Highly Stretchable Thermoelectric Fiber with Embedded Copper(I) Iodide Nanoparticles for a Multimodal Temperature, Strain, and Pressure Sensor in Wearable Electronics (Adv. Funct. Mater. 1/2025)

Abstract

Stretchable Thermoelectric Fibers In article number 2407759, Byeonggwan Kim, Taeyoon Lee, and co-workers develop a stretchable thermoelectric (TE) fiber-based multimodal sensor using the inorganic TE material copper(I) iodide (CuI). A robotic hand integrated with this innovative sensor is depicted grasping a human hand, demonstrating an emulation of the human skin somatosensory system. Temperature change, tensile strain, and pressure can be detected through distinct parameters of output voltage, electrical resistance, and capacitance.
