  We introduce high-resolution solid-state imaging detectors for the search of
neutrinoless double $\beta$ decay. Based on the present literature, imaging
devices from amorphous $^{82}$Se evaporated on a complementary
metal-oxide-semiconductor (CMOS) active pixel array could have the energy and
spatial resolution to produce two-dimensional images of ionizing tracks of
utmost quality, effectively akin to an electronic bubble chamber in the double
$\beta$ decay energy regime. Still to be experimentally demonstrated, a
detector consisting of a large array of these devices could have very low
backgrounds, possibly reaching $10^{-7}$/(kg y) in the neutrinoless decay
region of interest (ROI), as it may be required for the full exploration of the
neutrinoless double $\beta$ decay parameter space in the most unfavorable
condition of a strongly quenched nucleon axial coupling constant.
