Transition-edge sensors (TESs) are outstanding calorimeters based on the steep superconductive transition of a metallic film. Among photon detectors, they belong to the top-tier positions for the high-energy resolutions and the low dark count rates. They are usually applied to detect electromagnetic energy from gamma-ray to visible and submillimetre wavelengths, but their use goes further. INRiM is presently involved in the development of TESs that pertain to different fields. In fact, TES capability of revealing massless or massive particles, while measuring their energies, can be applied in the quantum technologies, metrology and telecommunications, resolving photon signals from noise and counting them, as well as in the astrophysical and particle frameworks, from neutrino mass to multi-messenger astronomy measurements. For all these reasons, TESs are constantly under development in order to fulfil the more severe experimental requirements. The latest results obtained at INRiM on TES performances and applications will be presented.
