Powder Metallurgy Characterization of Thermoelectric Materials for Selective Laser Melting

Batista N., El Desouky A., Crandall J., Wang S., Yang J., LeBlanc S., The George Washington University, US

Thermoelectric materials are semiconductors capable of converting heat into electrical energy. Traditional manufacturing of thermoelectric devices involves machining and assembly steps which limit device geometries, result in material loss, and introduce parasitic thermal and electrical [...]

Thermoelectric temperature sensors by printing with a simple office inkjet printer

Chae H., Jung M., Soum V., Lee J., Kim H., Kim T., Cheong H., Kim H., Kim T., Jeon S., Kwon O-S, Shin K., Sogang University, KR

Recently, printing temperature sensors have been significantly demanded in the paper electronics, such as electronic skin for robots, polymer chain reaction for DNA amplification. Here we present printing thermoelectric temperature sensors by using a simple [...]

Influence of CNT concentrations to polyurethane / multi-walled carbon nanotube composites on the thermoelectric performance

Wu Q., Hu J., The Hong Kong Polytechnic University, HK

In this paper, we investigated the possibility of applying polyurethane in thermoelectric application, and the influence of MWNT concentrations to polyurethane / multi-walled carbon nanotube composites on the thermoelectric performance. Polyurethane was used as the [...]

Impact of Ink Synthesis on Processing and Properties of Inkjet-Printed Silicon Thin Films

Drahi E., Gupta A., Blayac S., Lombez L., Jubault M., Benaben P., Ecole Nationale Supérieure des Mines de Saint Etienne, FR

Inkjet printing has a high potential for cost reduction in solar cell and thermoelectric industry. This study demonstrates that silicon thin films can be produced by inkjet-printing of a silicon ink followed by consequent drying [...]

Overview of Developments and Applications of Thermoelectrics Integrated with MEMS

Takahashi M., Omron Silicon Valley, US

We are faced with many energy and environmental problems such as the running out of fossil fuels, rapid increase in energy consumption by emerging-economy countries, global warming, etc. Against such a background, development of advanced [...]

Ye Q.L., Scheffler R., Kumari J., Leverenz R., NASA Ames Research Center, US

One-dimensional III-V compound semiconductor nanowires are an important class of nanomaterials that possess unique structures, remarkable properties, and great potential in various applications. InSb represents the smallest band-gap III-V compound semiconductor (0.17 eV at room [...]

Improving the High Temperature Thermoelectric Properties of Boron Cluster Compounds through Microstructure Control

Mori T., Nishimura T., Bando Y., National Institute for Materials Science, JP

The search for thermoelectric materials is being carried out with great intensity because of the huge possibilities for useful energy conversion of waste heat. There is obviously a particular need to develop materials which can [...]

Transport Properties For Carbon Nanotubes Under Hydrostatic Pressure

Chen F., Xue Y.Y., Stokes K.L., Wang H., Chu C.W., University of Houston, US

Multi-wall carbon nanotubes (MWNTs) were mixed with polystyrene (PS) by 20 wt%, which is close to the percolation threshold. Temperature (T) dependence of Seebeck coefficient (S) and resistance (R) for the sample (MWNT-PS) were measured [...]
