    In this work, a three-component composite elastomer consisting of poly(di(ethylene glycol)methyl ether methacrylate) (PMEO2MA), 110 nm spherical silica particles and multilayer graphene (MLG) is fabricated and its various functions brought about by the characteristic morphology formed by silica particles and MLG are clarified. The presence of silica particles greatly improved the dispersibility of MLG in PMEO2MA, allowing more MLG to be filled. The relative dielectric constant (ε) of the composite elastomers can be increased by increasing the amount of MLG while suppressing the increase in dielectric loss tangent (tanδ). The thermal conductivity of the composite elastomer peak in the middle of the increase in MLGs when the silica particles are not filled, whereas the silica particle-filled system is able to fill the MLGs up to a higher volume fraction and shows higher thermal conductivity. The dynamic viscoelasticity analysis of the composite elastomers shows that the filling effect of MLG is more remarkable in the composite elastomer containing 40 vol% silica particles. The loss factor of vibration damping is found to be larger in the 40 vol% SiO2 - 2.8 vol% MLG composite elastomer over a wider frequency range than in the non-MLG samples

    The soul of ActiveCube: implementing a flexible, multimodal, three-dimensional spatial tangible interface

    ActiveCube is a novel user interface that allows intuitive interaction with computers. ActiveCube allows users to construct and interact with three-dimensional (3D) environments using physical cubes equipped with input/output devices. Spatial, temporal, and functional consistency is always maintained between the physical object and its corresponding representation in the computer. In this article we detail the design and implementation of our system. We describe the method we used to realize flexible 3D modeling by controlling the recognition signals of each face in each cube. We also explain how we integrated additional multimodal interaction options via a number of sophisticated I/O devices and the inclusion of a second microprocessor in our cubes. We argue that ActiveCube, with its current real-time multimodal and spatial capabilities, is ready to enable a large range of interactive entertainment applications that were impossible to realize before
