Description Discoveries:
The work funded through our "Spin waves to the rescue" has led to three ground-breaking key achievements on the road towards a spin wave (SW) based reservoir computing (RC) device: (1) Optimised device design for a SW-RC computing platform (via micromagnetic simulations); (2) Demonstration of the fundamental fabrication steps of an integrated SW-RC device; (3) Demonstration of a surface acoustic wave (SAW) based RC device at radio-frequencies.
Exploitation Route Taken Forward: We are in the process of securing the IP for the principles of wave-based neuromorphic computing, which we have developed during the tenure of the grant. Consequently, we are exploring the formation of a spin-out company with the help of Oxford's OUI and the divisional office.

Description Findings: The achievements have enabled us to start the process of securing IP and exploring the formation of a spin-out company. We are in the early stages of the process, but we receiving a considerable amount of help along the way.
