Abstraction: HZDR spin-wave reservoir computing advance compatible with CMOS fabrication

Key points:

HZDR team (project NIMFEIA) built a neuromorphic reservoir computer using spin waves (magnons) in a vibrating magnetic disk a few micrometers thick, avoiding the need for wave propagation between points
Different input patterns produce unique oscillation patterns in the disk; the system is time-sensitive so sequence changes alter outputs, enabling real-time pattern recognition
Unlike prior concepts requiring wave propagation from A to B, this uses standing resonant modes across the entire body (like sand patterns on a drum)
Demonstrated CMOS compatibility, enabling integration into standard semiconductor manufacturing lines with partners GlobalFoundries and Infineon
Target applications: edge computing on sensors, autonomous driving, IoT, pacemaker arrhythmia detection, wind turbine bearing fault detection
