Invited Talk: Organic Transistors as Sensory Platforms for Health and Environmental Applications (IEEE Sensors Council Chapter)

April 22 @ 3:00 pm - 5:00 pm

Organic Thin Film Transistors (OTFTs) rely on polymer-based semiconductors, dielectrics, and conductive materials, often in conjunction with some inorganic materials such as metal nanoparticles, metal oxides, etc., to create tunable device behavior. OTFTs offer many benefits for implementation as sensory platform including solution processability, cost-effectiveness, ease of manufacturing, and superior compatibility to functional nanomaterials and biomolecules. These benefits have led to intense research in using OTFT as a sensory platform for chemical, biological, and environmental applications. In my talk, I will share some of our recent research highlights on implementing OTFT based non-invasive biosensor technologies for detection of metabolites and proteomic biomarkers. Target applications include monitoring body homeostasis and identifying early signs of pathogenesis for certain diseases including Parkinson’s disease and Alzheimer’s disease. More specifically, the talk will cover electrolyte gated FET (EGFET) platforms, and carbon nanoparticles based OTFTs. Amongst the sensors discussed, we will take a closer look at integrating functional nanomaterials within device framework to achieve the desired sensory response. Various device design and modeling strategies will be briefly discussed. Speaker(s): Dr. Ravi Prakash Virtual:
