Flexible, Disposable Cellulose-Paper-Based MoS<sub>2</sub>/Cu<sub>2</sub>S Hybrid for Wireless Environmental Monitoring and Multifunctional Sensing of Chemical Stimuli
Multifunctional
sensors responding to different chemical stimuli fabricated using
functional nanomaterials still remain a challenge because of the usage
of the same sensor multiple times for different sensing applications
and unreliable front-end processing of the sensing data. This challenge
is intensified by the lack of suitable techniques for fabricating
disposable sensors, which can be integrated into smartphones with
a dedicated application developed for each sensing application. A
novel MoS<sub>2</sub>/Cu<sub>2</sub>S hybrid grown on disposable cellulose
paper by the hydrothermal method is reported for its utilization in
sensing humidity, temperature, breath, and ethanol adulteration, wherein
the data can be wirelessly transmitted to a smartphone with the dedicated
application module for each sensing application. The sensor can be
utilized for a particular sensing application and then can be disposed,
avoiding the need for utilizing the same sensor for different sensing
applications, thereby increasing the accuracy of the sensing data.
The sensing mechanism of the fabricated sensor is explained for each
stimulus in terms of change in the transport properties of the MoS<sub>2</sub>/Cu<sub>2</sub>S hybrid. The development of such unique hybrid
materials for wireless disposable multifunctional sensors is a great
step ahead in flexible and wearable electronics having potential applications
in medical, security, Internet of things, etc
