The NIHR Invention for Innovation (i4i) Programme is a translational funding scheme to advance healthcare technologies and interventions for increased patient benefit in areas of existing or emerging clinical need. i4i supports collaborative research and development projects that have demonstrated proof-of-principle and have a clear pathway towards adoption and commercialisation. The expected output is an advanced or clinically validated prototype medical device, technology or intervention. The aim is to de-risk projects and make them attractive to follow-on funders and investors. Back to research programmes.
