Wireless sensor systems open up a wide range of new measurement applications in different fields of applications in medical, industrial and research environment. Typical applications of sensing, data processing and communication can be found in ambient assisted living projects and condition monitoring scenarios. Self-contained energy supply and wireless communication, which both enable a very flexible topology and a cost-effective implementation in existing environments, allow to cover these scenarios. Miniaturized wireless sensors, designed using advanced packaging technologies, can be placed where wired infrastructure is cost- and maintenance intensive. But these enablers are also limiting factors due to restrictions regarding communication range and data rates as well as energy density. In many applications, e.g. medical services, aspects like data security and system reliability are critical issues which have to be addressed by the hardware and software design. Therefore, methods and concepts for energy saving and increasing communication reliability have to be applied. This paper gives an overview of possibilities and limitations of wireless sensor systems and their optimization potential. Several public and industrial research projects have been realized at the Fraunhofer IZM.
