Body Temperature Monitoring Internal body temperature, a potential confounding variable in the association between jet fuel constituent metabolism and performance/health measures, was monitored during the enrollee s work period. Selected subjects were asked to swallow a small pill-like sensor. The device provided continuous monitoring of body core temperature during the enrollee s work period. Other enrollees were asked to wear an aural or skin temperature probe. All enrollees wore Polar Band heart rate monitors around the chest area, and activity sensors on the wrist.

The concept of using heart rates as targets for fat burning or cardiovascular workouts is well-established at aU training levels. Commercially, many portable heart rate monitors are available those that measure the electrical frequency of the heart (e.g. Polar,... 

Suunto and Garmin types), and pulse metres, which measure the mechanical pulsation of blood flow in capillaries using photo-reflectance, microphone or pressure bulb. The latter techniques require the sensor to be placed near an artery or on an extremity such as an ear lobe or a finger. As such, it has been said that they may not be reliable under active conditions where the sensor can easily fall off or miss a pulse due to movement (Knight et ah, 2005). However, more recent commercial successes in this area, for example, the Mio strapless heart rate monitor wristband (Mio Global, 2014), seem to indicate that the concerns have been addressed. 

Accelerometers have been worn in many ways. They have been embedded in adhesive patches, belts, shirts, pants as well as in accessories such as straps, wristbands, bracelets, or balls. The integration of accelerometers in flexible wearable medical and sportswear has been explored with some interesting results. In the SensVest project, accelerometers were secured by Velcro straps connected to an adjustable vest and used in conjunction with a heart rate monitor to illustrate the correlation between activity and heart rate levels (Knight et al., 2005). In the SMASH project. Harms et al. (2008a) demonstrated with a small number of subjects that a loose-fitting... 

A number of wristbands or watches are available for monitoring activity and/or heart rate. Two interesting examples are the Mio and EPulse2 strapless heart rate monitors, which measure heart rate using optical pulse detection. Prior to those, the combination of a chest strap with a wrist device was well accepted. 

Heart Rate Monitor—through the use of a thin dielectric film, this dry reusable electrode allows contact that is not affected by heat, cold, light, perspiration, or rough or oily skin. It permits precise heart rate monitoring for cardiac rehabilitation patients as well as professional athletes.

For the cross-scientific approach, a network of four university departments and four industrial companies was formed. The Institute of Electronics and the Institute of Textiles from Tampere University of Technology, the Institnte of Industrial Arts and the Institute of Textile Design from University of Lapland, the snowmobile suit manufacturer Reima-Tutta Oy, compass and navigating systems producer Suunto heart rate monitor producer Polar-Electro Oy, and DuPont Advanced Fibre Systems were the participants. In addition, Siemens and Nokia Mobile Phones assisted with GSM (global system for mobile communication) coimnunications. Altogether, more than ten researchers worked on the project.

EE can be measured by direct calorimetry (heat production of an individual, in calories, when placed in an insulated chamber where the heat is transferred to the surrounding water) or indirect calorimetry (respiratory gas exchange). Additional methods include the eonsumption of doubly labeled water as a marker of heat production and heart rate monitoring, as there is a elose relationship between heart rate and oxygen consmnption during activity. 

Hgure I2b shows a new type of ultrasonic transducer made of piezoelectric composite film. POM/PZT [128]. This transducer is an ultrasonic doppler for feui heart-rate monitoring. A comb-sh d gold electrode is formed on the film by vacuum evaporation. The size of the transducer is 3.5 x 14 cm, and it is loaded by a 6-Vp-p, 13-MHz alternating cunent and receives doppler signals. This transducer can catch fetal heart rate continuously.

Nowadays, the use of a heart rate monitor is very common and not merely use at the hospital as a patient monitor. Generally, heart rate monitor was used by a person who cares about their heart to ensure that they have a normal heart rate. The early detection of the abnormal heart rate can help to prevent from the serious disease. In the sport field, the heart rate monitor is needed to determine the range of heart rate. This range of heart rate should be compatible with the exercise done by an athlete to get an optimum exercise and to prevent from serious injury. 

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. 

In this methodology section, the hardware involved in designing this color coded bracelet heart rate monitoring system is described. Heart rate monitor is an important device to the human health and life [6,7]. Thus, an appropriate communication protocol should be applied.

It can be seen from Table 2 and 3, the color coded is very helpful for training purposes. For example, if a coach wants to Imow whether their athletes are fit or not, it simply can be detected by looking at the Red color of the LED indicator. This invention gives the coach more flexibility and easier monitoring technique instead of manually calculate the heart beat of their athletes. The example of how this portable heart rate monitoring system is worn as a wrist is shown in Figure 2, although the size still needed to be reduce and more reliable for the athletes.

In order to reduce the size, weight and power consumption of the system, a microcontroller based heart rate monitor was implemented. It explains how a single-chip microcontroller can be used to analyze heart beat rate signals in real-time. It can also be used to control patients or athletic person over a long period. Conlan R. W. [8] issued a pattern that describes a small and portable device which detects the frequency and physiological movements, including pulse and may be worn upon the wrist of a user.
