The microfabrication and soft-lithographic capabilities of our NBE facilities are aimed at thin and thick film (screen-printed) biosensors, printable electronic devices, micro total analysis systems (µ-TAS), polymeric and glass micro separation devices and screen-printed electrodes using the following equipment:
- UV Exposure System
- High resolution, cutting-edge 3D printer.
- High-precision semi-automatic screen printer (Model TF 100, MPM- Speedline Inc)
- Nikon video microscopes
- CAD graphic work stations
- Viscometer, centrifugal mixer
- Tension/compression test stand (stretch stage with digital force gauge)
- Photonic sintering
Printed electronics offers many new applications in diverse fields such as sensor arrays and energy harvesting devices. Printed electronics involves development of new materials in connection to various fabrication processes. Our expertise in printed and flexible electronics can be applied to a broad range of applications.
