A Flexible Humidity Sensor with Wide Range, High Linearity, and Fast Response Based on Ultralong Na2Ti3O7 Nanowires

“…Low-dimensional nanomaterials have been broadly reported for humidity sensing through change of shape, − resistance, − capacitance, − microwave transduction, as well as optical properties . Among the sensing materials, one-dimensional nanowires (NWs) can be regarded as competitive candidates for humidity sensors due to their specific morphology features . For example, a large specific surface area can provide enough space for the adsorption/extraction of water molecules, which improves the sensitivity and shortens response/recovery time. , Besides, the enhanced length-diameter ratio of the nanowire brings sensor flexibility, and the adaptability on human skin enables a great wearing experience for the human body. , …”
