I doubt that a microprocessor will be able to operate solely off ambient RF, but I could see a low power microprocessor being combined with this and a betavoltiac for impressively long life. Using this with the new diamond battery that they have in the labs at the university of Bristol would enable the creation of wireless devices that last over 5000 years.
