In this review, the advances in radio-frequency (RF) /microwave chemical gas sensors using conducting polymers are discussed. First, the introduction of various conducting polymers is described. Only polyaniline (PANi), polypyrrole (PPy) and poly(3,4-ethylenedioxythiophene) (PEDOT), which are mainly used for gas sensors in RF/microwave region, are focused in this review. Sensing mechanism of the three conducting polymers are presented. And the RF/microwave characteristics and RF/microwave applications of the three conducting polymers are discussed. Moreover, the gas sensors using conducting polymers in RF/microwave frequencies are described. Finally, the the challenges and the prospects of the next generation of the RF/microwave based chemical sensors for wireless applications are proposed.

The Potsdam Wireless Testbed supports validation and evaluation of Wi-Fi radio stacks and wireless applications in environments with heterogeneous hardware. In contrast to simulators, wireless testbeds support the network stack validation with specific radio chipsets and radio signal propagations. Furthermore, wireless testbeds unburden programmers from manually updating software on nodes. Scheduled test-runs are executed automatically for a defined duration including compilation and deployment of the protocols and measurement scripts as well as collection of measurement results and log files. The testbed supports heterogeneous processor architectures and radio chipsets via internal cross compilation. The developer can overview the visualized results of its validation and therefore can focus on the code and the results. Next to the support of several device and processor architectures, the Potsdam Wireless Testbed is intended to support additional radio frequency ranges as well as mobile device.
