In order to develop superconducting flux flow devices, we have measured the electrical characteristics of microbridges made from bilayers comprised of a conductive capping layer deposited on a very thin YBa/sub 2/Cu/sub 3/O/sub 7-/spl delta// film. In the flux creep regime, these structures show a low and quasi-constant depinning-to-critical current ratio and a high maximum vortex velocity. As expected from these features, the microbridges can be driven in the flux flow regime in the vicinity of T/sub c/. In the flux flow regime, surprisingly, the dynamic resistance is not an increasing function of temperature and shows a value which is in the range of the normal-state resistance at the onset of the superconductive transition.
