Abstract: Primordial perturbations are a central target of cosmological observations, providing critical insights into the early universe and the theory of inflation. We propose using CMB B-mode polarization as a novel probe of curvature perturbations on scales $k\sim 1-100~{\rm Mpc}^{-1}$, a regime beyond the reach of traditional measurements. I will discuss the gravitational waves induced by primordial perturbations that affect CMB polarization, and the sensitivity of future CMB experiments to this signal.
