Hosiden has developed a micro non-contact charger using resonant inductive coupling technology, ideally suited for small devices such as wearable terminals.
By using resonant inductive coupling, the position dependence of the transmitter / receiver coil is reduced. This means a non-contact charging source is able to supply power up to a distance of 10 mm. Furthermore, multiple devices can be charged at the same time, making it possible to supply power to small devices with a high degree of positional freedom when compared to using electromagnetic induction.
The power receiver advances ultra-miniaturization with its miniature power receiving coil and small lithium ion battery incorporated. Because this device is non-contact, this enhances waterproofing.
The power transmitter and the power receiver will be able to support custom designs according to the application.
