Abstract

本申请涉及柔性电子的技术领域，具体公开了一种用于监测人体脉率的液态金属基柔性混合电子器件及制备方法。该器件包括由液态金属在橡胶基底上图案化形成的本征可拉伸电路，以及以贴片形式集成于其上的微型功能元件，整体由弹性体封装。制备方法包括：电路打印、热压图案、化学刻蚀、选择浸润、剥离转印、集成封装六个步骤，其关键是利用液态金属对铜的选择性浸润进行图案化，并利用半固化聚合物的特性进行软转印。本发明的器件得益于其本征可拉伸特性，能与人体皮肤共形贴附并同步形变，有效抑制运动伪影，从而在静坐、步行、跑步等多种状态下实现对脉率的精准、实时、长期监测。该制备方法工艺简单，成本较低，适于规模化生产。
