“…Many studies have investigated the challenges and the impact of antennas in body-centric communications [40][41][42]. Measurements in [43] demonstrated (and quantified) the advantage of using a directional patch antenna for the on-body node in an indoor off-body communication scenario, in which a wearable device is connected to a nearby access point.…”

Demographic changes such as the ageing population and the continuous rise of chronic medical conditions such as obesity, diabetes and depression make our healthcare systems economically unsustainable. Sensing technologies are promising solutions that can provide cost-effective answers to these challenges. In this paper, we focus on long-term in-house activity monitoring that aims at early detection and prevention of such conditions. In this context, we present and experimentally evaluate an ultra low-power (less than 100-μW long-term average power consumption) on-body activity sensing prototype system that is based on Bluetooth low energy (BLE). As part of a larger smart home monitoring architecture, the role of the presented system is to collect and reliably deliver acceleration data to the upper layers of the architecture. The system evaluation incorporates a thorough power consumption study that facilitates meaningful battery lifetime estimations, an insightful coverage study in an actual residential environment, and the investigation of energy-efficient packet loss mitigation techniques.

“…It is therefore important to understand and characterise the effects of the human body on the antenna elements. In general, antennas suffer from reduced efficiency, due to electromagnetic absorption in human tissues, radiation pattern distortion, resonance frequency shift (antenna detuning) and variations in impedance at the feed due to antenna-body capacitive coupling [6][7].…”

“…Recently there have been increasing interests in research and development for designing wearable narrowband antennas at 2.45 GHz [6][7][8][9][10][11] but till now there have been no significant breakthrough in the design of wearable antennas. Peter Hall et al has done extensive study on narrowband antenna (2.45 GHz) for on-body communication [8][9].…”

This paper investigates and compares the on-body performance parameters of five different narrowband antennas at 2.45 GHz. Parametrical analysis addressing the human body effects on the performance parameters of different types of narrowband antennas have been presented. The study was performed by combination of numerical simulation and experimental investigation. The antennas used in this study are microstrip fed patch, wire monopole, printed monopole, inverted L and circular loop.

This paper presents a dual band and diverse radiation mode antenna for power efficient and reliable on-body and offbody communications. The antenna is dual band with omnidirectional radiation pattern over the body surface at 2.45 GHz (ISM band) to communicate power efficiently with other colocated body worn devices scattered on the body or body worn base station. At 1.9 GHz (PCS band), it has with directive radiation pattern towards off-the body to communicate power efficiently from on-body device to off-body units/access point or other wider e-health networks. Free space and on-body measured and simulated performances of the proposed antenna are shown and analyzed. The antenna shows very good on-body radiation efficiency as 58.23 % for 1.9 GHz and 50.41 % for 2.45 GHz. In addition, good measured on-body gain is noticed at both frequency bands. Increase of 17.39 % gain at 2.45 GHz is noticed when measured on the body.
