Main content




This academic lecture focused on the technical advantages of thermoelectric materials in the fields of solid-state refrigeration and thermoelectric power generation, focused on the new possibilities brought by additive manufacturing (3D printing) to the design and preparation of thermoelectric material devices, and highlighted the research progress and interdisciplinary thinking of Professor Tang Jun's team in this direction.
The report starts from the basic principles of thermoelectric materials and points out that as a semiconductor functional material, it has outstanding advantages such as no moving parts, no noise, environmental friendliness, and easy control in realizing direct conversion of thermal energy and electrical energy. In recent years, with the growth of biomedical needs such as wearable medicine, local precise temperature control, and power supply for implantable devices, the miniaturization, flexibility, and customized preparation of thermoelectric materials have become key challenges. Against this background, Professor Tang Jun systematically sorted out the main research progress in the field of 3D printing thermoelectric materials at home and abroad, including the applicability of various additive manufacturing processes (such as extrusion printing, inkjet printing, laser-assisted deposition, etc.) in thermoelectric material molding, and how to optimize the ZT value and mechanical properties of the material through ink formulation, sintering process and structural design. In addition, it demonstrated a number of explorations carried out using additive manufacturing technology in recent years: First, the development of moldless, high-precision molding processes suitable for thermoelectric materials to achieve complex geometric structures that are difficult to process with traditional processes ； The second is to explore the integrated integration of thermoelectric devices and flexible substrates through co-printing of heterogeneous materials. ； The third is to preliminarily verify the feasibility of micro thermoelectric devices in biomedical scenarios such as local thermal management and wearable temperature control patches. The lecture particularly emphasized that promoting thermoelectric materials towards biomedical applications requires in-depth collaboration among multiple disciplines such as advanced manufacturing, materials science, physics and biomedical engineering. Additive manufacturing provides an important technical bridge for this. After the lecture, the participating teachers and students conducted exchanges on issues such as the biocompatibility of thermoelectric materials in living organisms, the output power and stability of microdevices, and the path from laboratory research to practical transformation.

This lecture provides a systematic perspective for understanding the intersection of thermoelectric materials and additive manufacturing, and also brings new inspiration for expanding their innovative applications in the biomedical field.
