摘要： The present invention provides methods for purifying a layer of carbon nanotubes comprising providing a precursor layer of substantially aligned carbon nanotubes supported by a substrate, wherein the precursor layer comprises a mixture of first carbon nanotubes and second carbon nanotubes; selectively heating the first carbon nanotubes; and separating the first carbon nanotubes from the second carbon nanotubes, thereby generating a purified layer of carbon nanotubes. Devices benefiting from enhanced electrical properties enabled by the purified layer of carbon nanotubes are also described.

摘要： The present invention provides electronic circuits, devices and device components including one or more stretchable components, such as stretchable electrical interconnects, electrodes and/or semiconductor components. Stretchability of some of the present systems is achieved via a materials level integration of stretchable metallic or semiconducting structures with soft, elastomeric materials in a configuration allowing for elastic deformations to occur in a repeatable and well-defined way. The stretchable device geometries and hard-soft materials integration approaches of the invention provide a combination of advance electronic function and compliant mechanics supporting a broad range of device applications including sensing, actuation, power storage and communications.

摘要： 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.
