Abstract [en]

Nowadays stress is a frequent problem in the society. Stress level could be important in order torecognise health problems later.Electrocardiogram technics allows to supervise the heart condition and the detection ofanomalies about the patient.Sometimes data collection systems by sensors placed on the patient restrict his mobility.Therefore the elimination of wires is a good solution for this trouble. Then the Bluetooth protocol ischosen as way for transmitting and receiving data between stations. There are three ECG sensorsplaced on the right hand, the left hand and the right leg. It is possible to measure the heart signalwith this technique. Besides there is an extra sensor in order to measure the temperature of thepatient. Depending of the value of these parameters is possible to recognise stress levels. Allsensors are connected to a special box with a microcontroller which treats every signal. Thismodule has a Bluetooth part that transmitts wireless the new digital signal to the receiver. This onewill be a dongle connected to the computer by Serial Port.A program in the computer has been implemented in order to receive the Bluetooth Datasent from the box and saving the data in a file for subsequent activities.
