Keynote talk 1



8:30 AM -9:30 AM, Nov. 26th, 2009.




Prof. Nitish Thakor


NeuroEngineering and Biomedical Instrumentation Lab

Johns Hopkins University

Baltimore, MD, USA


Title: Connecting Brain to Hand: Circuits and Signals for Neuroprosthetics


How do our thoughts translate into action? How does brain control our hand? What are the signals that go from the brain to our hand? And, when there is no hand, as in an amputee, how would we tap into brain signals to control an artificial or prosthetic hand? These questions together constitute the outstanding challenge of building a brain machine interface. 


One of the most exciting brain machine interface demonstration of the past few years has been neuroprosthesis. The neuroprosthetic technology comprises an impressive convergence of 1) the neural interface circuits and devices, 2) signal processing and interpretation of neural rhythms, and 3) advanced prosthetic devices with highly actuated limb, hand and digits with multiple degrees of freedom.  This talk will present the state of the art of neuroprosthesis planning the implantable circuit technology, advanced signal processing, neural decoding, prosthesis development - all leading up to a system of brain machine interface.  Implantable circuits and systems span microelectrode arrays and front end neural interface circuits. Signal processing involves methods to decode neural spike activity from a population of neurons or cortical electric rhythms.  These circuits and signals are finally used to drive the prosthetic limb with arm, hand and fingers.  I will discuss the future challenges in building the brain machine interfaces that range from the practical challenges of developing these interfaces for humans to learning about cognitive interfaces for motor, sensory, visual and higher brain functions (and repairing any damage and impairment).

Keynote talk 2



8:30 AM -9:30 AM, Nov. 27th, 2009.





Prof. Chris Toumazou


Director & Chief Scientist

Institute of Biomedical Engineering

Imperial College London

London, UK

Title: Towards Disposable Healthcare Devices; A Paradigm Shift.


We are entering new waves of technology inspired by life style, healthcare, and quality of life. Demands on healthcare throughout the world are changing. The global demographic trend towards ageing populations, coupled with less active lifestyles and fast-food diets, is leading to higher probability and earlier onset of chronic conditions such as Type 2 diabetes and cardiovascular disease. This, in turn, is translating to a substantial increase in the proportion of resources required for long-term, continuous care and a growing burden on healthcare infrastructures.


This talk will review some of the author's work at attempts to provide sensor processing solutions. It will also include his work on a wireless body wave disposable 'digital' plaster, a novel 'low powerless' blood pressure monitor and a point-of-care genetic disposable chip, all created from technologies stemming from the semiconductor industry. Business models and more technologies will be discussed.

Title: MEMS for biomedical and other applications


MEMS (Micro Electro Mechanical Systems) have been fabricated using advanced micromachining based on an extended semiconductor microfabrication.  Micro sensors at the end of catheters for minimal invasive diagnosis and therapy have been developed. These are ISFET(Ion Sensitive Field Effect transistor), pressure sensors, ultrasound imagers, magnetic position sensors, receiving coils for MRI (Magnetic Resonance Imaging), optical scanner and so on.  MEMS have been also developed for other applications. One example is a sophisticated MEMS device used as a high performance rotating gyroscope for navigation control systems. A 1.5 mm diameter silicon ring rotor is electrostatically levitated and rotated at 74,000rpm using high speed digital signal control. The other is a galvanic 2 axis optical scanner for 3D imaging which use a time of flight of light for the distance measurements.  Small size packaged MEMS devices such as integrated capacitive pressure sensor, diaphragm vacuum sensor and MEMS relay for LSI tester have been fabricated by wafer level packaging using a glass with electrical feedthrough.
