Researchers from the Agency for Space, Technology, and Research and the National University of Singapore have unveiled a remarkable microelectronic device. This device can function as a sustainable, high-performance “bit-switch”.
Imagine a little ball of magnetized material, but instead of the north and south poles pointing up and down like a regular magnet, they curl around in twisty circles on the surface of the ball. These are kind of what magnetic skyrmions are.AI and cloud computing uncover battery with 70% less lithium in record time technologies, such as ChatGPT has accelerated the need for sustainable computing solutions. These systems require vast amounts of data to be processed at lightning speeds.
This approach shifts data processing onto individual devices, alleviating strain on centralized data centers. However, the potential of edge computing is constrained by limited computing capacity and power constraints. The team identifies the need for innovative microelectronic platforms.At the heart of this research are skyrmions— minuscule magnetic whirls that exhibit remarkable stability and efficiency.
Remarkably, the team observed that switching between states in skyrmions takes 1,000 times less power than conventional commercial devices. They also found that more than two states could be achieved on a single device, implying enhanced performance without needing to scale the device down.
