  The MICROMEGAS detector concept, generally optimized for use in accelerator
experiments, displays a peculiar combination of features that can be
advantageous in several astroparticle and neutrino physics applications. Their
sub-keV ionization energy threshold, excellent energy and space resolution, and
a simplicity of design that allows the use of radioclean materials in their
construction are some of these characteristics. We envision tackling
experimental challenges such as the measurement of neutral-current
neutrino-nucleus coherent scattering or Weakly Interacting Massive Particle
(WIMP) detectors with directional sensitivity. The large physics potential of a
compact (total volume O(1)m$^{3}$), multi-purpose array of low-background
MICROMEGAS is made evident.
