Optimized design and performance analysis of wearable antenna sensors for wireless body area network applications

Over the past decade, the continuous development and the high level of maturity of wireless sensor networks resulted in new networks called wireless body area networks (WBANs), which are an emerging sector of biomedical technology. Moreover, this field has gained significant attention due to its applications which mainly are toward biomedical and healthcare applications. Nowadays, small sensors that can transfer data to other devices can now be implanted anywhere on the human body to record different physiological indicators and enable further actions to be conducted, such as processing, remote procedures and decision aided. Considering this recent hot subject, the intent of this work is to present a new approach of the optimized design and the performance analysis of WBAN specifically channel modelling between wearable wireless sensors. The behaviour of these sensors on the human body is theoretically and experimentally explored in detail along this paper. A good agreement is obtained between the theoretical and the experimental results, although the complexity of the physiological behaviour of human body.
