Flexible and thin top-bottom-electrode hydrogen sensors for aerospace and battery applications

Kurzfassung

Hydrogen (H2) is undoubtedly the most popular future green energy carrier due to its harmless by-product, water. Thus, hydrogen becomes the most attractive energy carrier for light-weight and high safety requiring applications such as aerospace and power storage. However, as far as storage and transport of hydrogen in mobile applications are concerned, still the precautions must be taken, because H2 is colourless and odourless but flammable in air with very low ignition energy and combusts in air. The so-called Top-Bottom-Electrodes (TBE) combined with TiO2 sensing layer [Pt/TiO2/Pt] utilising Memristor sensor principle. Pt results in reduced Pt/TiO2 Schottky interface.
