• Nanomaterial-based Devices

    We study the use of nanomaterials (including 1D carbon nanotubes--shown here--and 2D transition metal dichalcogenides, like MoS2) to enable a variety of high-performance and printed electronic devices.  With a truly 1D electronic structure, ballistic transport, and a ~1 nm diameter, nanotubes offer many advantages for electronics.

  • Printed Sensors from Nanomaterials

    The printing of sensors provides a low-cost and highly customizable approach for enabling countless applications in this Internet-of-Things (IoT) era. This includes biosensors, such as immunoassays, used for the targeted detection of disease-specific antigens for rapid diagnosis. The intrinsic sensitivity of nanomaterials, when appropriately printed into such sensors, can provide tremendous advantages over the state-of-the-art.

  • Carbon nanotubes monitor tire tread

    Using sensors made from printed carbon nanotubes, the tread depth of a tire can be monitored, electrically.  This low-cost solution is able to yield sub-mm accuracy in the tread thickness, all from electrical signals transmitted from inside the tire.  More details can be found in our IEEE Sensors Journal manuscript and in this story.

  • Taking electronics to new places with nanomaterials

    Our lab focuses on the integration of nanomaterials to enable a new generation of electronics, from advanced nanoelectronics to low-cost printed electronics.  Customization of form factor includes adapting electronic devices to different environments, from radiation harsh space to biological applications.

Franklin Lab

Our group is focused on improving the performance and functionality of nanomaterial-enabled electronic devices. This includes high-performance devices from low-dimensional materials such as 2D crystals, carbon nanotubes, and nanowires. Also included is the low-cost realm of printed electronics, which benefits from the incorporation of nanomaterials to enhance electrical transport over large printed features, among other application advantages. The primary drive of our research is to improve performance of, and/or expand applications for, electronic devices, including those with more custom form factors and/or functionality (flexibility, transparency, bioelectronic function, etc.).  A growing thrust in the lab is the application of ultrasensitive, cheaply processed nanomaterials to biosensing applications.
