Feasibility of Embroidered Body Worn Antenna as EM Sensor for Radiated Emissions Measurement

In the design of wearable sensors, it is crucial to ensure that the sensors are positioned in close proximity to the object for optimal functionality. Therefore, it is imperative to address environmental requirements to guarantee that the sensors have effective operability. This paper deals with the feasibility of an embroidered body worn antenna usage as electromagnetic (EM) sensor for radiated emissions measurement. The performances feasibility of proposed sensor, made by silver yarns embroidered on a cotton sheet as a radiating element and groundplane, is examined by measuring the radiated emission sourced by some radio frequency (RF) devices. The measurement results demonstrate good receptions of radiated emissions at the frequencies of 2.4 GHz and 2.8 GHz from the source, indicating a promising feasibility of the proposed embroidered body worn antenna as an EM sensor. In addition, the results emphasize the significance of addressing environmental factors in the measurement configuration for optimal performance in sensor applications.
