abstract = "The Internet of Things (IoT) represents a multi-layer
technology connecting diverse hardware (smart appliances,
smart gadgets, and wearable, biocompatible, and mobile
consumer devices) by middleware to the cloud of things
(CoT). It is changing how electronics interface with our
physical world in terms of sensing, information display and
communication. Gas sensors and sensor nodes are a vital
component of the IoT. Modern electronic systems are
flexible, transparent, biocompatible and wearable. Semiconducting metal oxides are earth
abundant multifunctional materials. Their multifunctionality stems from their complex and
widely varied electronic structure and properties. They include a wide range of band gaps,
high surface activity, and electrical properties making them the subject of continuous
research, especially in the form of nanoparticles for application in sensors, optoelectronics
and electronic devices. Metal oxides are stable materials, easy to synthesize and process. In
nanostructure form they show a wide range of enhanced properties, such as a suitable band
gap, conduction properties and confined conduction pathways for photoelectric electronic
devices. They are excellent candidates, in crystalline or amorphous form, for optoelectronic
devices, such as flat panel displays, solar cells, organic light-emitting diode displays (OLEDs)
and emerging flexible and transparent electronics, as they can exhibit high electrical
performance and excellent visible range transparency. The high growing demand for flexible
electronics requires low temperature and high-throughput synthesis of oxide thin films on
flexible plastic substrates. High sensitivity, fast response/recovery and good selectivity are
generally required of a good sensing material. Metal oxides still remain the first choice for
application in sensors, especially gas sensors due to their ease of fabrication, low cost, high
sensitivity, and stability. Some of their disadvantages are low selectivity and high operating
temperature. Over time commercially produced metal oxide gas sensors have reduced in size
being produced in different technologies, starting with tube-type sensors in the eighties of the
last century, through screen-printed sensors produced in the nineties and completing with
state-of-the art micro-electro-mechanical system (MEMS) sensors produced today.
Development of low cost, reduced power consumption and reliable sensing devices for the
detection of gases for environmental and industrial applications, especially at room
temperature remains a significant scientific and technological challenge.",
