1. An oscillating positive expiratory pressure device comprising:
a mouthpiece and a housing, wherein at least one of the mouthpiece and housing define separated first and second chambers having differential flow, pressure and/or temperature properties;
an energy harvesting component disposed between the first and second chambers and operable to generate electrical energy in response to the differential flow, pressure and/or temperature properties of the first and second chambers, wherein the first and second chambers define inhalation and exhalation pathways respectively;
a power storage device connected to the energy harvesting component and operable to store the electrical energy received from the energy harvesting component; and
an output operably connected to the power storage device.
