There are no in-situ electrolyte sodium sensors available in the marketplace, however there is a demand and use for them. An in-situ sodium sensor can be used to monitor bodily functioning in many applications like medical patient monitoring and athlete monitoring during workouts. Patients with cystic fibrosis attempt to monitor salt content in sweat to maintain homoeostatic body function, this sweat sensor would change the way those patients took care of themselves [1]. Sweat sensor samples were made using multiwalled carbon nanotubes (MWNT) and nylon 6. The MWNTs were functionalized on the nylon using cyclo-oligomeric calixarene [3]. In functionalizing the nylon’s surface with MWNTs the sensor can detect sodium ions present in human sweat [3]. Eventually, the collected data can be used to create a model to predict the responsiveness of the sensors to an electric current.
