2007
Inexpensive MEMS gyroscopes are enabling a wide range of automotive and consumer applications. Examples include image stabilization in cameras, game consoles, and improving vehicle handling on challenging terrain. Many of these applications imposevery stringent requirements on power dissipation. For continued expansion into new applications it is imperative to reduce power consumption of present devices by anorder-of-magnitude. Gyroscopes infer angular rate from measuring the Coriolis force exerted on a...

Low Energy RF Transceiver Design

2007

The average consumer has relied upon bidirectional RF communication for phone and internet connectivity for years. These devices are either plugged in to wall outlets or rely on large batteries that must be recharged frequently. A new generation of deeply embedded, short-range wireless applications is emerging, fueled by the extreme reductions in cost and power required for sensing and computation afforded by CMOS and MEMS process advancement. The power consumption of wireless communication links, on the other hand, has not scaled down so dramatically. Short range wireless protocols...

An autonomous jumping microrobot has been designed, and its mechanical components have been fabricated and tested. Millimeter-scale autonomous mobile microrobots have potential applications in mobile sensor networks as well as search and exploration tasks. However, mobility is difficult at this scale due to rugged surfaces, obstacles and loco-motion efficiency. Jumping has been proposed as a locomotion method to overcome these challenges. The microrobot design has been divided into four components: energy...

RF Ranging for Location Awareness

2009

Wireless sensor networks provide an opportunity to improve performance in areas ranging from energy efficiency to industrial processes to scientific research. Many applications require awareness of sensor location, but autonomously determining device location has proven to be challenging. This localization problem can be divided into two parts: measuring relationships between nodes, and then using these relationships to estimate location. Most work on the first part has measured the RF received signal strength as a surrogate for range resulting in poor location accuracy. Several other...

Cortical Microstimulation for Neural Prostheses

2010

Brain-controlled prostheses have the potential to improve the quality of life of a large num- ber of paralyzed persons by allowing them to control prosthetic limbs simply by thought. An essential requirement for natural use of such neural prostheses is that the user should be provided with somatosensory feedback from the artificial limb. This can be achieved by electrically stimulating small populations of neurons in the cortex; a process known as cor- tical microstimulation. This dissertation describes the development of novel technologies for experimental neuroscience and their use...
