We live in an extremely mobile and actually constrained world. From smartphones, smart watches, health trackers, Bluetooth headsets, hearing aids, to other wearable devices or smart ear devices, many of us are equipped with mobile devices from head to toe.

However, these mobile devices need to be charged and frequently charged. According to the frequency and purpose of using these devices, they may even need to be charged several times a day. This means that no matter where we go, we will always bring a charger, or we will have a charger wherever we go.

This is also why we say it is bound. The range of movement of electronic equipment is limited by the length of the charging line. This also makes wireless charging an inevitable development trend.

Wireless charging is a very obvious solution to the charging problems we face every day. This raises a question: What is preventing wireless charging from becoming the mainstream?

There are two factors: one is practical and the other is ideological.

Design barrier

First of all, from the actual factors, is the design itself.

The design challenges for wireless charging vary from device to device. For larger devices, such as cell phones, its challenges include charging efficiency and how the freedom of device (user) movement affects the wireless charging process. For smaller devices, such as hearing aids and smart ear devices, the design challenges include the placement and orientation of the devices during wireless charging, which is a problem for the more traditional coil-based wireless charging scheme.

Another challenge is the size of the wireless charging solution itself. After all, the coil is not very small in design. This brings another difficulty to the design of the equipment. How to make room in small equipment to install a coil with a large volume?

In order to meet the needs of wireless charging, engineers need to compare several indicators:

1. Is there any freedom in the placement direction of the equipment?

2. Is there any flexibility?

3. Is the charging mechanism efficient?

4. Does the equipment need to be placed in a very precise position to recharge?

There are a few conditions to be met here, but this challenge can be solved.

Wireless charging technology can solve the above challenges at one time, and its working principle is similar to Wi-Fi.

Change cultural concepts

The biggest obstacle to wireless charging is not design difficulties. Engineers can always find a solution, and they are also working on it. In fact, the biggest challenge is the user's concept and the inevitable question that needs to be answered: What is the relationship between wireless charging and me?

Imagine the most important technological achievements in the past few decades: computers, Internet, mobile phones, smart phones, iPod, etc. Before these products appeared in the market, did the public call for them? For most people, the answer is no. Because people don't know what they want until they don't know or have seen something with their own eyes. The same is true for wireless charging: most people do not know that they want wireless charging, or what benefits wireless charging has for them, because the concept has not been understood by the general public. Only when the public's ideas have changed can wireless charging really become the mainstream.

A World Without Chargers

Imagine that in the future, you don't need to carry a charger everywhere, just equipment.

The wireless charging sensor can be installed in every room of the home, on the desk, on the telephone in the conference room, at the local coffee shop or convenience store, at the cinema, at the railway station, at the bus station, at the airport, etc.

In other words, every place you want to go with Wi-Fi can have a wireless charging sensor, which can automatically detect your device (if it comes within range) and charge it remotely.

Wireless charging is a win-win technology. For equipment manufacturers, they can ensure that their customers' data acquisition will not be interrupted during use, thus obtaining a better user experience. After all, suppliers of healthy wearable devices do not want consumers to take off their devices to recharge, resulting in interruption of health data acquisition. For consumers, there is no need to worry about the battery running out and where to find a charger nearby.

About Wireless Charging Solution

Wireless charging solution intelligently provides adjustable power through wireless frequency band, similar to Wi-Fi router. Unlike earlier wireless charging systems, this solution can provide wireless charging to multiple devices within a certain distance.

The technology supports wireless charging in the near field (several millimeters), the middle field (0.6 meters to 0.9 meters) and the far field (up to 4.5 meters). By using RF-based antennas instead of more traditional coil-based solutions, ultra-small receivers can be realized.
