High-sensitivity and fast-response humidity sensor (Shinshu University Faculty of Engineering)
It is a capacitive humidity sensor that is 100 times faster than conventional commercial products!
This is a capacitive humidity sensor that combines polyimide with excellent heat resistance and chemical stability and MWCNT (multi-walled carbon nanotubes) + SWCNT (single-walled carbon nanotubes), achieving a response time on the order of 10 ms, which is 100 times faster than conventional sensors. Carbon nanotubes (CNT) have a nanoscale mesh structure, making them gas-permeable electrodes. It is also important that the upper electrode does not hinder the movement of gas molecules; for example, in the case of a humidity sensor that permeates water vapor, high hydrophobicity can be expected to enable a fast response. This technology improves response speed, sensitivity, temperature change suppression, and durability by attaching CNTs as the upper electrode to a thin film of polyimide, whose electrical properties change due to water vapor or gaseous chemicals, compared to conventional humidity sensors.
