Ultra-Miniaturized, Implantable and Wireless Data Acquisition and Actuation Systems

Authors: Ralph Etienne-Cummings (presenter), Jie Zhang and Adam Khalifa
There are many situation where substantial high-resolution data must be communicated over low bandwidth channels. These include ubiquitous distributed video, implanted high-density neural recordings, gastric monitoring ePills, and other such power constrained systems. To meet the communication specification of these systems, significant signal processing is required at the sensor in order to extract relevant information and/or to compress the data that must be communicated. Compressed sampling and reconstruction provide an efficient way to squeeze large amount of data into the narrow communication pipes. For example, we show that we can recover 100 frames of video from a single coded frame without motion blurring. We also show that the coded video can used for image enhancement, object recognition and other image processing even before reconstruction. On the neural recording front, we show high levels of compression that preserve both spike timing information and inter-spike signal integrity. This talk will show how compressed sampling and reconstruction can be used to can be used to communicate video and neural signals in these cases. Furthermore, we will show how ultra-miniaturized wireless cameras and implantable neural recording/stimulation devices take advantage of this method. Lastly we will discuss how this technology can be used to develop distributed, un-tethered sensing and actuation modules that can be injected through out the body to monitor a variety of biomarkers for personalized healthcare systems.
