This paper presents a technology platform to fabricate micro thermoelectric generators (μTEG) with thin-film thermopiles. The combination of bulk and surface micromachining processes allows the integration of in-plane thin-film thermopiles in a device with a cross-plane heat flux. Heat flux guiding structures are used to maximize the temperature difference across the thermopiles. FEM simulation...

The complexity and challenges in noncontact temperature measurements inside microwave-heated catalytic reactors are presented in this paper. A custom-designed microwave cavity has been used to focus the microwave field on the catalyst and enable monitoring of the temperature field in 2D. A methodology to study the temperature distribution in the catalytic bed by using a thermal camera in combin...

The causes for surface defects in the con tinuouscasting process must be understood so that surface defects can be eradicated. The defects which were considered are presented and an approach to eliminate many of the in uencing variables using statistical hypothesis testing is presented. These methods show that only the thermocouple temperature readings within the mould are necessary to accurate...

This paper reports the fabrication and testing of Bismuth Tellurium (Bi2Te3) – Antimony Tellurium (Sb2Te3) based thermocouples using screen printing technology. In this study, screen printable thermoelectric pastes were developed and the transport properties of cured material were measured. The dimension of each planer thermoleg is 39.3 mm × 3 mm with a thickness of 67 μm for Bi2Te3 leg and 62 ...

In high speed cutting, the mean flank temperature is not likely to be less than that on the rake face, that is, the cutting temperature, as the undeformed chip thickness is very thin and of the same order of cutting edge radius. To measure the flank mean temperature, it is critically important to mount the artificial thermocouple properly in the workpiece. A new thermocouple mounting arrangemen...
