The flexible bio-potential electrode is gaining signifiacnt interest in wearable or implantable biosensors. Among many soft materials, polydimethylsiloxane (PDMS) is widely studied because of its good biocompatibility and elasticity. However, due to the nature of poor adhesion between an electrode material and PDMS, use of PDMS in the flexible electrode fabrication is limited. Recently, we had discovered a new approach which can create a strong adhesion between PDMS and metal. It enables the fabrication of a PDMS based flexible bio-potential electrodes for wearable or implantable sensors. As a proof of concept, a PDMS based flexible Ag/AgCl electrode was fabricated and characterized.
