An Overview of the WIMS2 Research Center

The mission of the Center for Wireless Integrated MicroSensing and Systems (WIMS2) at the University of Michigan is to advance the design, fabrication, and breadth of the applications for sensor-driven microsensors and systems through research, education, and interactions with industry. These technologies include: micro and nanoscale fabrication, micromachined RF filters and resonators, packaging, power harvesting, low-power circuitry, and wireless interfaces with applications in biomedical devices, chemical and environmental sensors, and infrastructure monitoring. The applications' focus and interdisciplinary nature distinguishes WIMS2 from other university research efforts. The relevance of this research is shown by the 13 start-up companies and 69 patents the Center has generated over the past 14 years.

The biomedical device research topics include a family of neural prostheses aimed at treating disorders such as deafness, paralysis, epilepsy, and Parkinson's disease. The University of Michigan pioneered neural interface technology, which is now the focus for efforts worldwide. The Biomedical Devices Thrust also includes work on microfluidic systems for medical applications such as cell sorting and lab-on-a-chip applications. This research area leverages basic research in microfabrication, low-power circuits, and wireless and RF devices.

The Environmental Sensors Thrust is centered around an integrated gas chromatograph (GC) targeted at rapid gas analysis with sub-part-per-billion sensitivity. This research leverages technologies developed in the microfabrication area. The small scale of these devices enable greater portability, lower-power consumption, and faster response time than larger systems.

The Built Environment Sensing Thrust is developing microsystems to monitor the health of buildings and bridges, and the status of aircraft fuselages and naval vessel hulls. These devices are often connected together in wireless sensor networks that can communicate, measure, and analyze. Technology from the other research areas such as power harvesting, low-power consumption, and wireless connectivity are important enabling technologies for this effort.

The Wireless Interfaces Thrust undertakes basic and applied research in wireless interfaces for microsensor applications. Topics include CMOS RF circuits, miniature antennas, and sensor networking. The applications for this work are short-range biomedical devices and medium-range moderate data rate environmental sensing applications.

The Advanced Materials, Processes, and Packaging Thrust involves developing processing techniques for traditional and non-traditional MEMS materials, such as stainless steel, vacuum and wafer-level packaging, wafer bonding, assembly and interconnect technologies, mechanical protection of microsystems, and thermal management issues.

The aim of the Micropower Integrated Circuits Thrust is to greatly reduce the power requirements of integrated circuits used in microsystems. Topics of interest include low-power digital and analog circuits, new circuit and system architectures, system software, power management, and energy harvesting.
