Yes, wireless power transmission has been invented. It uses electromagnetic fields to transfer power without the need for physical cables. This technology is used in wireless charging for devices like smartphones and has applications in areas like electric vehicle charging and medical devices. While it’s a reality, there are efficiency and distance limitations that researchers are working to improve.
Efforts are underway to develop wireless power transmission for home appliances, but challenges such as efficiency over longer distances, safety considerations, and regulatory requirements need to be addressed before widespread adoption becomes feasible. While progress is being made, it’s difficult to predict a specific timeline for when wireless power supply for home appliances will become a practical and widely available technology.
Yes, you can buy wireless power switches that allow you to remotely control the power supply to your devices. These switches work by connecting to your home Wi-Fi network and can be controlled through a smartphone app or other means. They provide a convenient way to turn devices on and off wirelessly. Some popular options include smart plugs and smart power strips that offer wireless control and scheduling features.
Combining wireless charging and the power supply board can offer convenience and integration, but it’s not always necessary. While integrating both technologies can reduce clutter and streamline device design, it may also introduce complexities and potential points of failure. The decision depends on factors like the specific application, device size, efficiency considerations, and user preferences. In some cases, separate components for power supply and wireless charging might be more practical or efficient.
