Magnetic Nanocomposites Enable Smaller Power Components for Computer Chips

Researchers are tackling a key challenge in shrinking computer chips: the power delivery components that feed transistors. While transistor scaling often grabs headlines, the inductors and other hardware that manage voltage and suppress fluctuations are equally critical—and notoriously difficult to miniaturize. A team has developed tiny magnetic devices called stripline microinductors using magnetic nanocomposites, a material approach that could dramatically reduce the size of these components without sacrificing performance. The work matters because as chips become more densely packed with transistors, the surrounding power hardware becomes a bottleneck for further size reductions and energy efficiency gains. By shrinking the power delivery system, the new inductors could enable smaller, faster, and more power-efficient electronics, from smartphones to data centers. The team’s findings suggest that magnetic nanocomposites may be the key to unlocking the next generation of compact chip power management.
