Gel Polymer Electrolyte Based On Sic:Pva Composites For Body Motion Sensor And Paper Based Application

Silicon Carbide (SiC) with and without adding Polyvinyl-Alcohol (PVA) were prepared and investigated both as an electrolyte solution and body motion sensor. The characteristics of SiC-based electrolytes have been investigated including pH, electrical conductivity, optical properties and FTIR pH and electrical conductivity have exhibited direct relation to each other for the studied electrolytes. From the optical properties of the solutions, the band gap values have been estimated around 3.2eV for the SiC-based composites. FTIR results confirm the preparation of SiC composition with several peaks. The electrolyte solutions (SiC with and without PVA composite) have demonstrated different voltages over a fixed period of time using two electrode cells to confirm the ability of these composites to work in the batteries. Paper-based devices have been also prepared using the casting method of these polymeric electrolytes on a cellulose paper. Papers have shown good stability in the optical images using SiC:PVA composite over SiC alone. The properties of these paper-based devices are also investigated. The electrical conductivity of these paper-based devices using Hall Effect measurements was examined. Pressure sensors, as well as the ability to use these paper devices as storage devices such as paper batteries, were examined.
