Understanding the primordial universe and the properties of the interstellar dust requires multifrequency observations of the polarization of the Cosmic Microwave Background (CMB) and of the polarized sky in the FIR. The challenging detection of the tiny target signal (from nK to tens uK) requires detectors unsensitive to cosmic rays, a modulation of the incoming polarization, large focal plane arrays, and cryogenic telescopes. From nanofabrication laboratories to the Atacama desert and the stratosphere: I will present my contributions to this exciting research field. A very long road from Cold-Electron Bolometers to the balloon-borne experiment PILOT to the Atacama Cosmology Telescope. From spinning photoresist on a Silicon wafer to plotting the results of astrophysical observations. From soldering resistors on circuit boards to building the AliCPT-1 telescope.
