Taking good care of aged persons and reducing health care costs become very important issues. Home care is a solution to deal with these issues. The purpose of this study is to develop vital signs measurement platform by using a personal digital assistant (PDA) whose operation system is Windows Mobile 5.0. This system lets user measure vital signs and save data conveniently, and therefore reduces health care costs. The vital signs that were measured in this study are: electrocardiography, pulse, blood pressure and body temperature signals. These analog vital signs were converted into digital signals with a microprocessor; the digitized data were then transmitted to a PDA by a Bluetooth module; finally a user interface on PDA was developed with Microsoft Visual Studio C# 2005. Users can read each vital sign on the screen of PDA at the same time and the system save these signals automatically. A cuff-less blood pressure estimation method was applied to our system to make the system easy to use in home care application.
