Abstract

Multifunctional sensors responding to different chemical stimuli fabricated using functional nanomaterials still remains a challenge due to the usage of same sensor multiple times for different sensing and unreliable frontend processing of the sensing data. This challenge is intensified by the lack of suitable techniques for fabricating disposable sensors which are integrated to smartphone with a dedicated application developed for each sensing. A novel MoS2/Cu2S hybrid grown on disposable cellulose paper by hydrothermal method is reported for its utilization in humidity, temperature and breath sensing and ethanol adulteration wherein the data can be wirelessly transmitted to smartphone with dedicated application module for each sensing. The sensor can be utilized for particular sensing and then can be disposed avoiding the need for utilizing the same sensor for different sensing thereby increasing accuracy of the sensing data. The fabricated sensor was further utilized for real time diagnosis of hydration level of human body using breath. Detailed sensing mechanism is explained for each stimuli in terms of change in the transport properties of MoS2/Cu2S hybrid. Development of such unique hybrid materials for wireless disposable multifunctional sensor is a great step ahead in flexible and wearable electronics having potential applications in medical, security, Internet of things etc
