Wearable body sensor network for health care applications... 

The body sensor network (BSN) systems imbedded in E-Tex can provide health care services such as medical monitoring of physiological signals and ambulatory communication. This WBSN application is growing rapidly. Currently, noninvasive WBSN with multiple types of body sensors are deployed to collect and communicate a wearer s health stams anytime and anywhere as demonstrated by Sotera s Visi Mobile (Fig. 9.2). 

In this chapter, biomedical sensors for wearable computing including their measur-and and measured parameters are discussed, and then the available techniques for the textile-based body sensor networks design are considered. In order to demonstrate the potential benefits of the textile-based wearable wireless body sensor networks, recent development in wireless vital signals monitoring systems based on loT for health care and fitness applications are reviewed. 

Biomedical sensors for wearable body sensor network... 

The sensors employed in wearable body sensor network systems can be divided into active sensors and passive sensors. There is ambiguity in the classification, and many authors are using the other way around. In the biomedical measurement field, however, the definition of sensor type follows the convention of other electronic instrumentation fields the active sensors are those sensors that require an external power source to convert the input into a usable output signal, while passive sensors are those that intrinsically provide their own energy or derive energy from the phenomenon being... 

Pulse oximetry can be integrated into wearable sfructure with woven or embroidered POF textile structures such as a glove or patch for a LED/photodiode sensor together with microcontroller connection. The blood oxygen saturafion (Sa02) data can be interfaced to the WBSN and transferred to the data sink in medical offices for further interpretation and timely intervention. Textile biosensors considered above for WBSN based on E-Tex are summarized in Table 9.2. These textile sensors are flexible and provide good connectivity for integration of E-Tex and body sensor networks. 

Wearable body sensor networks and wireless data acquisition... 

A typical wearable body sensor network consists of multiple types of biomedical sensors and gateway (eg, smartphone or other mobile devices) that can aggregate the data from the sensors and transmit them to remote control servers or cloud. Especially for the textile-based wearable sensors, the sensors might have limited wireless... 

Security design for wearabie body sensor networks... 

However, all the above research studies have focused on secret key distribution issues, while the specific and unique challenge in biometric authentication, ie, how to merge the payload with the biometric information while preserving the statistical uniqueness of the biometric information, has not been addressed. Furthermore, all the above-mentioned biometric-based key-exchange schemes need critical time synchronization because they need to record biometric information simultaneously at different positions of the same human body, which incurs considerable extra communication overhead in extremely resource-constrained wearable body sensor networks. In addition, one of the biometric features may not be unique and accidental faulted measures (eg, due to hardware or software failures) may malfunction the traditional biometric-based security system. 

The future work in wearable body sensor networks will be in several directions (1) provide an accurate and low-cost biometrics-based multiple model selection method to select best biometric features and modes for data authentication (2) develop a key agreement scheme that uses multiple collected dynamic biometric features as a key and share it among communication partners with low communication and computational cost (3) develop a biometric-based authentication system for textile-based body sensor networks under the low-cost key agreement scheme.
