Abstract

A microfluidic system includes a flexible substrate having a skin-facing surface and a back-facing surface; a microfluidic network at least partially embedded in or supported by the flexible substrate; a sensor fluidically connected to the microfluidic network, wherein the microfluidic network is configured to transport a biofluid from a skin surface to the sensor; and a capping layer, having a capping layer skin-facing surface and a back-facing surface, wherein the back-facing surface of the capping layer is attached to the skin-facing surface of the substrate. The flexible substrate is at least partially formed of a thermoplastic elastomer or a polymer configured to provide a high barrier to vapor or liquid water transmission.
