This technology has
applications as a novel sensor device for cerebrospinal
fluid pressure, muscle compartment pressure, arterial blood pressure and other
applications where small pressures magnitudes must be measured with a minimally
invasive sensor.
The key features of the new FBG sensor design
are:
- Small
size: currently 200 µm with potential to be even smaller;
- Greater
pressure resolution than competing FBG sensors of comparable size;
- Non-electrical
(i.e. functional in biological tissue) and biocompatible
- Immune
to electromagnetic interference and therefore potentially compatible with
MRI procedures; and
- High
spatial resolution allowing pressure distributions to be mapped.
FBG sensors fill an emerging
need in the medical devices market. This market is in a phase of intense growth
due to the clinical need to accurately diagnose pathologies with minimally
invasive tools. This opportunity could provide a company with exclusive rights
to the intellectual property and/or a collaborative research arrangement with
the University of Victoria.
