Study on the micro-heater fabricated using heat-shrink polymer; 수축성 고분자를 이용한 마이크로 히터의 제작 및 특성 연구

초록

This study presents a novel method for fabricating micro-scale heaters using the thermal shrinkage properties of polystyrene (PS) polymers. A cutting printer was employed to create patterns on transfer paper, which were then transferred to a PS substrate and filled with silver paste. By subjecting the substrate to a thermal shrinkage process at 180 °C, the PS and silver patterns contracted, resulting in microelectrode formation. The resistance of the microheaters was controlled by varying the silver paste composition, with values ranging from 1 to 10 Ω. Experimental results demonstrated a quadratic relationship between applied voltage and heating temperature for two microheaters with different resistances (1.7 Ω and 8.2 Ω). This simple and cost-effective approach, eliminating the need for photolithography, offers a promising avenue for fabricating various micro-scale devices.
