A biomedical sensor and sensor system for analysis of breath are disclosed. The biomedical sensor can include two layers arranged to swell or contract in a plane perpendicular to an axial direction while being restricted from swelling in the axial direction. The biomedical sensor includes resistance connections to allow measurement of the resistance of each layer and a combined resistance of both layers. The sensor system can include one, two, or three or more sensors, each having a pair of electrodes separated by a gap and one or more layers of composite material located within the gap. the sensor system includes resistance circuits configured to measure changes in resistance between the electrodes. A polypyrrole/polymethyl methacrylate/polyethylene glycol composite material and method of making the same are disclosed.
