Descripció:

Sweat has gained interest recently as a non-invasive source of relevant information about the health status of a subject. In particular, sweat loss and sweat rate are strongly related to dehydration which is a major issue for an athlete. There are multiple strategies to monitor these variables, but our proposal of study will be a chemiresistor sensor which consists in a volume-tunable substrate (paper) modified with a conductive nanomaterial (carbon nanotube ink) that produces a change in electrical properties (resistance) depending on the water absorbed (sweat volume) [1]. More detailed information can be found in the reference. The previous work focused on the optimization of the ink formulation, varying the type and quantity of carbon nanotube or the composition of the ink. The influence of the paper was not studied as they just used a commercial filter paper. We think the volume-tunable substrate plays a key role in enhancing the sensing capabilities of this sensor. The student will work on the design, fabrication and characterization of the sensors. Designing would require literature review and theoretical analysis. Fabrication include paper fabrication, ink preparation and sensor construction. Characterization of the sensors will be made at the laboratory with controlled volumes of artificial sweat. Once the characterization at the lab is completed, further integration in a wearable device for on-body measurements will be studied.
