Abstract
Abstracts are not currently available in GtR for all funded research. This is normally because the abstract was not required at the time of proposal submission, but may be because it included sensitive information such as personal details.
| 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. |
