Wireless Activity Monitor[WAM]

Background

Blood Pressure Force of Blood against blood vessels Measured with inflatable cuff Measure Systolic and Diastolic pressure

Heart Rate Number of heart beats per minute Measured audibly or electrically Count heart beats per minute

Electrocardiograph (EKG) Monitors heart activity Uses skin electrodes

Problem Statement

Take heart rate readingsTake blood pressure readingsProcess readings onboard the deviceTransmit wirelessly to a local PCPresent data in an intuitive GUIDesign website

Implementation

Wrist MountedCompact2 in 1 unit

Blood pressure Heart rate

Wireless data transmission Determine wireless standard to be used

Use requires minimal instruction

Testing

Data will be acquired from multiple subjectsThis data will be compared to control data

obtained by clinical devicesRange and power consumption testsStudy of human factors associated with final

designCritique of GUI from occupational therapists

(students and faculty)

Budget
