Energy Harvesting for Piezoelectric using multi-device architecture with Parallel Charge Accumulation

In present era vibrational energy is a promising nonconventional energy source for portable and wireless electronic devices with extended lifespan, where less energy is required as energy source. Batteries are frequently used in these devices but charging is required to power the batteries just because limited lifespan of batteries, so replacement to be done in this field by researchers and piezoelectricity to be introduced as a promising source. The use of Piezoelectric materials to harvest power has already become popular. Piezoelectric materials have the ability to transform mechanical strain energy into electrical charge. This paper focuses on Piezoelectric devices as possible energy source and to research on multi-device connection and look for maximum energy generation. The scope of work will include, working for various configurations, connectivity etc to extract maximum energy from source. The research would consider -human walking- as energy source, hence a shoe mounted Piezo generator would be developed as energy source. The paper also considers to design an electronic circuit which can store the energy generated and even deliver the energy as a power Source. The emphasis would be on parallel charge accumulation which can enhance the charge generation. The paper will approach on the above postulates and will look for maximum power extraction from Piezo devices.
