Fully Flexible Humidity Sensor with Fast Response and High Responsivity Based on rGO/MoS for Human Respiration Monitoring and Nontouch Switches.

Humidity sensors have been widely used to monitor humidity in daily life, agriculture fields, and so on. However, conventional sensors are not suitable for wearable devices because of their large dimensions and rigid substrates. Hence, we report a fast response, highly sensitive, and fully flexible humidity sensor on a PI substrate based on the composite material of reduced graphene oxide (rGO)/MoS, with a response time of 0.

A fast response and highly sensitive flexible humidity sensor based on a nanocomposite film of MoS and graphene oxide.

Graphene oxide (GO)-based humidity sensors are attracting widespread attention due to their high responsivity and low cost. However, GO-based humidity sensors generally suffer from slow response and recovery as well as poor stability. Here, we report a flexible resistive humidity sensor based on a MoS/GO composite film that was fabricated by mixing different volumes of MoS and GO dispersions with adjustable volume ratios.
