New Dissolvable Fibre Optic Sensors For In-body Monitoring

Scientists have invented a sensing instrument called fibre optic sensors that are completely dissolvable inside the body and are used for in-body monitoring.

These fibre optic sensors are mainly used to explore sensitive organs such as the brain and to monitor bone fractures. A fibre Bragg grating is an optical element engraved in an optical fibre, which is used as a sensing equipment. According to a study published in the journal optics letters, the new glass fibres are safe for patients even if they break accidently. These sensors reach and access delicate organs within the body and the heart.

Maria Konstantaki from the Institute of Electronic Structure and Laser (IESL) of the Foundation of Research and Technology spoke about the fibre optic sensors, she said, “Our work paves the way towards optical fibre sensors that can be safely inserted into the human body”. She further added, “Because they dissolve, these sensors do not need to be removed after use and would enable new ways to perform efficient treatments and diagnoses in the body”.
