Influences of the ratio between pre-monomer and agent of PDMS to Pressure Sensing Property = Influences of the ratio between pre-monomer and agent of PDMS to Pressure Sensing Property

다국어 초록 (Multilingual Abstract)

The technology of wearable computing device has been developed fast. Especially, IoT (internet of things) technology would be cooperated with this device well, for example, wearable humidity sensor or temperature sensor or UV sensor was fabricated on fiber previously. Also PDMS is an elastic solid, structures made from PDMS are low cost, quick to fabricate, transparent, biocompatible, and flexible. In this work, we fabricated cylindrical capacitor which could detect pressure change. This cylindrical device was consisted of four layers, two nickel thin films for inner and outer electrodes and Polydimethylsiloxane (PDMS) layer with polyvinyl alcohol (PVA) at middle of that for dielectric material. The nickel thin film was deposited by RF magnetron sputtering and PDMS layer was dip-coated after mixing pre-monomer with agent differently. The ratio of pre-monomer and agent was utilized diversely. And then capacitance was measured by using HP 4284A.
