The integration of optical fibers into flexible textile structures, by using knitting or weaving processes can allow the
development of flexible light sources. The paper aims to present a new technology: Light Emitting Fabrics (LEF), which
can be used for example for PDT of Actinic Keratosis in Dermatology.
The predetermined macro-bending of optical fibers, led to a homogeneous side emission of light over the entire surface
of the fabric. Tests showed that additional curvatures when applying the LEF on non-planar surfaces had no impact on
light delivery and proved that LEF can adapt to the human morphology.
The ability of the LEF, coupled with a 635nm LASER source, to deliver a homogeneous light to lesions is currently
assessed in a clinical trial for the treatment of AK of the scalp by PDT. The low irradiance and progressive activation of
the photosensitizer ensure a pain reduction, compared to discomfort levels experienced by patients during a conventional
