Challenges on Modeling Reliability of the Thermoelectric Generators

The growing environmental crisis and energy burden are drawing enormous attention towards thermoelectric structures and materials. The recent attention on thermo-electric materials and generators brought the pending researches on advance level. Comprehensive discussion has been done on recently proposed alternative designs, material competency and life-scaling models for improving longevity of the thermoelectric modules. During discussion distinction has been drawn between space and terrestrial devices and their obstacles. As part of deep space mission, to ensure the longevity of device, work is being done on mechanical stability and suppression of sublimation. While terrestrial devices are facing oxidation, thermally induced stress and mechanical degradation. In this paper we collected different literature and presented a model based on different laboratorial results. This precisely elucidates the role of reliability and current challenges, with an overview to understand potential parameters

Low Cost Embedded Copper Mesh Based on Cracked Template for Highly Durability Transparent EMI Shielding Films

Embedded copper mesh coatings with low sheet resistance and high transparency were formed using a low-cost Cu seed mesh obtained with a magnetron sputtering on a cracked template, and subsequent operations electroplating and embedding in a photocurable resin layer. The influence of the mesh size on the optoelectric characteristics and the electromagnetic shielding efficiency in a wide frequency range is considered. In optimizing the coating properties, a shielding efficiency of 49.38 dB at a frequency of 1 GHz, with integral optical transparency in the visible range of 84.3%, was obtained. Embedded Cu meshes have been shown to be highly bending stable and have excellent adhesion strength. The combination of properties and economic costs for the formation of coatings indicates their high prospects for practical use in shielding transparent objects, such as windows and computer monitors
