PRI researchers developed optical fibre sensing networks for medical applications

7 Mar 2022


Cochlear implantation surgery is the current standard of care to treat profound sensorineural hearing loss. The quality of hearing restored to a deaf patient vastly depends on accurate positioning of the Electrode Array of the cochlear implant while preserving the delicate cochlear membranes.

The research team led by Prof. Tam, Hwa-yaw, Associate Director of the Photonics Research Institute developed optical fibre sensing networks which facilitate medical doctors to monitor and perform surgery.

The team developed fabricated novel ZEONEX based polymer optical fibers integrated with these cochlear implants aid in force detection and navigation in real-time during the implantation process. The low stiffness properties of these fibers compared to the widely used glass fibers can be considered as one of the key features that make them excellent candidates for this surgical prosthesis.

The ZEONEX based polymeric fibers have also been incorporated in the assessment of femoral fracture recoveries. Femoral fracture is a life-threatening injury where early surgical stabilization is now the standard treatment for this injury to allow mobilization and rehabilitation. The outstanding flexibility of these novel fibers together with biocompatibility and insensitivity towards humidity permit them to be utilized with orthopaedic implants to estimate the recovery of the fractured femurs. This is carried out by observing the strain response of polymer optical fiber sensors to various loading and unloading conditions of the femurs.
