Paper presents usage of viscoelastic material in the body of turning tool holder in order to damp the vibrations in the turning process. The standard approach to designing is the strength and stiffness based designing resulting from static material properties. However, each dynamically loaded structure is the subject of vibrations. Thus the dynamic material properties (damping measures) are of equal importance as vibrations are a part of the machines and devices performance. Their occurrence cannot be prevented be...

Paper analyses the principles and industrial applications of thermoelectric generators and energy harvesting devices in their almost 200-year history, e.g. from first documented application in 1840 till the current applications focusing on thermoelectric generators using waste heat from fireplace furnaces. Moreover, the energy harvesting devices as low power applications are involved in the paper. Applying the thermoelectric generators into existing products gives the managers an ability to innovate, be unique and...
