Bi-Axial Stretchable Electrode Based on the Thin PDMS Substrate for the Biomedical Applications


Article Preview

PDMS(polydimethylsiloxane) is a flexible and biocompatible material and is widely used in bio- or medical-related fields. In this paper, we have developed the soft electrode to be stretchable bi-axially by using tissue-like soft material (PDMS). We have established the simple method to deposit the metal layer on the PDMS layer to be stretchable bi-axially and we have evaluated the electrical property according to the application of bi-directional stresses. This stretchable electrode can be extensively utilized in biomedical fields such as implantable electrode and wire at the flexion region or artificial skin.
