A distributed parallel resonance circuit is used to design a very compact low-pass filter with cutoff frequency 0.5GHz. The circuit has a section of transmission line shunt with an interdigital capacitor connecting with two low-impedance lines at both of its terminals. A finite transmission zero can be generated near the passband edge so that the filter has a sharp transition response. In addition, the stopband can be extended to more than 6GHz by properly choosing the structural parameters of the circuit. The measured responses match with the simulation quite well.

Single-use disposable biosensors are of importance in many applications related to health care, patient management, environmental monitoring, food and water quality analysis, personal safety and national security. Enzymatic biosensors using electrochemical detection techniques can be considered a platform technology. This study focuses on the development of high performance enzymatic biosensors based on this platform technology and their manufacturing methods. The applications of thick-film screen printing and inkjet printing techniques to manufacture the single-use, disposable biosensors are feasible and technically attractive. Experimental results will be presented to demonstrate the effectiveness of the printing technologies in the manufacturing of these biosensors with high performance characteristics.
