Wearable용 전도성 Ag paste에 의한 전극패턴 개발

Abstract

Currently, the printing electronics industry has made many improvements. In particular, the electronic device industry has grown a lot. and RFID(Radio Frequency Identification), MLCC(Multi-Layer Ceramic Capacitor) and OTFT(Organic Thin Film Transistor) etc. but it has reached the limits of industrial growth. Wearable, stretchable, and foldable devices open up new possibilities for development in the electronics industry by developing various materials and technologies. Wearable devices are being actively studied in fields such as healthcare, electronic paper, display, and electronic skin. In this study, instead of forming a wavy electrode pattern, a flexible Ag paste was prepared using Resin have a low Tg(Glass transition temperature). The Tg is the temperature at which the rubber becomes a state, and when the Tg is lower than the room temperature, flexibility and stretchability of the resin are different. The purpose of this study was to develop elastic paste suitable for electrode pattern of wearable device by using Binder with different Tg to analyze the difference of elasticity. As an electrode forming method, a screen printing method was used instead of a conventional semiconductor process. This printing method is suitable for mass production of devices, cost reduction, and high quality.
