A Health Sensing Module Based on Plastic Substrates with Multi-plasma Treatments, Graphene Oxide and Nano Structures

In this project, a health sensing module integrated with a 2-dimensional chemical imaging sensor with high spatial resolution and a NH3 gas sensor with operation at room-temperature and low detection limitation by means of multi plasma treatment, graphene oxide and nano structures is proposed. This proposal will be worked out by 3 years with targets as listed below: 　 1st year: Plasma treatments will be used to improve ion selectivity of several ion sensing membranes including H+, Na+, K+ and Cl- ion for 2-dimensional chemical imaging sensor. With analog micro-mirror and pulse laser system, the spatial resolution of light addressable potentiometric system (LAPS) could be improved to the level of um. This achievement will be the leading performance of chemical imaging sensing field in the world. 　 2nd year：To optimize the spatial resolution of LAPS, graphene, graphene oxide and polystyrene (PS) nanospheres are planned to implement into the device structure by using of low temperature process including spin coating and inkjet printing. This developed nanosturucture can be also applied for resistive gas sensor with operation tempature at 25oC and lowest detection concentration of 100ppb. 　 3rd year：Roll-to-roll auto-injector system will be setup for the process of graphene, graphene oxide and polystyrene (PS) nanosphere. In the meantime, multi plasma treaments are investigated for high selectivity and low detecting limitation of gas sensor. By process integration design, a health sensing module with 2-D chemical image sensing and gas sensing array will fabricated.
