Since the announcement, on February 2016, of the first direct detection of gravitational waves, the science that this new tool for observing the Universe has provided is staggering. Already proving its important role as a cosmic messenger. But this is only the beginning, our current level of sensitivity to the very faint ripples in the space-time allow us to sense only the strongest signals on the frequency region between few tens of Hz and few kHz. We are just starting to sense the bast amount of sources that are almost at our reach, we are inspired by the incredible science that soon will be possible. For this purpose there are already roadmaps to enhance the current second generation of detectors with the intention of increasing by two the design sensitivity of current generation. A third generation of detectors is already on the horizon to further increase the sensitivity on an order of magnitude. In each step also broadening the frequency band. In this seminar we will have an overview of where we are, we will look at the detectors and their limiting noise sources and then revise the technology upgrades expected for the enhanced second generation of detectors as well as the speculative upgrades of the third generation, keeping in mind the science case that will drive these upgrades.
