2001
Vibratory micromachined gyroscopes typically exhibit certain undesirable behaviors that impede the angular rate measurement, such as nonlinearity, cross-axis sensitivity, scale factor offset, and quadrature error. These errors have sources in both the mechanical and electrical ...

Design and Modeling of a Dual Mass SOI-MEMS Gyroscope

Ashwin Seshia
Roger T. Howe
Kristofer S.J. Pister
1999

This report discusses the design of a dual mass silicon-on-insulator(SOI) MEMS gyroscope. The main advantage of the dual mass gyroscope is the ability to cancel out common mode acceleration. The SOI MEMS process also provides several inherent advantages including increased out-of-plane stiffness, increased mass, and increased...

2002
Thumbnail-sized inertial measurement systems based on Micro Electro Mechanical Systems (MEMS) technology have been perceived as a breakthrough in the field of inertial navigation. However, even as micromechanical accelerometers have seen widespread commercialization, vibratory micromechanical gyroscopes...

Assembly and Molding Processes for Three-Dimensional Microfabrication

2002
Lithographic semiconductor microfabrication has been employed with great success for the manufacture of mechanical structures, achieving microscopic dimensions and great complexity at low cost. However, due to the inherently planar nature of the lithographic process, this technology is limited in its capability to produce three-dimensional structures. In this work, three strategies are presented for extending thin-film microfabrication into the...

Paul K. Wright
2003
This dissertation demonstrates that it is possible to build a useful and complex sensor and communication platform in the cubic millimeter scale using optimizations at the circuit, computer architecture, component, and system-levels to contribute toward this goal. The exponential size and power reductions in computation, communication, and sensing in recent years allows the integration of an autonomous wireless sensor node into volumes less than 16 mm^3. System architectures for...

2000
The goal of this thesis is to provide information on cubic inch autonomous sensor devices otherwise known as Commercial-off-the-Shelf Dust (COTS Dust). COTS Dust is capable of sensing and responding to environmental changes and communicating to other devices. This thesis is the compilation of my experience and knowledge in the design of COTS Dust and can be considered a guide for those who wish to design similar systems. Ultimately, its my wish that material provided within contains enough information for ...

Roger T. Howe
Richard M. White
2003
Commercial CMOS electronics and two in-house processes have been combined to establish a framework for making hybridized, milligram mobile robots. To demonstratethe capabilities of this framework, an 8.6 mm long, 10 mg, solar-powered prototype robot has been built. Dragging its tail end, the robot has demonstrated autonomous movement under its own weight and power, shuffling to the side a few millimeters and lifting its...
