Summary:
- This article discusses a quantum effect called the "spin-Seebeck effect" that could be used to power next-generation battery-free devices.
- The spin-Seebeck effect occurs when a temperature difference creates a spin current, which can then be converted into an electrical current to power electronic devices.
- Researchers believe this quantum effect could lead to the development of self-powered devices that do not require batteries, potentially revolutionizing the way we power various technologies in the future.
