Flexible thermoelectric module
Recent progress:Achieved large power factors of 154microW/mK2 in PEDOT:PSS-CNT in hybrid films, and over 600microW/mK2 in SWCNT-polystyrene composites.We developed p-type skutterudite materials whose heat resistant temperature reached 600℃. Towards the target of ZT=2, we successfully increased the power factor in the MnSi1.7/Si-Ag multilayer.The basic process of assembly was establishedin flexible thermoelectric modules.R&Ds to increase the figure of merit of polycrystalline clathrate compounds were performed.Large size silicide pellets (~φ100mm) were sintered, with deviation in in-plane electrical and mechanical properties < 5%..

Thermal Management
Recent progress:The heat transport amount 1.5kW under a 2m-distance and a 30cm-difference of ups and downs was achieved in loop heat pipe systems. As a new technology for enhancing the heat transfer performance, a motor cooling concept utilizing the phase-change was establish. Based on thermo-physical properties, new absorbents to absorption refrigerators for automobile use was discussed. Succeeded to reduced 65% of the system volume of the adsorption cooling system.
Thank you for your kind attention.
