Project : Self-startup sensor node platform
Purpose ● The main purpose of research project is designing universal energy harvesting platform that store the harvested energy from various energy harvester such as TEG, Piezo electric, Solar cell to super capacitor or Li-ion battery. The universal energy harvesting platform can deliver the energy to any sensor node and also store the harvested energy from any energy source that can act as universal battery.
Contents ● Designing the charger and dc-dc converter for universal energy harvesting platfrom
- The research of charger circuit which can harvest the energy from various energy sources such as TEG, Piezo-electric and Solar cell
- The designing charger circuit with low power relaxation oscillator, rectifier and boost converter
- The efficient storage and use can be realized as using both super capacitor and Li-ion battery or each as storage elements
- The designing hybrid type dc-dc converter for delivering the stored energy efficiently to sensor node
Expected Contribution ● The developing universal energy harvesting platform can supply the energy to the sensors developed from other research groups which have various specifications
