Development of rain drop energy harvesting prototype testing kit / Mohammad Amin Nazrin Mohammad
Penuaian tenaga boleh menjadi penyelesaian kepada salah satu daripada masalah utama oleh peranti bateri kerana ia mempunyai sifat bekalan tenaga tanpa had. Alat-alat penuaian tenaga boleh menukar tenaga terbuang dari persekitaran kepada kuasa elektrik. Dengan menuai tenaga dari alam sekitar, sensor boleh digerakkan secara berterusan. Dalam projek ini, piezoelektrik yang digunakan untuk menukar tenaga mekanikal kepada tenaga elektrik daripada sumber-sumber titisan hujan ialah Polyvinylidene fluorida, PVDF. Projek eksperimen ini dijalankan ke atas piezoelektrik dan profil titisan hujan. Apabila titisan air hujan jatuh ke atas piezoelektrik, ia akan bergetar. Bahan piezoelektrik PVDF ini dapat menangkap tenaga kinetik dan menukar ke elektrik. Untuk menangkap tenaga kinetik dari dari titisan air hujan, adalah sangat penting untuk memahami faktor-faktor yang menyumbang kepada tenaga kinetik air hujan seperti kelajuan titisan air ketika jatuh dan saiznya. Projek ini bermula dengan kajian teori penuaian tenaga dari titisan air hujan dan transduser piezoelektrik. Persediaan eksperimen dan keputusan telah dibincangkan. perbandingan voltan yang dihasilkan daripada dua mekanisme PVDF yang berbeza dengan dimensi yang berbeza juga dibincangkan. Dalam projek ini, voltan yang paling optimum dihasilkan adalah 8.4822 V iaitu dari struktur jambatan dengan dimensi piezoelektrik panjang 60mm, lebar 4 mm dan tebal 25 μm. _______________________________________________________________________________________________________ Energy Harvesting can be a solution to one of the key problems by battery powered devices because it have unlimited nature of the energy supply. Energy harvesting devices can convert wasted energy from environment to electrical power. By harvesting energy from the ambient environment, the sensors can be powered continuously. In this project, the piezoelectric material which is Polyvinylidene fluoride, PVDF is used to convert mechanical energy to electrical energy from raindrop sources. This experimental project is conducted on the model of a piezoelectric energy harvester and the profile of the kinetic energy of raindrops on them. When the raindrop impact on the piezoelectric material, it will vibrate. This PVDF piezoelectric material is able to capture this kinetic energy and convert it into electricity. To capture kinetic energy from rain, it is very important to understand that factors that contribute to the kinetic energy of rain such as terminal velocity of falling droplet and drop size. This project starts with theoretical studies of the rain drop energy harvesting and the piezoelectric transducer. The experimental setup and results are discussed. Comparison of output voltage of two different PVDF mechanisms which are with different dimension is also included. The thickness and the length of the piezoelectric can be affect the energy produced. In this project, the most optimum voltage output is 8.4822 V that is from bridge structure with the piezoelectric dimension of 60mm length, 4 mm width and 25 μm thick.
