Thermoelectric Fabrics In article number 2300092, Taeyoon Lee and co-workers depict, a bismuth telluride (Bi2Te3) thermoelectric fabric that detects a finger touch by generating an output voltage from temperature differences. Bi2Te3 nanoparticles, are formed inside the fabric, if there is a temperature difference, the fabric generates an output voltage. Therefore, the temperature difference can be detected by measuring output voltages of the Bi2Te3 thermoelectric fabric.
