Résumé : |
The enormous growth in the utilization of electronic devices across the globe in various sectors like military, industrial, medical, etc. has generated a new form of pollution called electromagnetic interference (EMI) which cause the interference or malfunctioning of the electronic equipment and hampers its performance and functionality. Electromagnetic (EM) waves can also create health issues like cancer, headaches, sleep disordesr, brain tumors, fatigue, etc. This means there is a need to shield electronic devices. Development of EMI shield needs an understanding of EM waves, materials, the mechanism used, and measurement techniques. There are 2 types of shields: metal and textile, where metal shields suffer from various limitations which can be well addressed by the use of textile materials. The future EMI shield aims to achieve economy with comfortability which can drape to any desired shape and be manufactured with ease. Textile materials can offer these attributes as they are lightweight, durable, flexible, corrosion-resistant, comfortable, easy to cover, and cost-effective. |
