I 北 京 印 刷 学 院 硕 士 论 文 ABSTRACT Flexible strain sensor are emerging as important applications for future soft robotics, portable consumer electronics, touch-on flexible display and health diagnosis because their excellent flexibility allows them working with irregular or rigid objects. The sensitivity of sensor have received growing attentions, however, it is still quite challenging to achieve high sensitive and large area sensor with simple, low cost and low energy processes. In this work, the large area stretchable conductors were made by embedding retiform silver nanowires(AgNWs) films in poly(dimethylsiloxane)(PDMS) with low cost and low energy processes. Besides, flexible capacitive pressure sensors and stretchable tension sensors based on flexible conductor were made. In order to improve
