Flexible Electromagnetic Interfaces for Wearable Sensors
Résumé
In the last years on-body wireless sensors have been prevailing over wired sensors for the continuous moni-toring of anatomical parameters (e.g., heart and breath rate, blood pressure). However, many of the available solutions are rigid, cumbersome, and do not conform well over the body surface. To this end, it seems cru-cial to go towards a new paradigm of wearable devices designed on flexible substrates that can be easily conformed on one or multiple body parts. Since many of these devices require to communicate with other sensors placed on the body or in its near proximity, the antenna is one of the fundamental elements. Over the years several wearable antennas have been proposed at microwaves [1], with only a few examples in the millimeter-wave (mmW) range [2]. Compared to lower frequencies, mmWs offer the advantages of smaller dimensions, higher data rates, larger bandwidths, and low impact of the bending on the antenna performance. For these reasons, the unlicensed band around 60 GHz is a good candidate for these applications.
