Abstract: The present invention relates to a thermoelectric measurement system based on a liquid eutectic gallium-indium electrode, whereby thermoelectric performance can be measured with excellent efficiency and high reproducibility even without construction of expensive equipment, various organic molecules as well as large-area molecular layers can be measured, and various thermoelectric materials, such as inorganic materials and inorganic-organic composite materials, can be measured. In addition, non-toxic liquid metal EGaIn is used as an upper electrode, so the damage to even a substance of measurement in the form of a nano-level thin film can be minimized, and the measurement of thermoelectric performance can be performed on even nano- to micro-level organic thermoelectric elements. Therefore, the thermoelectric measurement system is widely utilized across the thermoelectric element industry.

Abstract: The present disclosure is related to structures for and methods for producing thermoelectric devices. The thermoelectric devices include multiple stages of thermoelements. Each stage includes alternating n-type and p-type thermoelements. The stages are sandwiched between upper and lower sets of metal links fabricated on a pair of substrate layers. The metal links electrically connect pairs of n-type and p-type thermoelements from each stage. There may be additional sets of metal links between the multiple stages. The individual thermoelements may be sized to handle differing amounts of electric current to optimize performance based on their location within the multistage device.
