What are the benefits of Physiological Monitoring?
• Objective
• Quantitative
• Measurable
• Reliable
• Continuous
Introduction
What do we need it for?
• eHealth systems
• Marketing

• Sports, Extreme, Backpacking (Trekking)
• Training
• Security, Military
Introduction
What do we measure?
• Heart Rate (Pulse)
• Sweat (Skin resistance)
• Muscle Activity
• Skin Temperature
• Respiration Rate
• Blood Pressure
• Etc..
Introduction
• Portable• Miniature- compact, light • Nonobstructive, noninvasive • Wireless• Modularity, Multiple uses• Inexpensive • User friendly• Communicate with Smart Phone• Low power• Long battery life
Project’s Requirements
Project’s Goals• Designing the system and appropriate packaging, resulting in a
comfortable, friendly, portable and inexpensive modular sensors system device.
• Creating a unique set of software for Smart Phone and the MSSD, which enables creating a database and storing it for the further inspection.
Project’s Basic Concept
MSSD Smart PhoneInterface
User MSSDInterface
User Smart PhoneInterface
Technical Requirements• Wireless portable system worn on the desirable measurement area.• Ability to simply replace different sensors. • Recognition of maximum 3 sensor channels simultaneously.• Alert for ON-OFF mode, “low-battery” state and BT connection
success. • Physical dimensions of the MSSD is small and nonobstructive.• Storing the data describing each measurement in the Smart Phone
memory by BT for performing extended data processing and better tracking.
• Low-power rechargeable battery.
