Description
Summary:Modern gas detection systems have expanded into the monitoring of greenhouse gases, which are believed to cause global warming and are toxic to the human body. This demand has led to the development of numerous different discrete and distinct sensor technologies. A wireless sensing system is formed using the integrated arrays of field-effect transistors and sensors comprising graphene channels, silver nanowire electrodes, and interconnects with a wireless communication antenna. These carbon devices are highly flexible and can be transferred onto both planar and non-planar substrates, including papers, clothes, fingernails, and human skin. The printed wireless sensing antenna senses the gases by detecting the change in the signal produced by a change in sensor resistance.
