Bu çalışmanın temel amacı, Mikro-Elektro-Mekanik Sistemler (MEMS) tabanlı düşük güçlü elektronik sensörlerin ve kablosuz sistemlerin enerji ihtiyacını karşılamak üzere geliştirilen enerji hasadı tekniklerine odaklanmaktadır. Özellikle, minyatür jeneratörlerin tasarımı ve performansını artırmaya yönelik bir perspektif sunulmuştur.
Model, piezoelektrik özelliklere sahip bir MEMS sensörünü içermekte ve bu sensör, titreşimlere maruz kaldığında meydana gelen yerel ivme değişimlerini kullanarak elektrik enerjisi üretme yeteneğini değerlendirmektedir. Analiz edilen enerji hasadı sistemi, titreşen makineye bir uçta kelepçelenmiş bir piezoelektrik malzeme ve diğer uçta monta edilmiş bir denge kütle içermektedir Bu çalışmada, tasarlanan sismik enerji toplayıcısının belirli titreşim koşullarında etkili bir şekilde elektrik enerjisi üretebildiğini göstermektedir. SEA, sensörün geometrisini ve malzeme özelliklerini optimize etme potansiyelini ortaya koymuştur.

The primary objective of this study is to focus on energy harvesting techniques developed to meet the energy requirements of Micro-Electro-Mechanical Systems (MEMS)-based low-power electronic sensors and wireless systems. Specifically, a perspective is presented to enhance the design and performance of miniature generators.
The model incorporates a MEMS sensor with piezoelectric properties, and it evaluates the ability to generate electrical energy by utilizing changes in local acceleration induced by vibrations. The analyzed energy harvesting system includes a piezoelectric material clamped at one end to the vibrating machine and a balancing mass mounted at the other end. This study demonstrates that the designed seismic energy harvester can effectively generate electrical energy under specific vibration conditions. The Structural Eigenvalue Analysis (SEA) has revealed the potential to optimize the sensor's geometry and material properties.
