  Coherent neutrino-nucleon scattering offers a unique approach in the search
for physics beyond the Standard Model. When used in conjunction with
mono-energetic neutrino sources, the technique can be sensitive to the
existence of light sterile neutrinos. The ability to utilize such reactions has
been limited in the past due to the extremely low energy threshold (10-50 eV)
needed for detection. In this paper, we discuss an optimization of cryogenic
solid state bolometers that enables reaching extremely low kinetic energy
thresholds. We investigate the sensitivity of an array of such detectors to
neutrino oscillations to sterile states. A recent analysis of available reactor
data appears to favor the existence of such such a sterile neutrino with a mass
splitting of $|\Delta m_{\rm sterile}|^2 \ge 1.5$ eV$^2$ and mixing strength of
$\sin^2{2\theta_{\rm sterile}} = 0.17\pm 0.08$ at 95% C.L. An array of such
low-threshold detectors would be able to make a definitive statement as to the
validity of the interpretation.
