Ease of fabrication

  • We are using the spin-coating or printing technique for making a sensor device

  • Compare traditional way of device fabrication

  • Show pictures of conductive inks and spin-coater

  • Mention the time and efficiency of making 1 devices compared to making a traditional metal oxide based devices (Eg. Vacuum deposition)

  • Printable electronics can achieve large area sensors and flexibility in the future (Eg. Wearable electronics, disposable electronics)

Organic based material for active layer

  • Possible chemical modification and formulations

  • Since the material is soluble in a solvent  capable of blending different materials to give nanocomposites for sensing (eg. Mixing with other high performance materials such as graphene or carbon nanotubes for sensing)

  • Formulation and chemical structures are patent protected, but similar precursor materials can already be sold in chemical vendors which allows us to do preliminary printing tests and formulations

  1. Show chemical structures of some common polymers if needed:
  2. PEDOT:PSS, PDQT, P3HT from these website:
Novelty 1
Novelty 2
          c. List of materials commercially available materials in Sigma Aldrich for possible formulations https://www.sigmaaldrich.com/materials-science/material-science-products.html?TablePage=19352647
  • Without the need of heavy metals for the active layer, more environmentally friendly

Novelty 3
  • Stability of OM materials.

  1. he electronics and environmental stability has been demonstrated using our Generation I and II prototype devices over the past year which shows that the stability of extraordinary
  2. The stability of the material is achieved by a series of patented procedures
  • Many of the organic based materials mentioned in section (b) or using conductive polymers in the past may give a high sensing performance but the stability was an issue
  1. OM materials has found a method for improving the stability of the organic matrix. The procedures are patent protected.
