Tutorial T1

Title: Low Power Wireless ECG Acquisition and Cardiac Stimulation SOCs for Body Sensor Networks
Presenter: Shuenn-Yuh Lee, National Cheng Kung University
Time: 10:10 – 13:10
Location: 16th floor

Abstract: Heart diseases are always the ranked first cause of ten leading causes of death over ten years, and there are several medical devices are made to monitor their heart to avert the heart diseases. In recent years, body sensor networks (BSNs) based applications or devices have become more and more popular, and acceptable to the people for monitoring the real-time health information, such as the electrocardiogram (ECG). In order to enhance the portability and increase the popularization of BSNs, a low-power wireless ECG acquisition system on a chip (SOC) stuck on the body is required. In this tutorial, a bio-signal acquisition system with the features of low power consumption, wireless transmission, and the on-time monitoring will be presented. Moreover, some researches have been reported that it is efficient to electrically generate neural action potential to control dysfunctional organs. Therefore, various implantable microstimulators have been designed for various clinical applications, such as cardiac pacemaker and cochlear implant. The telemetry integrated circuits will be required because they can provide coupling power and are able to transmit or receive data to or from according to implantable body sensor network. In this tutorial, a closed-loop implantable micro-stimulator system on chip (IMSoC), which possesses the sensing of a physiological signal, micro-stimulation, and wireless data/command transmission, will be also presented.



Tutorial T2

Title: How can Compressed Sensing Help Realize Very-Large Scale Embedded Micro Electrode Arrays (VLSE-MEA)
Presenters: Trac D. Tran, Ralph Etienne-Cummings, Yuanming Suo, Jie Zhang, Sang Chin, Johns Hopkins University
Time: 10:10 – 13:10
Location: 15th floor

Abstract: Remote monitoring or wearable and implantable medical devices in a wireless body sensor network setup are becoming more and more popular. However, there are three challenges for these devices, energy efficiency, small factor form and integration with smartphones. The framework of Compressed Sensing and Sparse Representation (CSSR) has demonstrated its advantages for signal acquisition, compression, processing and analysis. In this tutorial, we will examine how to adopt the power of CSSR and utilize it in the wearable and implantable devices. Both the theory and applications (such as Very-Large Scale Embedded Micro Electrode Arrays) will be covered in details. The tutorial will benefit a broad group of researchers from both academia and industry, especially who work on the wearable/implantable/wireless biological signal devices.



Tutorial T3

Title: SMART Neural Prostheses: A tutorial on design, development, and current state of neural prosthetic devices
Presenters: Rahul Samant, Vivian Mushahwar, Ralph Etienne-Cummings and Kevin Mazurek, Alberta Innovates Health Solutions
Time: 14:10 – 17:10
Location: 16th floor

Abstract: Damage to the brain or spinal cord can cause permanent disabilities. These diminish the quality of life of many individuals and cost the US health care system ~$40.5 billion and the Canadian health care system ~$23 billion annually. Because damaged areas in the brain and spinal cord cannot easily regenerate, advanced rehabilitation is the only way to mitigate the effects of these disabilities. The development of neural prostheses enables the restoration of function in individuals with such injuries or diseases. These neural prostheses are electrical systems which interface with the nervous system, examples of which include cardiac pacemakers for restoring normal heart rhythm, cochlear implants for improving auditory performance in individuals with hearing loss, and deep brain stimulators (DBS) for treating some symptoms of Parkinson’s disease.
Sensory Motor Adaptive Rehabilitation Technology (SMART) based Neural Prostheses are sophisticated devices to treat additional disabilities and medical complications, which can be caused by damage in the nervous system. This involves both improving current prosthetic devices to address immediate attention and developing basic technologies for future neural prosthetic applications. The development of these improved neural prostheses will reduce nervous system-related disabilities and improve the health and quality of life of many individuals. Developing technology of this nature requires the organized cooperation of engineers, biomedical researchers, and neuroscientists coupled with doctors, nurses and other workers in rehabilitation medicine.



Tutorial T4

Title: Smart Systems for Healthcare and Wellness
Presenter: Ruud Vullers, IMEC - Holst Centre
Time: 14:10 – 17:10
Location: 15th floor

Abstract: The cost of health care is increasing tremendously in Europe. Innovations are needed to manage illness as well as to manage health. This can be reached by promoting personalized and preventive healthcare. People should be empowered to monitor their own health, be given continuous feedback to improve their health and lifestyle, or just simply be able to enhance their quality of life. This calls for development of technology, that is easy to use, wearable, accurate and comfortable, unobtrusive and affordable.
In this tutorial we will discuss some of the wearable technology being developed. In the case of managing illness, we will focus on EEG and ECG, while in the case of managing health applications we will discuss application for fitness, stress management and environmental sensing.
For all of these applications, the common featured are low power technology, quality of data and ease of use. We will discuss these items in detail. We will also discuss how to power these devices using either batteries or energy harvesting. Finally, we will give live demonstrations of some of the devices that have been developed in our institute.
