A thermoelectric device () and a method for manufacturing and using the same are disclosed. The thermoelectric device () includes a hot shoe () and a cold shoe () disposed about the hot shoe. A heat conducting member () formed of a thermoelectric material extends between the hot shoe () and the cold shoe () and generates electricity in response to a temperature difference therebetween. The hot shoe () is heated and expands at a greater rate than the cold shoe () does during operation. The structural and spatial relationship of the hot shoe () and the cold shoe () maintains the thermoelectric material of the heat conducting member () in compression during operation of the thermoelectric device ().

Thermoelectric device and methods for manufacture and use

A mass air flow sensor for an internal combustion engine is provided. The sensor has a pair of opposed nozzles. A converging nozzle has a first conical throughbore having a first throughbore axis, the first throughbore has first and second apertures, the first aperture has a diameter greater than the second aperture. The diverging nozzle has a second conical throughbore having a second through axis. The throughbore has third and fourth apertures, with the third aperture having a diameter greater than the fourth aperture. A first hotwire sensor positioned within the first aperture. A second hotwire sensor positioned within the second aperture.
