발표초록 :

Recently, new sensing platforms in terms of healthcare and wearable applications by using printed materials and devices in hybrid manufacturing technology to enable low cost and new form factors. This process is also enable to apply new material and device processing, easily.

Today, I will focus on new quasi 2D-In2O3 semiconductor films and devices, which have high sensitivity and large transconductance for sensing applications. Based on these platforms, pH, glucose, and neurotransmitters could be detectable with high sensitivity. pH sensitivity was reached to over 60 mV/pH that was highly compatible with SiGe heterojunction bipolar transistors. For the glucose detecting application, we confirmed that the detecting ranges were covered within human tears glucose level (0.1 to 1 µM). Furthermore, our conformal device structures enabled to contact on highly rough surface as well as on an artificial eye for the smart lens applications. We also expended to the neuro chips for degenerative brain disorder applications, which were consisted with dopamine sequenced aptamers to get a specific binding of the small molecule. The conformational change of the aptamers with the binding of the dopamine could give the charge transfer upon the Debye screening length in physiological environments.
