  We devise a novel mechanism and for the first time demonstrate that the Higgs
model in particle physics can drive the inflation to satisfy the cosmic
microwave background observations and simultaneously enhance the curvature
perturbations at small scales to explain the abundance of dark matter in our
universe in the form of primordial black holes. The production of primordial
black holes is accompanied by the secondary gravitational waves induced by the
first order Higgs fluctuations which is expected observable by space-based
gravitational wave detectors. We propose possible cosmological probes of Higgs
field in the future observations for primordial black holes dark matter or
stochastic gravitational waves.
