This chapter describes two novel measurement systems that were developed recently in order to meet the requirement of rapid characterization of thermoelectric materials and devices. The first system was developed based on an innovative multifunctional probe that serves as electrical contact, temperature sensor and heater. The system enables rapid measurements of the Seebeck coefficient and electrical resistivity in less than 20 s with the precision and accuracy comparable to the well-establish thermoelectric measurement systems. In addition, it can be modified to determine the thermal conductivity with a random error of 12%. The second system is based on the impedance spectroscopy, which exploits the frequency response of a thermoelectric system for the understanding of electrical and thermal transport processes. Thermoelectric impedance spectroscopy provides direct measurement of zT and proves to be a suitable technique for high-throughput applications. Furthermore, with assistance of equivalent circuits, it is possible to determine all key thermoelectric quantities for thermoelectric materials and devices.
