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.
