Disclosed is a delivery device for drugs and pharmaceuticals. A delivery device includes a dosing chamber for delivering a substance therefrom, a pressing device, and a thermal energy source. The thermal energy source is arranged to sufficiently change the temperature of a portion of the pressing device, thereby causing the pressing device to exert a pressing force on the substance to deliver the substance from the dosing chamber. The controller controls the delivery of the substance from the dosing chamber. Insulation insulates the material in the dosing chamber from the thermal energy source. [Selection] Figure 1A |
