Q-Strip Disposable Sensor Prototype

The prototype “disposable sensor” is based on a liquid resistance measurement with paper as an insulator. The paper absorbs and measures the value of the conduction between the 2 electrodes as soon as it comes into contact with the liquid. During the first tests it turned out that the paper should not dissolve in the liquids. Using thicker paper (kitchen roll) gave the desired result. The paper is also reinforced by the 2 very thin electrodes that run along the entire length (80 cm to 180 cm).
At the moment I made strips of carbon strands with a thickness of 100μm, reinforced with absorbent paper from Nalys (this came out best from the tests when making QStrips) and an adhesive strip at the beginning to be able to attach the strip to the transmitter. This keeps the “system” hygienic and “handy” in use.
