Deformations
induced over an antenna by a substrate
subjected to mechanical strain may be
remotely read by processing the
antenna response to a query system.
Thanks to a collaboration with Civil
Engineering researchers we are
developing strain-gouge like RFID tags
useful to be embedded into or over
concrete walls, pillars or a around a
crack to remotely sense the “Health of
a Structure”. Electromagnetic
effort is oriented to govern and shape
the antenna backscattering in presence
of time-dependent boundary conditions.
This technology promises ubiquitous
applications to the emerging concept
of Smart City when a multitude of
low-cost passive radio-sensors will be
scattered all over buildings and
periodically interrogated by moving
stations of by the smartphones of
collaborating citizens.
