, signal and data processing as well as communication facilities to autonomously evaluate their own condition and/or their environment. To achieve these capabilities, bottom-up as well as top-down approaches are currently being discussed. The latter is highlighted in this work. Research efforts towards it range from materials science to sensor and microelectromechanical system (MEMS)/nanoelectromechanical system (NEMS) technology, microelectronics and computer science and were covered in the underlying Euromat symposiu m. As a specific aspect linked to the envisaged autonomy and a resulting adaptivity, for example, of internal self-representation and data interpretation, potential consequences for engineering design are sketched

“…Recent progress in spintronics has led to the detection of various spin-mechanical interactions, but most of them are related to feeble forces [13][14][15][16][17][18]. Recently, there have been reports of magnetic material driven by spin-currents [19].…”

In this work, the actuation of micromechanical structures based on spin-current volume effect (SVE) using an amorphous magnetic film of Tb20Fe24Co56 (TFC) with volume magnetostriction (VM) is demonstrated, and the actuation performances are evaluated. A 2 mm-diameter circular polyimide diaphragm coated with thin TFC/non-magnetic metal (NM) films is prepared as the micromechanical structure, and Pt, Cu, and W are used as the NM film. When an AC charge current flows through the TFC/NM film on the diaphragm under an external magnetic field in the diaphragm plane and orthogonal to the charge current, an AC spin-current flows in the NM film due to the spin-Hall effect. In the SVE, the spin-current transports angular momentum from the NM to TFC films, which modulates the magnetization fluctuation of the TFC film due to the spin-transfer torque, causing the volume modulation based on spin-lattice coupling. Thus, this SVE can induce the mechanical actuation of micromechanical structures. The force generated by the SVE actuation is evaluated from the mechanical resonance of the diaphragm, and it is found that the power density of the diaphragm actuator with the TFC/Pt films is larger than 1.17×106 W/m3 at 20 mA peak-to-peak AC current under 0.72 T magnetic field. This SVE is effective as a new actuation mechanism for microsystems.

“…Templates based on porous anodic alumina are commonly used for the fabrication of new nanostructured composites based on nanoscale structures. Such nanostructures are widespread due to their unique chemical and physical properties [16][17][18][19][20][21][22]. The full extent of anodic alumina template usage in forming nanostructured materials is discussed in the review article [17].…”

et al. 2020

Inorganic-based nanoelements such as nanoparticles (nanodots), nanopillars and nanowires, which have at least one dimension of 100 nm or less, have been extensively developed for biomedical applications. Furthermore, their properties can be varied by controlling such parameters as element shape, size, surface functionalization, and mutual interactions. In this study, Ni-alumina nanocomposite material was synthesized by the dc-Ni electrodeposition into a porous anodic alumina template (PAAT). The structural, morphological, and corrosion properties were studied using x-ray diffraction (XRD), scanning electron microscopy (SEM), atomic force microscopy (AFM), and electrochemical techniques (linear sweep voltammetry). Template technology was used to obtain Ni nanopillars (NiNPs) in the PAAT nanocomposite. Low corrosion current densities (order of 0.5 µA/cm2) were indicators of this nanocomposite adequate corrosion resistance in artificial physiological solution (0.9% NaCl). A porous anodic alumina template is barely exposed to corrosion and performs protective functions in the composite. The results may be useful for the development of new nanocomposite materials technologies for a variety of biomedical applications including catalysis and nanoelectrodes for sensing and fuel cells. They are also applicable for various therapeutic purposes including targeting, diagnosis, magnetic hyperthermia, and drug delivery. Therefore, it is an ambitious task to research the corrosion resistance of these magnetic nanostructures in simulated body fluid.
