Recently, printed materials and devices have attracted 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.

We recently, developed new quasi 2D-In2O3 semiconductor films and devices, which have high sensitivity and large transconductance. 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 tear’s 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, 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. Here, the strategy of detail

printed materials and devices formation in sensor applications will be discussed in terms of material chemistry, and hybrid processing.
