Abstract

The continuous progress in electronics has led to disruptive innovations in the field of networking, towards the formation of a ubiquitous wireless network, which paved the way to the world of Internet of Things (IoT). The Internet of Things stands for a fully connected world, providing independent automated intercommunication between smart “Things”, which act accordingly, based on information they receive or perceive from surrounding environment. The term “Things” here refers to smart devices that exist in our world, being either a vehicle (smart car, bus, taxi or train), or a device in the house/building/city (heating systems, water distribution systems, even a fridge or a coffee machine) or in health care system (i.e. eHealth, in smart monitoring of patients, or gadgets such as smart watch or fitbits), just to mention some examples. In order for IoT to provide its utmost potential, the sensing technology implemented must provide highly accurate information. Therefore, there is a considerable amount of research being done in the field of sensing technologies, investigating multiple various techniques such as mechanical or electronic and optical.
