Signaling of biochemical and bioelectrical information on the biological surface is important to get accurate, continuous bio-information. Recently, flexible invasive medical devices have been well developed with their mechanical stability for attaching sensors to complex body internal surfaces. Especially, they are attracting attention as implantable devices due to their conformability. In this study, we aimed to demonstrate various bio applications by realizing conformable electronics using polymer electronic components. The conformability of device platform was realized the two ways; one is the making ultra-thinness, the other is the adapting low Young’s modulus materials. We specifically demonstrate measurement in mapping bio-electrical signals on muscles, brains, and hearts and measurement in bio-chemical concentrations on the sweat, interstitial fluidic. Furthermore, we minimized the sensor elements by taking unique circuit schematic such as inductive coupling, self-powering, optical-information-transporting.
