BSN Platform Tutorial 2011

Guang-Zhong Yang and Benny Lo
Imperial College London

Wednesday, May 25, 2011.

The aim of the day-long tutorial is to provide an introduction of the BSN concept, the associated technologies and the theories behind the concept to researchers and academics who are interested is the BSN related research. In addition, the tutorial will include a number of hands-on sessions to give the participants an opportunity to implement and gain some first hand experience in building BSN applications using the BSN development kit. Each registered attendee will receive a BSN development kit for free. Cost for this day long tutorial is $400.

Ensuring Safety, Sustainability and Security in Body Area Networks

S. K. S. Gupta and T. Mukherjee, Arizonal State University
K. Venkatasubramanian, University of Pennsylvania

Wednesday, May 25, 2011.
8AM-12 Noon

A major concern with using BANs however is the potential hazard to the environment (human body) from interruptions in and side-effects of its operations. We view the challenge of addressing the potential hazards as the satisfaction of three properties: Safety (i.e. ensuring side-effects of operation are within desired limits), Sustainability (i.e. ensuring uninterrupted operations) and Security (i.e. ensuring authorized access to private health data). Solutions for BAN satisfying the S3 criteria should cover its five principal operations sensing, communication, storage, processing, and actuation; and take into account the interactions among the sensors and the environment. In this regard, from a safety and sustainability perspective, novel formal methods will are presented that model the behavior of the BANs and analyze them for requirement verification. Further, new analysis methodologies are presented to verify the safety and sustainability requirements in a computationally feasible manner, especially for large-scale BANs before they are deployed. From a security stand-point, given the deeply embedded nature of the BANs, a new paradigm for security is covered that is both usable and secure, and makes use of the complexity of the BAN environment (human body) to meet its security requirements.
Energy Scavenging and Battery Power for Long Term Medical Monitoring

Elizabeth K. Reilly
Exponent, Menlo Park, CA

Wednesday, May 25, 2011.
8AM-12 Noon

The tutorial will begin by identifying the different types of ambient energy available for scavenging in the context of Body Sensor Networks. The different types of conversion mechanisms will be discussed and examined in some detail. The physics behind the conversion mechanisms will be explored so that the audience may achieve a greater understanding of how best to design and implement scavenging systems. The tutorial will cover current examples of the different types of scavenging systems and discuss the pros and cons of the state of the art technologies. The tutorial will continue with energy storage systems that are a part of complete energy scavenging system designs. The second part of the tutorial will begin with an overview of current battery design technology for medical devices. Special attention will be paid to the differences in construction for implantable devices versus those used externally. We will also discuss battery lifetime and failure issues.
An Introduction to Inertial Motion Capture

Alexander Young, Martin Ling, and D.K. Arvind
School of Informatics, University of Edinburgh.

Wednesday, May 25, 2011.

Inertial motion capture allows the posture and motion of a subject to be captured without external infrastructure such as cameras. Freedom from infrastructure means that motion capture technology is no longer limited to specialized laboratories. This has applications in a variety of fields, from healthcare, where pervasive motion capture offers new insight into the daily trials of patients going about their normal routine, to animation and human computer interaction. The aim of the tutorial is to introduce attendees to the subject of motion capture using networks of Inertial Measurement Units (IMUs), providing participants with the knowledge necessary to design their own systems. The tutorial is in three parts: an introduction to the basic theory of inertial motion capture, the design of a wireless inertial capture system, and a discussion of applications. Having attended the tutorial participants will have a solid grounding in the theory of inertial motion capture, including its advantages and limitations, enabling them to better understand how this developing technology can be applied to their own specific applications and research interests.
Energy Efficient Custom Integrated Circuit Design for Body Sensor Nodes

Benton Calhoun, University of Virginia
Brian Otis, University of Washington

Wednesday, May 25, 2011.

This tutorial will cover techniques for designing ultra low energy custom integrated circuits to meet the stringent demands of many body sensor-networking applications. Using several fabricated custom ICs an example, the tutorial will encompass digital sub circuits, low voltage SRAM, low power analog sensor interfaces, energy efficient RF circuits, and energy harvesting circuits. For each of these types of circuits, we will describe methods useful for reducing energy consumption and show how they are applied in an example chip. The example ICs includes a wide range DVS processor, an electrocardiogram sensor node, a boost circuit for harvesting thermal power, a low power analog front end for sensors, and a low power MICS/ISM radio. The tutorial will provide instruction in the best approaches for achieving very low energy nodes and show the types of savings that are possible using custom IC hardware for BSNs.
