These consumer electronic products are required to maintain its power for general operations. The power sources are mostly from secondary batteries to keep working. Although secondary battery can be reduced to the environmental pollution with the characteristic of repeated use, the various electronics companies are not designed to the same specifications, so that different manufacturers have different cable charger. When these electronic products are broken, these chargers will not be used any more, and that will results in many unused charger. The wasted charger is not only higher cost to a product, but also not environmentally friendly to the Earth. At present, people have wireless charging applications, such as PHS mobile phone charger and electric toothbrush charger. These methods avoid that the charging cable contacts the power terminal and have more integrated sense to a mobile device. The charger will waste the power when the product is not in use but the charger is in working condition if the charging is completed. That people have to manually disconnect the AC power also caused inconvenience. This thesis provides a smart wireless charger which can charge different types of handheld devices and go into sleep mode to save power consumption after the charging process is completed to meet the current world trends is to reduced carbon and to save energies.
