Have you checked what the local universities are working on? Are you tied to your area?
You should probably try to meet new people and network. Try to learn enough about their businesses, challenges, etc. As soon as you understand their challenges sufficiently, and you know of some solutions, suggest them. Eventually you will find something interesting you could do for them, and take it from there.
EDIT: of course, you should double check if there's nothing interesting you can do in your current company.
Also, network with the purpose to be helpful / find something interesting, not with the purpose to find another job. In case of the latter, people are likely to give you an introduction than to go in depth about what they are working on.
