  The influence of acceleration and rotation on spintronic applications is
theoretically investigated. In our formulation, considering a Dirac particle in
a non-inertial frame, different spin related aspects are studied. The spin
current appearing due to the inertial spin-orbit coupling (SOC) is enhanced by
the interband mixing of the conduction and valence band states. Importantly,
one can achieve a large spin current through the $\vec{k}. \vec{p}$ method in
this non-inertial frame. Furthermore, apart from the inertial SOC term due to
acceleration, for a particular choice of the rotation frequency, a new kind of
SOC term can be obtained from the spin rotation coupling (SRC). This new kind
of SOC is of Dresselhaus type and controllable through the rotation frequency.
In the field of spintronic applications, utilizing the inertial SOC and SRC
induced SOC term, theoretical proposals for the inertial spin filter, inertial
spin galvanic effect are demonstrated. Finally, one can tune the spin
relaxation time in semiconductors by tuning the non-inertial parameters.
