چکیده

امروزه با افزایش جمعیت، پیشرفت دانش و فناوری و در نتیجه بالارفتن نیاز به انرژی، استفاده از انرژی‌های نو و تجدیدپذیر از جمله مهمترین مسائل پیش رو محسوب می‌شود. از جملة این انرژی‌ها، انرژی اکوستیکی است. با توجه به تحقیقات صورت‌گرفته می‌توان دریافت که بررسی این امر به‌صورت تفکیک‌شده کمک شایانی به این طرح خواهد کرد. در این مقاله سعی شده است مروری جامع و کامل بر مبحث انرژی اکوستیکی ارائه شود. امکان استفاده از انرژی اکوستیکی ناشی از منابع آلودگی صوتی مانند موتورتوربوفن و هواپیما به‌منظور استفاده در ریزپردازشگرهای کم‌قدرت نظیر سمعک مورد مطالعه قرار خواهد گرفت. پس از شرح مکانیکی برداشت‌کننده اکوستیکی، به بررسی ساختار رزوناتورها، ترانسدیوسرها و انواع آنها پرداخته می‌شود. در پایان، به جهت کاربردی نمودن مباحث، نمونه‌ آزمایش‌های صورت‌گرفته بیان و دلیل به حاشیه رفتن این طرح بحث خواهد شد.
