Reverse heat flow with Peltier-induced thermoinductive effect
Kenjiro Okawa, Yasutaka Amagai, Hiroyuki Fujiki +1
The concept of "thermal inductance" expands the options of thermal circuit design. However, the inductive component is the only missing components in thermal circuits, unlike their…
Quantitative comparison of heat flow, guarded-heater and AC Harman methods for thermoelectric module efficiency
Kenjiro Okawa, Yasutaka Amagai, Norihiko Sakamoto +1
The evaluation of thermoelectric conversion efficiency remains challenging owing to the lack of internationally standardized measurement protocols. Commonly used techniques -includ…
Current comparator for both AC and DC ratio measurements with 10-8-level accuracy
Hidekazu Muramatsu, Yuta Kainuma, Hiromitsu Kato +11
Accurate measurements of alternating current (AC) and direct current(DC) ratios are fundamental to electric power metrology. However, conventional current comparators for AC and DC…
Accurate determination of thermoelectric figure of merit using ac Harman method with a four-probe configuration
Kenjiro Okawa, Yasutaka. Amagai, Norihiko Sakamoto +1
The ac Harman method has been used for the direct estimation of dimensionless thermoelectric figure of merit (zT) through ac/dc resistance measurements. However, accurate zT estima…
Large-scalable fabrication of improved Bi-Te-based flexible thermoelectric modules using a semiconductor manufacturing process
Kenjiro Okawa, Yasutaka Amagai, Hiroyuki Fujiki +7
Among the several flexible thermoelectric modules in existence, sintered Bi-Te-based modules represent a viable option because of their high output power density and flexibility, w…
