In the domain of Machine-To-Machine (M2M) networks and sensing devices are fundamental for versatile context awareness applications, such as factory automation, home environment monitoring, and healthcare. Among different kinds of sensing quantities, gas sensing, e.g., e-nose systems are a big topic for applications in Indoor-Air-Quality (IAQ) monitoring and medical care. A numbers of technologies have been exploited to develop novel gas sensors which can offer miniaturized and low-power consumption characteristics. However, most gas sensor systems are limited by the dimensions of discrete sensor devices or the power consumption is still too large to combine with batteries or self-sustaining power harvesters for long-term usage.
