The study of conductive polymers has led us to create biosensors for the analysis of biological fluids, such as sweat. Sweat is a waste liquid, but it contains many biological molecules of interest (salts, glucose, hormones and neurotransmitters), which can act as indicators of an individual's state of health. Our study focused on the creation of a specific sensor for monitoring salts (Na, K), directly integrated into textile fiber in a shirt. In addition to the sensor itself, the t-shirt is equipped with an electronic device that performs measurements and sends data in real time to an app that can be installed on a smartphone.
The system we designed has the following advantages: real-time analysis of sweat, so there is an immediate indication of the person's state of health; complete wearability (the sensor is comfortable and this allows it to come into contact with the skin); ability to spontaneously absorb fluids (allows a simple and continuous acquisition of the sample); perfect integration with commercial textile products; low cost of the sensor, given the wide availability at low cost of raw materials. The goal is to develop the system, integrating the reading of other biomolecules of interest (reported in the abstract) contained in human sweat. This sensor can be applied to any garment, so it can be useful both in sports (competitive and non-competitive) and in the health sector.
