  A compact object with a mass $\mathcal{O}(1 \sim 1000) M_{\odot}$, such as a
black hole of stellar or primordial origin or a neutron star, and a much
lighter exotic compact object with a subsolar mass could form a non-standard
mini extreme mass ratio inspiral (EMRI) and emit gravitational waves within the
frequency band of ground-based gravitational-wave detectors. These systems are
extremely interesting because detecting them would definitively point to new
physics. We study the capability of using LIGO/Virgo to search for mini-EMRIs
and find that a large class of exotic compact objects can be probed at current
and design sensitivities using a method based on the Hough Transform that
tracks quasi power-law signals during the inspiral phase of the mini-EMRI
system.
