Thermal insulation materials have a strong impact on energy efficiency of buildings which are one of the main energy consumers in the EU. Thermal insulation materials are widely used and improving their properties or improving their production can therefore have a rapid impact on the efficient use of energy in …
The stress dependence of the electrical permittivity offers a convenient way of measuring pressure. This effect is suitable for static and quasi-static stress applications, where the conventional method based on the piezoelectric effect becomes inadequate. Although the principle of applying this effect for pressure sensing has been known for almost …
