Executive Summary : | Electromagnetic Radiation is identified as the fourth most crucial pollution in the world. It has been recognized as a slow poison. Electromagnetic interference (EMI) is a phenomenon that may occur when an electronic device is exposed to an electromagnetic (EM) field. Any device that has electronic circuitry can be susceptible to EMI. With the ever-increasing use of the electromagnetic spectrum and the more complex and sophisticated electronic devices, issues of EMI are attracting attention. When addressing EMI issues, consider a source, a path, and a receptor. The electromagnetic energy from the source propagates through the path and interferes with the operation of the receptor. Emissions are a measure of electromagnetic energy from a radiofrequency source. Immunity concerns the degree of interference from an external electromagnetic energy source on the operation of the electronic device. The device will be immune below a certain level of EMI and become susceptible above that level. The most common EMI problems are radio frequency interference and electrostatic discharge. IoT technology is the future where every device is connected to each other over internet. With the ever-increasing demand of smart devices, IoT will be trending worldwide in near future. IoT products use several different protocols and technologies, including Wi-Fi, Bluetooth, ZigBee, LORA, and more. In general, these technologies operate in different frequency bands on the electromagnetic or radio frequency (RF) spectrum. It has been observed that there has been 80 billion IoT wearable devices till the year 2020 and an increase of nearly 18% has been identified till May 2021. This project is aimed at mitigation of EM interference in wearable IoT devices with three different approaches: (a) Circuitry based approach: Simulation of a modelled wearable device and observe its effect on human body and as well as other IoT devices in its vicinity. (b) Material based approach: Rigorous laboratory testing of samples based on study and come up with the best material that can absorb the EM radiations without compromising communication. (c) Hybrid approach: Design and building up of a wearable IoT enabled device with the experimentally tested material in the vision of an optimized device which has no health hazard as well as environment friendly and above all serve mankind in the long run. |
