A thesis from the UPCT tests the communications of the wireless sensors that we will carry in the body (28/08/2017)

A doctoral thesis from the Universidad Politécnica de Cartagena (UPCT) has tested the most suitable propagation channel for the wireless devices that, more and more, we will carry in the interior or exterior of our body.

The possibility of monitoring the activity of the human body, with medical, sports or entertainment purpose, arouses enormous scientific and social interest for its medical applications, remote diagnosis or constant monitoring;

Its utility for people with disabilities, as an assistant for the blind or to prevent falls;

Their potential in consumer electronics, from wireless headsets to personal identification, through automatic payment or audio / video broadcast to groups;

And their transfer to the location services in the tourist sector or in intelligent transport.

"Multitude of devices can be organized by forming a wireless network to transmit the information they collect," explains the author of the thesis, Rubén Gregorio García Serna.

This body-centered structure is called the WBAN, Wireless Body Area Network.

The thesis, directed by the researchers in Telecommunication of the polytechnics of Cartagena and Valencia, José María Molina and Concepción García Pardo, has experimentally characterized the operation channel of propagation of the emission of the corporal devices both external (off-body) and internal ( In-body).

"The main variation in propagation conditions at the place of placement of the device on the subject.

In the upper body the results are more stable and better communications if the subject is lying down than if he is standing ", summarizes the new doctor, who also has verified that" the effects derived from the breathing are despicable with respect to other sources of Movement in medical devices implanted within the body ".

Researchers have performed the tests using the UWB emission band, from 3.1 to 10.6 GHz, the most appropriate for this type of networks because of their high bandwidth, low emission power, high level of safety, The high temporal resolution and the reduced dimensions of the devices to achieve the objectives of reliability, latency, information security and energy consumption.
