3. u-Healthcare ? For keeping and being better health For treatment of disease and management of patient u-Health HealthcareWellness U-Healthcare (Ubiquitous Healthcare) Providing health service of “Precaution, diagnosis, treatment, post management” everywhere at anytime USN (Ubiquitous Sensor Network) Environment that collects the information by attaching sensors and manage the real-time information through the network 3

4. Problem of Former Medical Service Hardship of making a appointment because of business Limit of time Hardship of moving to hospital Limit of space Occurrence of cost of time, traffic expenses and hospitalization High cost 4

5. Appearance of u-Health The part that raise the quality of life Conversion of peoples’ recognition Former medical conceptU-Health concept Treatment of disease Management of disease Emphasis on disease Emphasis on medical center     Precaution of disease Care of health Emphasis on quality of life Emphasis on living environment     5

6. Advantage of u-Health Expansion of supplier and consumer Expansion of time and space Care of health at all times without special diagnosis time Recognition of health out of the hospital Several communication or healthcare companies can offer the medical service Healthy people can also use the medical service 6

7. Advantage of u-Health – Contd. Reduction of cost Various services Treatment, examination-> precaution, consultation, custom treatment Reduction of medical cost by precaution of disease and minimization of movement Daily healthcare Change of concept about medical service Improvement of health 7

8. Expected Effects of u-Health Contribution of national welfare through combination of IT, Health and Medical Industry - Change of medical concept on the basis of well-being - New business model or medical model - Expected annual growth is 10~20% in the medical field (Ref:IBM BCS, 2004) User Easy access to a variety of medical information Satisfy the needs for well being Customized and Personalized service Manufacturer New research and development Increase the profit by new product Medical Institution Establishment of quick medical service system Consumer-oriented medical services Improvement of medical service levels Increase the profit Wireless Operator Connected with medical EDI service Cornerstone for the medical market Expected Effects of u-Health 8

9. Previous Research of u-Health Transmission of health information Unconscious measurement of biological signal POLAR, Finland Pulse Samsung, Korea FatPulse ETRI, Korea Pulse, Motion 9

10. Contents 10 u-Healthcare Body Area Network Goals of Research

11.  Current Research of Sensor Network –How can we raise the reliability of data? –How can we avoid the collision of data? –How can we put a device to sleep when there is no packet to transmit? –When we wake up a device? And how? –How can we improve the delivery latency of end-to-end? –How can we transmit when source node is far from sync generator? Research Topics of Sensor Network 11

12. BAN (Body Area Network)  Conventional Concept Establishment of networks by attaching sensors around a person One central node and several local nodes Ref. : IMEC 12

13. USN vs. BAN What is the difference between USN and BAN? USN Many NodesWide Environment Low relation between data packets BAN Several Nodes High relation between data packets Person Routing considering wide environmentRouting considering biological signals 13

20. Research Progress 1st step3rd step2nd step Development of u-Health Monitoring System which transfers biological signal to the portable unit using BAN Research the relation of biological signal and health Development of sensor module The platform design for USN Verification of sensor module Establishment of USN Verification of networking of sensor module and PC Minimize the size of sensor module Development of the portable monitoring unit Health management using Internet 20

21. Requirement for u-Healthcare  Sensor –Reliability –Maintainability –Wearability –Size –Weight –Power Consumption –Security Patch Type 21

22. Digital Bandage for u-Healthcare Digital Bandage –Low Power –Small Size Toumaz company in EnglandDigital Plaster IMEC in BelgiumWireless Sensor Platform 22

23. Expected Effects  U-HEALTH Monitoring System –Healthy life –Reduction of medical expense –Diagnosis and cure anytime, anywhere –Reduce the probability of outbreaks through regular checks –Respond to emergency –Effective health management using internet 23
