Abstract
WristCare is the world's first healthcare device, which monitors the user's well-being 24 hours a day. During the first four days of use, it studies the user's normal activity level and well-being by measuring movement/micro-movement, skin temperature and skin conductivity. If the WristCare system notices a significant change in the user's activity level or well-being, it automatically sends an alarm to the alarm recipient. This way information about the changes reaches its destination in the fastest possible way. The user does not have to worry about the alarms: WristCare automatically sends information about changes even in cases when the user is not able to evaluate his/her own well-being and is not able to send a manual alarm. This is why the WristCare system enables the elderly and chronically ill persons, for example, to live at home for longer than would otherwise be the case. The system also makes home care more efficient, improves the activities of sheltered accommodation(assisted living arrangements)and hospitals.
