Wireless sensor network nodes and mobile devices are normally powered by batteries that, when depleted, must be recharged or replaced. This poses important problems, in particular for sensor nodes that are placed in inaccessible areas or biomedical sensors implanted in the human body where the battery replacement is very impractical. Moreover, the depleted battery must be properly disposed of in accordance with national and international regulations to prevent environmental pollution. A very interesting alternative to power mobile devices is energy harvesting where energy sources naturally present in the environment (such as sunlight, thermal gradients and vibrations) are scavenged to provide the power supply for sensor nodes and mobile systems. Since the presence of these energy sources is discontinuous in nature, electronic systems powered by energy harvesting must include a power management system and a storage device to store the scavenged energy. In this paper, the main strategies to design a wireless mobile sensor system powered by energy harvesting are reviewed and different sensor systems powered by such energy sources are presented.

Mobile devices have recently become powerful computing tools for aiding daily tasks. However, their batteries discharge quickly, even if they are not being used mainly because of the heavy computation tasks required by the multimedia applications that run on them. The swift turnover time on the battery life span is challenging as frequent charging is required to keep the device functioning. This is a major bottleneck because of the current energy optimisation crisis, user inconvenience due to constant charging of a battery and erratic nature of the electricity supply in some areas. In the current research project, the primary aim was to explore the energy harvesting technology innovation of radio frequency to wirelessly recharge the batteries of mobile devices. This implied an alternative way of charging the batteries of mobile devices without the need for a physical charger to connect to an electrical outlet. Energy harvesting, which involves making use of free energy from the atmosphere is the most innovative energy efficient wireless charging technology because mobile devices are constantly transmitting radio signals. Radio signals are initially received from the atmosphere through an antenna. Thereafter, these signals are converted using a rectifier circuit, from alternating current into direct current which is then utilised to recharge the battery of a mobile device. This research study adopted a mathematical modelling and simulation research methods. The model involved building an RF energy harvesting prototype. This prototype model displayed the limitations to be considered. The LTSpice simulation software was used to test the feasibility of combining diodes, capacitors and antenna type based on the limitations of the prototype model. The result of this research project demonstrates the building of a radio frequency harvesting circuit that can store a minimum load of 5mV that is required to charge the battery of a mobile device. Moreover, it has explained an alternative storage of the acquired energy using a supercapacitor compared to a mobile device battery.

Energi adalah suatu kebutuhan yang tidak dipungkiri lagi manfaatnya dalam kehidupan sehari-hari. Selain itu, pada dasarnya energi merupakan sesuatu yang kekal sebagaimana yang diterangkan dalam hukum kekekalan energi yang berbunyi “Energi tidak dapat diciptakan atau dimusnahkan, energi hanya dapat berubah dari satu bentuk energi ke bentuk energi lainnya”. Saat ini sudah banyak dilakukan penelitian untuk menciptakan sebuah energi terbarukan, seperti energi yang berasal dari air, angin, suara, nuklir, gas dll. Suara memiliki energi mekanik yang memiliki potensi untuk menjadi salah satu alternatif energi. Sebagai implementasi dari Hukum Kekekalan Energi, energi suara juga dapat dikonversi menjadi energi dalam bentuk lain seperti energi listrik. Proses konversi energi suara menjadi energi listrik ini memanfaatkan sebuah alat yang disebut piezoelektrik. Nilai frekuensi yang dihasilkan berada pada kisaran tertentu, dan nilai tertinggi berkisar diantara 760-780 Hz. Semakin dekat sumber suara, resonansi semakin sering terjadi dan tegangan yang dihasilkan Piezoelectric Transducer semakin besar. Jalan tol memiliki peran yang besar dalam mempercepat mobilitas dan laju pertumbuhan dalam berbagai aspek, khususnya ekonomi. Namun, berdasarkan dari berbagai sumber berita dan media elektronik lainnya mengabarkan bahwa sebagian besar jalan tol di Indonesia khususnya tol trans jawa dan tol trans sumatera masih memiliki lampu penerangan jalan yang sangat minim. Hal ini tentu saja bisa membuat semua pengguna tol harus ekstra hati-hati dalam melalui jalan tol khususnya pada malam hari. Oleh karena itu, kami menawarkan solusi berupa “Perancangan Sound Energy Harvesting Berbasis Material Piezoelektrik untuk Memanfaatkan Kebisingan di Sepanjang Jalan Tol di Indonesia Guna Mewujudkan Sumber Listrik Alternatif untuk Lampu Penerangan Jalan Tol”. Metode penelitian yang kami gunakan adalah studi literatur dan pengamtan langsung di lapangan.
