② Stress Patch App
: Application for receiving and processing data measured in EP300

- IMU measurement frequency, width of data output chart, line thickness, etc. can be set
- Ability to store measured data Excel files (CSV)
- Data received from EP300 is output in real time using graphs and text, and heart rate is calculated based on the data
- PPG (Green, Red, IR) signal output from Galaxy Watch through collaboration with Samsung

2) Meta Health
Provide appropriate stress care content based on the police officer's lifelog (Currently under development)

① Meta Health Watch App
: It is installed on the Galaxy Watch to measure and transmit biometric information desired by the user
 

Data Type	Data Set
Heart Rate	Heart Rate, Heart Rate IBI, Status
PPG Green	PPG Green
PPG Red	PPG Red
PPG IR	PPG IR
ECG	ECG, PPG Green, Lead Off, Sequence, Max / Min Threshold
Accelerometer	X, Y, Z
BIA	Fat Mass, Fat Ratio, Muscle Mass, Muscle Ratio,      Fat Free Mass, Fat Free Ratio, Total Water,      Basal Metabolic Rate, Status
Sweat Loss	Sweat Loss, Status
SpO2	SpO2, Heart Rate, Status

- In the table, a data set is any data that can be measured for a single biometric measurement
ex) When measuring the heart rate, measure the data of the heart rate, heart rate IBI, and status together
- Status is the police officer's current measurement status
ex) Whether the Galaxy Watch is measured by wearing it on the wrist, or if the signal is weak due to movement, etc
- MetaHealth app measures data for 1 minute after countdown when data measurement starts
- Send measured data to the server when the measurement is finished
   · Transfer measured data from the watch to the server immediately if the Internet is available
   · Transfer data measured by the MetaHealth Mobile App to the server
  
② Meta Health Mobile App
: Performs the role of outputting and sending data received from the meta-health watch app to the server and the ability to query the data stored on the server

- Receive data measured from the Galaxy Watch, print it out in graphs and text, and store it
- Send measured data from mobile to server when data measurement ends in Galaxy Watch app
- Data stored on the server can be viewed on a daily, weekly, monthly, or yearly basis

3. TO-BE
- AI algorithms diagnose stress based on data collected with stress patches and Galaxy watches
- Provide mental and physical care content to match diagnosed stress
- Providing a stress report, Prevention of red-flags in health
