Weak and low-energy processes in particle physics, such as neutrino and Dark Matter interactions, require detectors with high sensitivity and large sensing volumes. In this Seminar I will present new sensors based on cryogenic Kinetic Inductance Detectors, superconducting resonant circuits cooled well below the critical temperature, whose main advantage reside in the reproducibility and scalability to large arrays of detectors. I will focus the Seminar on our activity on light detectors to search for Majorana neutrinos and to bulky detectors to search for neutrino coherent elastic scattering off nuclei.
