Humidity responsible chitosan Fabry-Pérot resonator with photovoltaic cell |
| 초록 |
We introduced a tunable Fabry-Pérot resonator in the form of a MIM (metal insulator metal) multilayer using a chitosan hydrogel insulator. Since a chitosan polymer responds to humidity, the optical properties and thickness of chitosan layers change according to RH (relative humidity). This property allows to change the resonant wavelength of the resonator. This chitosan color filter can work as a humidity sensor when combined with a PV (Photovoltaic) cell. PV cells can transduce the input light spectrum into an electrical signal to show the surrounding RH. This sensor is simple to manufacture and will have almost zero-power consumption owing to its structure, which is useful for sensing RH in situations with low external power supply. |
