A thermal comfort device comprises a pair of selectively contractable piezo-electric diaphragms and a body sandwiched between the pair of diaphragms, the body defines a cavity and an opening, wherein, the piezo-electric diaphragms are adapted to be selectively contracted to flex outward, drawing air into the cavity, and to flex inward, forcing air out of the cavity, each of the piezo-electric diaphragms adapted to be selectively controlled by varying the voltage and the frequency, wherein the velocity of the air being forced outward from the cavity is selectively variable, and a thermo-electric device adapted to thermally condition air forced outward from the cavity by one of heating and cooling the air forced outward from the cavity, wherein the thermo-electric device is positioned at one of within the cavity and outside the cavity aligned with the opening.
