Impedance of PEDOT over time
I was introduced to this project by my laboratory PI, Dr. Natalia Pexioto. The task was to record data from various screen printer electrodes, each covered with different amounts of PEDOT. To measure how the PEDOT will react over time, we ran CV and EIS continuous over my time. A 32 channel CH Instrument was to run the test, the setting for the test was programmed with Macro code.
Cellular to RF Replacement
My first task as a laboratory assistant was to aid a fellow assistant replace cellular modem with an XTend RF module. The project was to improve a cellular connection to a less expensive alternative. The setup included a water-sensor located in the GMU-Fairfax campus, the data was from the sensor was saved in data logger with had had the capability to be connected to a wireless modem, the data logger can only be accessed by a program in the user’s computer. Our main concertation was to remove the cellular modem connected to the data logger, the Xtend modem was selected, and the new modems setting were changed to match the specification of the overall project, in order to reduce power consumption.
