Sejak beberapa dekad lalu, saiz dan kuasa peranti MEMS untuk kuasa kecil telah dicipta, seperti transduser dan sensor. Alat ini biasanya direka untuk berfungsi seperti bateri bagi menggantikan bateri sel kimia tidak praktikal .Selain itu, bateri sel kering tanpa amaran menyebabkan masalah serius masalah dalam aplikasi pemantauan keselamatan. Ini menyebabkan gelombang penelitian di bidang penjanaan kuasa dapat dicapai dalam menukarkan tenaga ambien (alternatif) menjadi tenaga elektrik. Beberapa kemungkinan sumber tenaga ambient(alternatif) yang, misalnya, tenaga panas, tenaga cahaya dan tenaga mekanik. Setelah tinjauan luas panen kaedah tenaga berpotensi, penukaran tenaga kinetik (getaran) kepada tenaga elektrik dipilih sebagai tajuk kajian ini. Getaran mekanik yang ada di kebanyakan sistem,. bekerja banyak difokuskan pada generator getaran-pemacu. Dalam bidang ini, induksi elektromagnetik sangat sesuai untuk penukaran tenaga mekanikal ke elektrik. Perancangan dalam sistem mekanikal yang memancarkan tenaga getaran sekitarnya untuk generator elektromagnetik adalah sangat penting. Tesis ini berkaitan dengan hubungan rekabentuk dan simulasi jumlah magnet digunakan dan kuasa yang dihasilkan untuk pembangkit mikro elektromagnetik . Magnet bergerak yang setara dengan sistem jisim getaran asas. Teori model seperti sistem angka-massa diberikan untuk menganggarkan ciri-ciri statik dan dinamik. Sistem ini dirancang oleh pemodelan dan simulasi kaedah unsur hingga menggunakan perisian Maxwell SV .Kajian numbor berangka juga digunakan untuk penilaian, analisis dan pengoptimuman rekabentuk elektromagnet dari generator mikro elektromagnetik.Tujuan analisis ini adalah untuk mencirikan magnet kekal dan kedudukan magnet daya Penghasilan (output) diukur dengan menggunakan hasil simulasi perisian Maxwell SV medan magnet induksi di gelung (coil) .Metodologi dan penemuan dalam kajian ini memberikan sumbangan sejumlah elemen ke bidang penjanaan kuasa MEMS, dan memberikan wawasan pembangunan mikro generator elektromagnetik. tesis ini tahun terakhir projek diakhiri dengan perbincangan mengenai prestasi generator mikro elektromagnetik dan cadangan untuk kajian lebih lanjut. _________________________________________________________________________________________ Over the past few years, there has been a huge reduction in size and power consumption of MEMS devices like transducers and sensors. These devices are usually designed to run on batteries the replacement of batteries is not practical. Moreover, batteries dying without warning cause serious problems in safety monitoring applications. That led to a surge of research in the area of energy harvesting. Sustainable power generation may be achieved in converting ambient energy into electrical energy. Some possible ambient energy sources are, for instance, thermal energy, light energy and mechanical energy. After an extensive survey of potential energy harvesting methods, the conversion of ambient vibrations to electricity was chosen as a method for further research. Since mechanical vibrations exist in most systems, many works focused on vibration-driven generators. In this field, the electromagnetic induction is well suited for the mechanical to electrical energy conversion. The design of the mechanical system that transmits the surrounding vibratory energy to the electromagnetic generator is a critical importance. This thesis deals with the design and simulation relationship of number of magnets be used and power generated for an electromagnetic micro generator. The flat spring and moving magnet are equivalent to a basic spring-mass system. The theoretical models of such a beam-mass system are given to estimate its static and dynamic characteristics. These flat springs were designed by modelling and finite element method simulation using Maxwell SV. Finite element method is also used for the analysis, evaluation and optimization of the electromagnetic design of the electromagnetic micro generator. The objectives behind this analysis are to characterize the permanent magnet and position of the magnet. Output power is estimated using the Maxwell SV simulation results of the magnetic field induced on the coil. The methodology and findings in this research provided a number of contributing elements to the field of MEMS power generation, and provided an insight into the development of an electromagnetic micro generator. This final year project thesis is concluded with a discussion on the performance of the proposed electromagnetic micro generator and suggestions for further research.
