AB In this work two new different sensors are developed: a pH sensor and a temperature probe.The former is based on an electrodeposited polyaniline (PANI) layer employing sinusoidal voltagesand optimizing the deposition time (10–20 min). On the other hand, the temperature probe wasdesigned by taking advantage of the carbon nanotubes’ temperature properties. Both sensors werebuilt on sonogel-carbon electrodes, seeking cost effective devices. In both scenarios, the results weresatisfactory; the repeatability and reproducibility had values below 5%. Additionally, an excellent pHsensor selectivity was evaluated with the challenging interstitial matrix, prospecting an adequatefuture employment in real clinical samples.
