Moreover, significant advances in mobile computing, wireless communications, and network technologies, integrated with parallel advances in pervasive and wearable systems, have had a radical impact on modern healthcare systems. Mobile health (m-health) is propelling the evolution of e-health systems from traditional desktop telemedicine platforms to wireless and mobile configurations [20]. 

It is evident that multi fiequency radiometer will have better accuracy for breast cancer detection in comparison with single channel radiometer. But it is not evident that the sensitivity will increase greatly. Thousands of measurements during 10 years with the RTM-Ol-RES radiometer show that there are about 10 percent of breast cancer patients who have no skin temperature increase and brightness temperature increase. So the probability that these patients will have a temperature increase at another frequency is not very high. Due to fte weight and size limitations for a wearable system, there is no reason to use more then two frequencies. Furthermore, skin temperature information is very important for breast cancer detection.

Wearable systems recent advances, materials, and features... 

For wearable systems, including textile antennas, power efficiency represents a crucial matter, especially for the so-called autonomous systems, where the necessary power for the system operation is ideally obtained entirely by means of energy harvesting [16] from the surrounding environment, and no additional power supply is needed. Even in the case of wearable systems equipped with wearable battery units, it is very important to keep power consumption as low as possible. To this aim, several techniques were recently envisaged, by means of innovative textile antennas, such as active antennas as well as the use of multiantenna-processing techniques, such as diversity with multiple wearable antennas.

Due to the physical binding of yams, textile stractures demonstrate good tensile recovery and shear properties, superior conformability, excellent skin contact (especially with knitted stmctures), breathability and comfort. As such, textile structures will provide an excellent platform for creating smart wearable systems. 

In designing wearable devices, there are several factors to consider. The main focus should be that it does not hinder the wearer s movements, unless intended for that purpose. Other important factors include the service life, reusability, the element of design, comfort level and functionality. Garment comfort and appearance is highly affected by the placement of the components. Table 9.2 shows a summary of design guidelines for wearable systems. 

This chapter provides a review of e-textiles, describing the state of the art about research and development of wearable systems reporting the salient characteristics, the manufacturing methods, and the relative functional property characterization and assessment from different levels of integration. Each scientific approach will be followed by some related work carried out by companies, universities, or research institutes. 

Datalogging of the wearable system is done via Bluetooth transmission. As for the instrumented platform, datalogging was done through the RS232 interface.
