Wearable, “…the wrist-worn devices are currently the most publicized areas in wearable technology, with 15.6% of all companies being directly involved…” as according to a research conducted by (IDTechEx, 2014). The most famous wrist-worn device is the smart wristband in the area of fitness and health and sports fitness, where the device is basically a modest computer, which is made in a way that it can be easily fixed on the wrist and monitor the consumers’ fitness through a number of related sensors. In this area, a recent example can be illustrated, where the Microsoft offered such a wrist wearable device, known as the Microsoft Band. The band has an optical heart rate proctor, along with the gyro meter, 3-axis accelerometer, as well as the sensors for skin temperature, ambient light, galvanic skin response, and the capacitive touch (IDTechEx, 2014), as shown in the figure 2 in the Appendix.In addition, the ABI Research also suggests that the most promising area where the wearable technology is used most widely is the health and fitness in today’s market, and by 2017, this area alone can be ranged over 170 million of devices (Kurwa, et al. In this regard, there are some other examples, such as Adidas miCoach for athletes, adiSTAR Fusion used in shoes and sports, Zephyr’s Consumer HxM and BioHarness used for emergency responses, electromyography-sensor-based shirt by university students used to trail the data for exercises, and also the Utope’s fashionable Sporty Supaheroe used for fitness (a jacket with LED showing accelerator, phone calls, and 3D gyroscope) (Ranck, 2012).In the area of medical and E-health, it is suggested that the current market for medical devices in wearable technology is valued at $2 billion in 2011, which is predicted to be tripled by 2016 (TaylorWessing, 2012). For example, the CGM (continuous glucose monitor) is the wearable medical device that is used by diabetes patients, where it provides alerts in advance about the increasing or lowering glucose levels in the patients, which help them to adopt a healthy lifestyle according to their disease (the device architecture is shown in appendix ad figure 3) (Facchinetti, et al. In addition, the healthcare providers are using internet and wearable devices together to trail the patients’ symptoms and connect them to cure, such as medical patches, Tricorder, MEMS sensors, and Pulse Oximetry (Villasenor, 2014).Apart from the medical, fitness, sports and

Figure 3. CGM Sensor architecture. (Source: Facchinetti, et al., 2013). The CGM sensor architecture comprises a commercial CGM sensor (black block) and three software modules for denoising, enhancement, and prediction applied in cascade and working in real time. The denoising module receives in input CGM data and returns in output a smoother CGM profile. The enhancement module receives in input the smoothed CGM data and returns in output more accurate CGM data. Finally, the prediction module receives in input denoised and enhanced CGM data and returns in output the prediction of future glucose value, on which “preventive” hypo- and hyperglycemic alerts can be generated (Facchinetti, et al., 2013).
