Integrated microsystems that leverage the benefits of microfabricated sensors and actuators,  integrated circuit (IC) technology, and advanced packaging techniques are important for a variety of applications. In this talk, I will present three microsystems for advanced sensing applications.  First, I will present a standalone wireless and battery-less microsystem for high-performance strain-sensing applications in which stringent performance requirements are demanded to enable the early detection of catastrophic mechanical system failure. Next, I will present a biomechanical sensing microsystem consisting of a microfabricated, capacitive, ground-reaction sensor array and interface IC mounted in the heel of a boot for the detection of zero-velocity during stride.  This information is crucial to enhance the accuracy of inertial measurement units for personal navigation in GPS-denied environments. The third microsystem I will present is a miniaturized, autonomous, integrated measurement platform for complex dielectric permittivity measurement versus frequency (i.e., dielectric spectroscopy) in a broad frequency range from MHz to GHz. One application for this microsystem is directed at proteomics for high-throughput studies of protein structure and function to pursue scientific research or low-cost diagnostics with a portable platform. For each of these microsystems, I will describe how analog/mixed-signal/RF integrated circuit design is coupled with microfabricated sensors and advanced packaging techniques to achieve the performance requirements of the advanced sensing application.
