KSJP10: Ultra-Low Energy Circuits for Distributed Sensor Networks (Smart Dust)

Brett Warneke
Brian Leibowitz
Mike Scott

The goal of this project is to develop an ultra-low energy integrated circuit that will form the core of a self-contained, millimeter scale sensing and communication platform for a massively distributed sensor network. The integrated circuit will contain an integrated sensor, an A/D converter, microprocessor, SRAM, communications circuits, and power control circuits. The IC, together with the sensors, will operate from a power source integrated with the platform.

KSJP26: RF Dust for Human Gestural Interpretation

Benjamin Cook

The goal of this project is to create an intuitive and natural interface mapping human expressions to the digital domain. Applications are limitless, but the focus of this project will be interpreting accelerations produced by human gestures as musical signals to allow realtime musical performance. Aquisition of these high resolution acceleration signals is achieved by square millimeter size MEMS sensing devices.

KSJP21: Algorithms for Position and Data Recovery in Wireless Sensor Networks

Lance Doherty

The goal of this project is to guide the development of sensor network theory. In this growing field, it is important to intelligently design experiments that explore the capabilities and discover the limitations of data collection from sensor networks. We seek to design quantifiable measures of algorithmic performance, apposite terminology, and paradigmatic perspectives to aid in the development of an information theory.

KSJP25: Ultra-Low Power Radio for Sensor Networks

Alyosha Molnar

Wireless sensor networks require cheap, very low power radios. We are exploring simple circuits in standard analog CMOS to provide this functionality. Although performance requirements are relatively easy, the transceiver should only consume on the order of 1mW. The challenge therefore is to provide relatively high transmitter efficiency even when radiating relatively little power, and to maintain a relatively selective, sensitive receiver while consuming as little current as possible. At a 1% duty cycle from a standard lithium-ion coin cell, this implies several years of operation...

KSJP12: Off-the-Shelf Distributed Robots (COTS-BOTS)

Sarah Bergbreiter

The goal of the CotsBots project is to use commercial off-the-shelf (COTS) components to build and deploy inexpensive and modular robots, which can be used to investigate algorithms and cooperation in large (>50) robot networks. Distributed robot networks have applications ranging from mapping and exploration to constructing complex systems. Work in BSAC is targeted towards providing a standard robot platform with a variety of modular sensor and actuator boards to test algorithms to solve these problems. In addition, we would like to explore the development of sensors that would...

Jason V. Clark
Corie Cobb
David Garmire
Raffi Kamalian
Tsuyoshi Koyama
Shyam Lakshmin
Jiawang Nie
Ying Zhang

Our goal is to create an efficient system-level analysis tool for the simulation and design of complex MEMS. The program is to be readily accessible, easy to use and extend, and capable of giving speedy results for complex systems, including static, steady-state, transient, sensitivity, and bifurcation analysis results. We will also support higher-level programs for design optimization and synthesis. We will incorporate state-of-the-art numerical libraries, as well as integrating new numerical techniques, such as improved model reduction methods. We will also build software to...
