Wireless heart rate

Keywords— Electrocardiogram, wireless heart rate, heart rate monitor, color coded, ANT+. 

Smart textiles are also available as consumer sportswear, which can monitor parameters such as heart rate and running statistics linking wirelessly to electronic devices such as iPhones, as with the Nike + products or smart phone android apps, as with the Adidas miCoach system. 

Research and development of a heart rate monitor in the sport field began in 1977 when the first wireless electrocardiogram (ECG) heart rate monitor is invented by Polar Electro and used as a training aid for the Finnish National Cross Country Ski team [5,10]. The transmitter was attached to the chest by either disposable electrodes or an elastic chest belt, while the receiver was a watch worn on the wrist.

LabVIEW (computer) The ECG signal is processed by a system developed in LabVIEW to calculate and display the value of heart rate and oxygen saturation. It is also programmed to send the packets of heart rate and oxygen saturation data from the LabVIEW transmitter station via RE module (USB access point), which is wirelessly paired with the existing transceiver in the eZ430-Chronos watch. 

The developed LabVIEW program is able to send the calculated heart rate and oxygen saturation data in real time continuously to the eZ430-Chronos watch via a serial port through the USB RE module. The LabVIEW program(in run mode) will simultaneously interpret the input data and transmit them wirelessly to the watch. 

Eor future development, we are upgrading the wireless watch monitoring system to a wearable miniature processing circuit that is able to transmit three inputs (heart rate, oxygen saturation and temperature) or more to the watch wirelessly and controlled by a PIC16 microcontroller, a smaller processor compared to a computer. The miniaturize circuit can be placed into a sling bag to be worn by the patient and is more portable. 

One of the advantages of the developed wireless health monitoring system is that the person who is responsible to monitor the patient s condition can do it while doing other activities and be alerted instantly when the alarm mode is activated.. It would also be useful in clinics where nurses can be alerted and attend to the patient immediately when the patient s heart rate and percentage of oxygen saturation is out of the normal range.
