Stroke is a leading cause of disability in the United States. Recovery from stroke is complex and ultimately limited by the brains limited ability to regenerate damaged tissue. Ideally, we would want to drive neurogenesis and angiogenesis in a stroke lesion to aid in recovery. We propose a multimodality platform for stimulating neurogenesis which simultaneously allows for electrophysiological recording of neurons in the lesion area after stroke. Our aim is to provide a paradigm for making complex substrates for nervous tissue. With various devices integrated, multiple functions can be...

The relentless pursuit of smaller, cheaper, and lower-power wireless electronics has driven the design of novel radio designs such as crystal-free radios, that o er a fully functional wireless node with minimal external components. At Berkeley, the Single-Chip Micro Mote (SCμM), a 3x2 mm, 4.2mg crystal-free 802.15.4 and BLE wireless SoC, was developed to make swarms of mm-scale microrobots a reality. This dissertation will begin by discussing SCμM in the context of system integration, including the challenge of accurate channel frequency tuning in the face of varying temperature and...
