Woodworking-inspired mechanical metainterfaces show improved energy transport

Nature Electronics, Published online: 13 May 2026; doi:10.1038/s41928-026-01621-4 Interfaces are the main bottleneck for electrical and thermal transport through materials. Now, inspired by ancient carpentry joints, mechanical metainterfaces are developed that increase electrical transport and heat dissipation, with potential applications in electronics and power systems.
