There were as much as 1.5 billion of computer mice or more were using by the computer users worldwide as computer mouse serve as one of the basic input device for a personal computer. Due to the technology advancement, wireless or cordless computer mouse are more common than a wired mouse in recent years. However, the convenience of wireless mouse had brought some side effects along which is the usage of battery. A wireless mouse which can harvest ambient energy may be the potential solution for a wireless mouse to prolong its own battery life. Energy Harvesting (EH) is the process of capturing or converting external sources of energy and stored as small amount of electrical energy and commonly in the power level range of nW to mW. The usage of wireless mouse may have many possible source of external energy such as mechanical energy, light energy and thermal energy. In this project, an EH system integrated with wireless mouse was designed and experimented with selected energy sources for harvesting in order to prolong the battery life while reducing the number of disposal of used battery. The prototype built in this project was distinguished into two major parts which are mechanical design and electrical design. In mechanical design, the structure of a wireless mouse was modified and added with 3D printed parts while electrical design was made up of energy harvester, power management system components and power storage. The final tested result on the prototype had shown the possibility of harvesting energy by usage of the wireless mouse and prolong the battery life about 10% with some assumptions on the calculation. This project had unveil the potential of energy harvesting on wireless mouse which can reduce the overall power usage as well as the battery usage in the world.
