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...

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...

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 ...

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...

CMOS Imaging Receivers for Free-Space Optical Communication

2004
Free-space optical communication is an attractive alternative to radio communication for low power, long-range communication between small devices, primarily because utilization of shorter radiation wavelengths allows for more directional transceivers. At the transmitter, increased directionality allows for reduced transmission power because a given receiver will collect a larger fraction of the radiated energy. At the receiver, increased directionality allows for greater...

Evolutionary Synthesis of MEMS

2004
An evolutionary synthesis framework for Microelectrical Mechanical System (MEMS) design is presented. MEMS based technologies promise to bring a revolution to the world we live in just as the integrated circuit has done in recent decades; better design tools are critical to this revolution. More complex design objectives and constraints demand automation to generate successful devices. Genetic algorithms and other stochastic evolutionary synthesis approaches are used to design surface micromachined MEMS using...
