Abstract
In this work, the development of a new hydrogen sensor based on an interdigitated Pt-based electrode fabricated with semiconductor technology and conjugated polymers based on polycarbazole as selective receptor is described. The major novelty of this sensor is the ability to operate and measure at room temperature, which makes it an energy-efficient and safe solution and the mass fabrication of microelectrodes. The H2 sensor results demonstrate that the sensor is capable of measuring in a wide range of H2 concentrations from hundreds ppm up to low explosive level (4%) in air, containing different relative humidity, at room temperature with good linearity.
