Disclosed is a pressure transducer including a body made of a material having a first coefficient of thermal expansion, a fluidic inlet and a fluidic cavity enclosed by the body in fluidic communication with the fluidic inlet. The pressure transducer further includes a strain gauge including a resistive element in operable contact with the body. At least a portion of the resistive element made of a material having a second coefficient of thermal expansion that is different from the first coefficient of thermal expansion of the body. Disclosed further is a pressure transducer including a filler body located in a fluidic cavity of the pressure transducer configured to reduce adiabatic thermal effects on a transducer body. Disclosed are systems and methods incorporating the pressure transducers described herein.

A pressure sensor has a stem in which a pressure introduction hole into which a pressure medium is introduced and a diaphragm deformable according to the pressure of the pressure medium are formed, and a strain detecting element which is arranged on the diaphragm via an insulating film and being configured to output a detection signal according to the deformation of the diaphragm. The strain detecting element is configured to have a portion made of polysilicon. A low doping layer having a higher electrical resistivity than polysilicon and a higher crystallinity than the insulating film is arranged between the insulating film and the strain detecting element.

An aerosol delivery device includes a housing structured to retain an aerosol precursor composition, and an aerosol production component. The aerosol delivery device includes processing circuitry configured to operate in an active mode to control power to the aerosol production component to produce an aerosol from the aerosol precursor composition. The aerosol delivery device also has a user interface including a pressure-sensitive surface and a pressure sensor. The pressure sensor is configured to measure pressure, and generate a corresponding signal, as a function of force applied to the pressure-sensitive surface. The processing circuitry is also configured to receive the corresponding signal and identify an operation based on a level of the corresponding signal and thereby an amount of the force applied to the pressure-sensitive surface. The processing circuitry is also configured to execute the operation in response to the corresponding signal and thereby the force applied to the pressure-sensitive surface.
