Fibre Biomedical Photonics

› Microstructured Polymer Optical Fibre- Holes provide guiding, and sensitivity

› Unique capability at University of Sydney

› Inexpensive to access through ANFF

› PMMA (Perspex)- Extremely low cost – disposable sensors

- Biocompatible / non-hazardous

› “Lab in fibre” - Ultrasensitive molecular detection

- Picolitre volumes

- Long interaction lengths

› But also - On Body (non-invasive), and

- In Body (invasive)

sensing / interfacing opportunities…

Fibre Biomedical Devices› Non-invasive Sensing

- Fibre - sensitive to temperature, bending, pressure…

- Example: Heart rate monitor, integrated with PPE ->

- Potential: Fibre combined with bandage, could provide long term, continuous, inexpensive pressure monitoring, including remotely.

- Also monitor heart-rate, blood pressure, or physical exertion.

› Invasive Interfacing

- Neural interface – channels for:

- Electrical: detection and stimulation

- Chemical: drug delivery

- Optical: optogenetic detection and stimulation

- Developed for neuroscience research
