1. Going Wireless Might Be Surprisingly Easy! Don’t Give Up If the Structure Doesn’t Fit

Surprisingly Easy? Change the Structure with the Power of Ideas!

Wireless power transfer is a process that uses coils to transmit electricity through electromagnetic induction.

Many people may feel hesitant or find it difficult to work with coils, and in the case of wireless power transfer using flat coils, which are commonly used during this type of transfer, there may be difficulties in incorporating them into actual products.

We will introduce ideas to solve such concerns by exhibiting ABLIC’s wireless power transfer ‘demonstration device’.

Examples of Incorporating ABLIC’s Wireless Power Transfer into Products

The photo below shows a demonstration device for wireless power transmission and reception created using ABLIC’s wireless power ICs.

In wireless power transfer, it is necessary to match the inductance of the transmitter coil and receiver coil. The inductance values of the coils used in ABLIC’s wireless power transfer are as follows:

Transmitter 21µH
Receiver 26µH

The first step is to select coils that meet these values, and then consider a structure that can induce electromagnetic induction. It may be challenging to use a flat coil due to its shape when charging a long and narrow receiver unit, but in the demonstration device, electromagnetic induction is made possible by winding the coil in a spiral shape, achieving wireless power transfer.

Working with coils may be easier than you expect.

Just Place and Charge! Drop-in Charging!

With wireless power transfer, you can create interesting charging environments by simply placing devices on top of chargers or quickly inserting them into chargers.

The photo on the right shows the demonstration device for charging a pen-shaped device. The uniform magnetic field inside the coil enables charging once the pen is simply inserting into the dock. Multiple devices can be charged simultaneously as well.

It is easy to see how wireless power transfer can contribute to more user-friendly product designs.

 

2. Optimal for Waterproof Structure! Contactless Wireless Power Transfer

A Reliable Contactless Wireless Power Transfer System for Wet Environments

Products used in wet environments often require waterproof structures.
With connector-based power transfer, waterproofing the contacts and providing protection circuits against shorts is very crucial. Additionally, the inconvenience of plugging and unplugging the device may be a burden. Wireless power transfer can be useful to avoid such issues.

With wireless power transfer, it is possible to power devices without physical contact. It is also easier to create waterproof structures because there are no electrical contacts, making it ideal for beauty devices usually placed on vanities and washstands.

Wireless power transfer enables electronic circuits to be enclosed in resin or similar materials, ensuring complete waterproofing and providing users with a sense of security. Additionally, without connectors, the devices have more clean appearance.

 

Inside and Outside a Glass Case: Power Supply in Insulated Environments

Wouldn’t it be convenient if we could supply power from the outside to the inside of an aquarium through the glass?

While it is possible to incorporate wire harnesses inside the aquarium, it may not result in a clean and smart appearance. There is also the problem of wire harnesses being damaged by the aquarium’s edges.

With wireless power transfer, a power supply sent from the outside to the inside of the aquarium can be easily achieved using ABLIC’s simple wireless power transfer system.

 

3. The Joy of Contactless Power Supply

Many More to Discover! Examples of Wireless Power Applications

ABLIC’s wireless power transfer can be used in various applications and is ideal for charging wearable devices or systems that can transfer power when devices are in close proximity. It can be adapted to various wearable devices, such as wristwatch-type devices, small devices without charging connectors, card-shaped devices, and smart glasses (electronically controlled eyeglasses).

ABLIC’s Wireless Power ICs can easily configure the wireless power transfer because they are complete with proprietary power transmission and reception circuits and require no software development. They are ideal ICs for systems that need to perform non-contact charging and transmission power without being bound by standards.
