FEA Simulation of RF Filter

Radio frequency micro structured coils are currently being developed in attempt to optimize the transmission and filtering features of electronics. They have a wide demand in next generation of communication devices and also bio medical applications.   The efficiency of these circuits plays important role in all aspects of the final devices like RF-Amplifiers, Filters, Modulators, or Bio Medical Sensors. Researchers at the NMDC are currently developing designs for the fabrication of high Q inductors using commercially available fabrication methods.  Numerical simulation of these designs demonstrates significant the quality factor improvements over state of the art MEMS technologies between the frequency ranges of 1 and 4 GHz.  Fabrication and testing of these devices is currently underway and will be released for publication late in 2008.

Portable Wireless Sensor Platform

Recent work by Dr. Robert Lindquist has lead to the development of a portable wireless pesticide monitoring platform.  The battery powered device uses liquid crystal sensors to monitor local concentrations of pesticide on site.   Information is then stored using a Motorola MSP430F1611 ultra low power micro controller for up to two weeks using.  Upon command, platform releases the information from a Nodric 24L01 wireless controller on a 2.4 GHz wireless network at a range of up to 50 m.
