چکیده

امروزه فناوری بی سیم به اندازه ای فراگیر شده که حذف آن از سیستم های ارتباطی و مخابراتی، آینده این سیستم ها را با ابهام مواجه می سازد. این ایده که تلفن های همراه، تَبلِت ها و یا حتی اتوموبیل های الکتریکی در آینده ای نه چندان دور قادر به شارژ هوشمند بی سیم باشند، بسیار هیجان انگیز است. از منظری دیگر البته، حتی تصور اینکه قطع کامل ارتباطات در بلایای طبیعی یا حادثه های انسانی چه فاجعه ای برای سامت انسانها و نیز عملیات نجات به بار خواهد آورد، دلخراش است. البته همه ی ما مدام با مقیاس بسیار کوچکتری از این معضل، یعنی نیاز به شارژ یا جایگزینی مکرر باتری تلفن های همراه و تَبلِت (لوح الکترونیکی) های خود، دست و پنجه نرم می کنیم؛ چرا که اساسا کارایی سیستم های ارتباطی بی سیم به عمر منبع انرژی آنها (یعنی باتری‌ها) محدود شده است. لذا، با توجه به زیرساخت های موجود در انتقال بی سیم اطلاعات و پیشرفت های اخیر در انتقال بی سیم انرژی، شاید اکنون زمان آن رسیده باشد تا برای انتقال همزمان قدرت و اطلاعات، آینده ای بیش از صرفا یک رویا متصور شد. فناوری انتقال همزمان بی سیم قدرت و اطلاعات (سویپت)، امکان ایجاد شبکه هایی قویتر با توان عملیاتی بالاتر و قابلیت انعطاف بیشتر را برای یک ارتباط مداوم واقعی فراهم خواهد نمود؛ البته، این مهم مشکلات پژوهشی و پیامدهای اجرایی بسیاری را نیز متوجه محققین می سازد. در این نوشتار، تاش گردیده تا با مروری بر آخرین پیشرفت های فناوریِ سویپت، کاربردهای آن، چالش های کلیدی و نیز راه حل ها در طراحی و کاربرد سیستم های مبتنی بر آن بررسی گردد.

چکیده [English]

Wireless technology is so widespread today that its absence from communication systems would put the future of such systems in uncertainty. The idea that mobile phones, tablets, or even electric vehicles would have the smart charging capability in the not-so-distant future, is very exciting. From a different perspective, however, the thought of the huge impact that a full power loss would have upon human safety, and rescue operations in human adversities and natural disasters, is harrowing. Indeed, all of us have to deal with a much smaller scale of this problem, that is, the need for recharge or replacement of our mobile phone or tablet batteries, on a regular basis; since the operation of these communication systems is essentially limited to the life of their energy source, i.e. batteries. Therefore, considering the infrastructure in place for information transmission and the recent advances in wireless energy transfer, it is perhaps time to conceive a future of more than just a dream for simultaneous wireless information and power transfer (SWIPT). As a key enabling technology for truly perpetual communications, SWIPT offers the potential to build networks with larger throughput, higher robustness, and increased flexibility compared to battery-powered counterparts; though undoubtedly, it also introduces significant research and implementation challenges.
