The current common goal in medical information technology today is the design and implementation of telemedicine solutions, which provide chronically ill patients with mobile services that enhance their quality of life, and support and optimize their treatment in case of emergency. Several projects being worked on by FZI and its partners will form a basis for a novel, individual and widespread health monitoring system, which can provide patients with 24h monitoring of their relevant physiological parameters, and therefore optimize their medical treatment and could possibly be life-saving thanks to the enhanced emergency management. In order to be able to build a successful platform for a wide range of medical applications in practice, key factors have been identified which will be introduced in this paper: micro-technological sensors, which are to be used in mobile applications, modularity, a wireless communication network, local intelligence in the form of a powerful mobile information unit, connection to a global network and a conclusive system design for improving the efficiency of health care-related procedures.
