Within the last two decades major progress was achieved in experimental neutrino physics. This was only possible due to the constant development of new technologies in this field. Today a very broad progress of technologies can be observed, making possible neutrino experiments at very low energies (i.e. in the sub-MeV regime) until extreme high energies. In this lecture I will try to describe two examples, how new technologies developed within the last years. Both are mainly dealing with low energy neutrinos (i.e. below ≈ 1 GeV), however we will see how this technology may also be expanded to search for proton decays. This contribution will begin with a brief description of neutrino oscillations and the experimental status quo, followed by a short discussion about open questions in neutrino physics. Then the new technology developed for the search of θ₁₃ with the three reactor neutrino experiments will be presented, which started data taking in 2011. Finally I will discuss some aspects of a future project utilizing a very large, homogeneous liquid-scintillator volume.
