1. An injection device comprising:
a stopper comprising at least one electronic component;
an energy source configured to move relative to the stopper; and
a plunger head of a plunger rod, the plunger head configured to engage the energy source to move the energy source from a first position, where the energy source is electrically decoupled from the at least one electronic component, to a second position, where the energy source is electrically coupled to the at least one electronic component.
