Implantable and Wearable Microelectronic Devices to Improve Quality of Life for People with Disabilities

Implantable microelectronic devices (IMD) and neuroprostheses are finding applications in new therapies thanks to advancements in microelectronics, microsensors, RF communications, and medicine, which have resulted in embedding more functions in IMDs that occupy smaller space and consume less power, while offering therapies for more complex diseases and disabilities. I will address the latest developments in key building blocks for state-of-the-art IMDs, particularly on the analog front-end, RF back-end, and power management. IMDs have been quite successful in neuroprosthetic devices, such as cochlear implants and deep brain stimulators. They have been recently approved for vision and are being considered for brain-computer interfacing (BCI) to enable individuals with severe physical disabilities to control their environments, particularly by accessing computers. Implantable BCIs, however, are highly invasive and should be used when there are no less invasive alternatives that would offer similar benefits. They can also be utilized as advanced tools for neuroscience research on freely behaving animal subjects. I will talk about the example of a smart cage, which can wirelessly power, communicate with, and track sensors implanted in or attached to small freely behaving animals. At the same time, novel minimally-invasive methods are being explored for individuals with severe paralysis to make the best use of their remaining abilities to control their environments. An example of such technologies is a wireless and wearable brain-tongue-computer interface (BTCI), also known as the Tongue Drive System (TDS), which enables individuals with tetraplegia to control their environments using their voluntary tongue motion.

Research Issues for Energy Efficient Cellular Networks

Abstract The rising energy costs and carbon footprint of operating cellular networks have led to a trend in addressing energy-efficiency amongst the network operators and regulatory bodies such as 3GPP and ITU. "Greening" the wireless networks is a vast research discipline that needs to cover all the layers of the protocol stack and various system architectures and it is important to identify the fundamental trade-offs linked with energy efficiency and the overall performance. In this talk, we identify four important aspects of a green networking where we would like to focus: defining green metrics, bringing architectural changes in base stations, network planning, and efficient system design. We begin with a brief discussion on energy efficiency metrics. Since Base Stations (BSs) consume a major chunk of input energy, we discuss the energy efficiency of BSs. Next we discuss energy efficiency from a network planning perspective, based on smaller cells for heterogeneous networks. For system design, we put a special emphasis on cognitive and cooperative techniques in order to realize energy efficient cellular systems. Finally we discuss some broader perspectives and possible future trends in realizing a green cellular network technology.

The Power Wall – Are We Scaling it, or is it Just Getting Higher?

At a plenary panel at ISSCC 2011, a number of leaders in the technology and circuit design arenas offered their perspective on how to accomplish a factor of 10x in power reduction over the next 5 years. No clear breakthrough solutions were ventured. Technology solutions such as FD-SOI combined with continued voltage scaling, concurrency and heterogeneity may ultimately result in a factor 10 if one works very hard. It is clear that larger reductions, sorely needed from an application as well as an environmental perspective, will require more innovative solutions. In this presentation, we will analyze a number of approaches that have the potential of doing so. More specifically, they remove the layers of inefficiency that still exist in most system implementations my gradually removing the margins – even to the point of designs operating with negative margins. This approach shifts the tasks of verification and validation from design-time to run-time, requiring systems that dynamically adapt to chances in the environment as well as the processing requirements. The talk will conclude with some speculation on ways of getting closer to the ultimate energy-bounds, such as neuro-inspired computing. Biography – Jan M.

Ultra-Low Power Platforms for Human Advancement

Enabled by pervasive wireless networking and ultra-low power technologies, so-called nanomorphic systems are now moving into the domain of the feasible. Sub-mm integrated wireless sensor nodes make it possible to directly observe and interact with biological cells in-vivo, opening the door for a broad range of applications in the domains of healthcare and well being. One application of particular interest is the domain of brain-machine interfaces, where sensor nodes directly observe neural activity in the brain, and use this information to restore function for people with severe neural disabilities such as stroke, spinal cord injury, ALS, epilepsy, etc. In this presentation, we will explore some of the ultimate bounds in miniaturization and energy reduction. We will focus on the realization of so called “neural swarms” – networks that exist in and around the human body to provide user-machine interfaces that are far more advanced that what we have today. The progress will be documented with results from our research group in the Berkeley Wireless Research Center, focusing on the realization of complete brain-machine interfaces. Biography – Jan M.
