A new self-fluffing fabric from Otherlab changes its insulation dynamically in response to temperature -- entirely without a power source.
Researchers at the University of Utah have produced a prototype pair of smart glasses that keep the world in focus by using flexible lenses and piezoelectric pistons.
IEEE Spectrum Webinar: Simulating Graphene-Based Photonic and Optoelectronic Devices - 11 June 2015
Sponsored by COMSOL
Graphene – a material that has just recently been integrated with metamaterials, plasmonic nanoanteannas, waveguides, and photonic crystals - is establishing itself as a versatile and dynamic platform for realizing electrically tunable devices in hybrid nanophotonics and optoelectronics due to its excellent electrical and optical properties. In contrast to a single-layer graphene (SLG) sheet, nanopatterned graphene structures are shown to support highly confined surface plasmon modes that can be electrically tuned and have incredible potential for spatial and temporal light modulation in the mid-infrared range. In this presentation, we guide you through the essential steps of how to simulate such devices using the full potential of COMSOL Multiphysics®, first by starting with the basics of SLG modeling, and then by including approaches to multivariate modeling of the SLG sheets and nanostructured graphene in time and frequency domains.

Smart Fabrics and Interactive Textile (SFIT) based systems are conceived as the integration into textile of sensors, actuators, computing, and a power source, with the whole being part of an interactive communication network. Such systems could only be envisaged through a combination of advances in fields as fiber and polymer research, advanced material processing, microelectronics, signals processing, nanotechnologies, and telecommunication.Textile is the common platform where smart materials in the form of fibers are integrated, where the properties of the material are augmented through combination of chemical surfaces processes, and where the structure of the fabric allows the use of redundant sensor configurations Promising recent developments in material processing, device design and system configuration enable the scientific and industrial community to concentrate efforts on the realization of smart textiles This course will discuss the use of textile materials for sensing functions. Textile technology for sensors fabrication will be presented. Methods for characterizations will also be discussed and examples of specific applications will be presented. The course will also provide an overview of future developments.
