Recently, with the development of Internet of Things (IoT) technology, interest in wearable devices is increasing. Flexible electronics undergo mechanical deformation in a variety of shapes and sizes. The substrate must be flexible and stretchable to prevent damage from these deformations. So far, soft materials such as silicone rubber and acrylic rubber have been mainly used as substrates for flexible devices. In this study, we introduce a stretchable substrate based on PDMS (Polydimethylsiloxane). It is manufactured by adding a material containing a vinyl group to control the crosslinking density. Various samples were prepared by controlling the amount of vinyl-based material added, and elasticity was measured. |
