A new AA sized generator has been developed by Brother Industries that is capable of charging a connected AA battery using vibrations.
The new AA generator contains an electromagnetic induction generator and an electric double layer capacitor and is designed for devices that need small amounts of power to operate, such as remote controls.
Unfortunately, the current generator can’t power your larger gadgets, but a simple shake of your remote control may be all that’s needed to keep the batteries topped up.
How the Technology Works
The core technology behind this innovative generator is electromagnetic induction. When the generator is shaken, a magnet moves through a coil of wire, creating an electric current. This current is then stored in an electric double layer capacitor, which can quickly discharge the stored energy to power the connected device. This method is highly efficient for low-power devices, ensuring that they remain operational without the need for frequent battery replacements.
Brother Industries has currently prototyped the generator in both AA and AAA sizes. These sizes are particularly useful for devices that do not have a constant need to consume electricity but have a power consumption of around 100mW when in use. Modern remotes, for example, use between 40-100mW, making them ideal candidates for this technology.
Potential Applications and Future Developments
While the current iteration of the generator is not suitable for high-power devices like smartphones or tablets, it opens up a world of possibilities for low-power electronics. Imagine never having to replace the batteries in your TV remote, wireless mouse, or even certain medical devices that require minimal power. This technology could significantly reduce electronic waste and the environmental impact associated with disposable batteries.
Moreover, the concept of using vibrations to generate power could be expanded to other areas. For instance, wearable technology could benefit from this innovation. Fitness trackers and smartwatches that harness the energy from the user’s movements could become self-sustaining, eliminating the need for regular charging.
The new generators will be on exhibit at the Techno-frontier 2010 exhibition running from July 21 – 23rd, 2010, in Tokyo. This event will provide an excellent platform for Brother Industries to showcase their groundbreaking technology and potentially attract interest from other tech companies looking to integrate this solution into their products.
As the technology matures, we can expect to see improvements in efficiency and power output, making it feasible for a broader range of applications. Future developments might include integrating this technology into more everyday items, such as flashlights, toys, and even emergency kits, where a simple shake could provide the necessary power to operate.
In conclusion, Brother Industries’ new AA-sized generator represents a significant step forward in sustainable technology. By harnessing the power of vibrations, this innovative solution offers a practical and eco-friendly alternative to traditional batteries for low-power devices. As research and development continue, the potential applications for this technology are vast, promising a future where many of our everyday gadgets could become self-sustaining.
