Our Services2 - Personal Wellness Monitoring

Personal Wellness Monitoring

Personal Wellness Monitoring concerns the person’s activity and safety. This area mainly focuses on individuals age 65 or older, but this technology will find applications for the general population. The Personal Wellness Monitoring application presented in this study shows several devices that would be used in managing the care, safety and activity of the residents in an assisted living facility. The information securely collected by these devices is centrally managed and analyzed.

Senior Activity Monitoring Scenario

This use case focuses on monitoring an elderly person’s daily activity. Besides a number of wearable medical sensors/devices that monitor the vital signs (e.g. heart beat, temperature), this use case involves monitoring other non-medical sensors such as environmental sensors, motion sensors, home sensors (e.g. bed, door, window), etc. All the information from these sensors is sent to an IT Platform for recording and processing. The caregiver and/ or family members can, with permission, access this information and assess the well-being of the elderly person. If certain pre-determined events occur, automatic responses could be triggered. For example, the caregiver can be alerted via a text message if the heart rate of the elderly person is above a threshold value.

If an elderly person has to follow a certain daily schedule such as taking a weight measurement in the morning, obtaining glucose level readings at noon and at 6 p.m. and completing an oxygen level reading after dinner, the caregiver can monitor the daily activity status of the person. If certain routine activities are not completed, the person can be sent a reminder. Should the person not respond to set number of reminders, the caregiver can be sent an alarm.

In this use case, the data collection unit and the IT Platform will be able to handle different profiles since they accept and potentially send information from/to both medical and non-medical devices.

The same is true for any devices with multiple sensors, such as a watch with an accelerometer and a gyroscope for fall detection, as well as health-related functions.

This use case also covers journaling. This is a technique that is recommended for patients to help their physicians diagnose certain conditions, such as rheumatic disease. Using this technique, patients record pharmaceutical, environmental or behavioral changes and correlate them with body function changes (e.g. fatigue, motion range, etc.). The information provided by both the patient and by the other medical or non-medical devices in the home network is recorded and stored in a database server for later review by the physician and/or family.

Safety Monitoring Scenario

This case deals with monitoring the safety of the home environment. The home environment is monitored for safety hazards including toxic gases, water and fire. Additionally, the vital signs (e.g. heart beat, temperature) of the persons in the home are also monitored. The data gathered by the medical and non-medical devices is analyzed locally and/ or securely forwarded to an IT Platform for processing and storage. If predetermined events occur, the caregiver and/or family receive alerts. Automatic responses can be triggered when certain events occur.
