Abstract:
Sweat is produced by the body naturally during physical activity and this fluid can be analysed in real-time to reflect the body’s hydration and electrolyte status. This paper reports a new type of organic disposable sensor pump that integrates sweat collection and sodium (Na+) ion sensing into cotton threads. This integration allows the sensor platform to be small, portable and wearable; thus allowing potential advantage to interface with the human body during field exercises enabling the provision of real-time data for immediate intervention. The sensor uses a sodium-selective Ion Selective Electrode (ISE) modified graphene oxide transducer intertwined with a thread pump. In this paper, we present the characterisation, synthesis and sensing data of this sensor.
