The neutrino mass scale is a relevant parameter of the theoretical framework beyond the Standard Model of particle physics. Cosmology constrains to 10meV the sensitivity required for future neutrino mass experiments, that means a huge effort of improving present instrumentation and technology. In this work we show a calorimetric approach for the direct measurement of the neutrino mass by means of 187Re single β decay and 163Ho electron-capture decay. An high sensitivity is achievable thanks to the high responsivity of superconducting microcalorimeters and their low intrinsic noise.
