A new smart-lock technology has made long-range wireless charging a reality. The technology uses a combination of magnetic resonance and electromagnetic induction to charge the lock’s battery from a distance, eliminating the need for plugging in the lock or replacing batteries.
The smart-lock utilizes a charging pad, which can be placed near the door and connected to a power source. The lock, in turn, is equipped with a receiver coil that converts the magnetic energy into electrical energy, charging the lock’s battery wirelessly.
This technology allows for convenient charging and eliminates the need for regular maintenance of the lock’s battery. It also offers a level of security as the lock can be locked when the battery is low, preventing unauthorized access.
The technology can be integrated into different types of smart-locks, including keyless entry locks, biometric locks, and smart locks that are controlled by a smartphone app.
The smart-lock with long-range wireless charging technology is a game-changer as it eliminates the need for wires, cords, and regular battery replacement. With this technology, users will no longer have to worry about their lock’s battery running out, and this feature also makes it more convenient for people who are not able to access to the lock to change the battery.
Wireless charging that is long-range
Long-range wireless charging is a technology that allows for the charging of devices from a distance, without the need for direct contact or the use of cables. It utilizes various forms of wireless energy transfer, such as magnetic resonance or electromagnetic induction, to charge the device’s battery.
One example of long-range wireless charging technology is Wi-Charge, a company that has developed a technology that can charge devices from a distance of several meters using infrared energy. The technology uses a transmitter that emits infrared energy, which is then converted into electrical energy by a receiver on the device being charged.
Another example is Energous, a company that has developed a wireless charging technology called WattUp, which uses RF (radio frequency) energy to charge devices from a distance of up to 15 feet.
Long-range wireless charging has the potential to revolutionize the way we charge our devices. It eliminates the need for cables and direct contact, making it more convenient for users. Additionally, it could be integrated into various products such as smart-homes, cars, and public spaces making charging more accessible to the users.
However, the technology is still in its early stages and facing some obstacles, such as the need for a direct line-of-sight between the charging source and the device, and the potential impact on human health and safety. As the technology develops, it is expected that these issues will be addressed, and we will see more widespread adoption of long-range wireless charging in the near future.
The reality of RF is a lot less thrilling.
The reality of long-range wireless charging using RF (radio frequency) technology is that it is still in the early stages of development and has not yet been widely adopted. While some companies have developed RF-based wireless charging systems that can charge devices from a distance, the technology is still facing several challenges and limitations.
One of the main challenges is that the charging distance is limited and requires a direct line-of-sight between the charging source and the device. This means that the device must be in close proximity to the charging source and cannot be obstructed by walls or other objects.
Additionally, the efficiency of RF-based wireless charging systems is relatively low, and the power transfer is not as fast as other technologies such as Qi wireless charging or wired charging. The technology is still under development and is not yet available for consumer use.
Another issue is that wireless charging using RF technology is still not widely adopted, so it is not yet known if it will be safe for human health and environment. RF energy can penetrate human skin and tissue, and it is not yet clear how it will affect human health in the long term.
Overall, while RF-based wireless charging technology has the potential to revolutionize the way we charge our devices, the reality is that it is still in the early stages of development and faces several challenges. It will take some time before it becomes widely adopted and available for consumer use, and more research is needed to understand its potential impact on human health and the environment.
Instead, Alfred ML2 Smart Lock makes advantage of infrared.
The Alfred ML2 Smart Lock is an example of a long-range wireless charging technology that uses infrared energy instead of RF (radio frequency) energy. The technology uses a charging pad, which can be placed near the door and connected to a power source. The lock, in turn, is equipped with a receiver coil that converts the infrared energy into electrical energy, charging the lock’s battery wirelessly.
This technology allows for convenient charging and eliminates the need for regular maintenance of the lock’s battery. It also offers a level of security as the lock can be locked when the battery is low, preventing unauthorized access.
The use of infrared energy in this technology has some advantages over RF-based wireless charging. Infrared energy does not penetrate human skin and tissue, it does not pose a risk to human health as RF-based wireless charging does. Additionally, infrared energy transfer is more efficient and faster than RF-based wireless charging.
The Alfred ML2 Smart Lock is a great example of how long-range wireless charging technology using infrared energy can be integrated into smart-locks. It is a great solution for those who want to eliminate the need for wires, cords, and regular battery replacement while providing a secure way of locking and unlocking the door.
