3D-printed Bi2Te3-based Thermoelectric Generators for Energy Harvesting and Temperature Response

“…The devices were then tested by connecting the TEG to a Keithley 2400 instrument. The cold and hot end temperature was obtained by the thermocouples, and a thermally conductive silicone grease was applied in between the hot side and the TEG to minimize the contact thermal resistance …”

3D-Printed Soft Temperature Sensors Based on Thermoelectric Effects for Fast Mapping of Localized Temperature Distributions

“…The growing demand for the stable operation of electronic devices under external deformation has significantly advanced research into soft electronics. , These have been explored in various configurations for use in diverse environments and conditions, particularly for applications in human–machine interface sensing, motion tracking, and electronic skin. The critical role of temperature sensors in these applications is emphasized for real-time detection of target temperature changes, preventing thermal breakdowns or overheating to ensure device stability. − These sensors must rapidly detect localized, subtle temperature variations across a broad range, adhering perfectly to any surface shape to accurately monitor temperature changes and protect both industrial machines and skin-interfaced wearable modules from overheating, even under extreme conditions involving mechanical deformation. − Consequently, the development of temperature sensors that establish conformal interfaces with complex or changing shapes is crucial, demanding high sensitivity, lightweight, flexibility, and high cyclic stability to meet these challenges.…”
